Law of Conservation of Linear Momentum | Definition, Formula, Units – Laws of Motion

Linear Momentum Definition:
The total amount of motion present in a body is called its momentum. Linear momentum of a body is equal to the product of its mass and velocity. It is denoted by p.

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

Law of Conservation of Linear Momentum | Definition, Formula, Units – Laws of Motion

Linear Momentum Formula:
Linear momentum, p = mv.
Where,
P = momentum
m = mass
v = velocity

Linear Momentum Unit:
Its SI unit is kg- m/s

Linear Momentum Dimensional Formula:
Dimensional formula is [MLT-1].

  • It is a vector quantity and its direction is in the direction of velocity of the body.

Law of Conservation of Linear Momentum
1. If no external forces acts on a system, then its total linear momentum remains conserved.

2. Linear momentum depends on the frame of reference but law of conservation of linear momentum is independent from frame of reference.

3. Newton’s laws of motion are valid only in inertial frame of reference.

Law of Conservation of Linear Momentum Example:
An example of law of conservation of momentum is Newton’s cradle, a device where, when one ball is lifted and then let go, the ball on the other end of a row of balls will push upward. Newton’s cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres.

Gender Religion and Caste Class 10 Extra Questions and Answer Civics Chapter 4 Short Answers Type

Question 1.
‘Political expression of gender division and political mobilisation on this question helped to improve women’s role in public life?’ Support the statement.
Answer:

  • Yes, these factors have definitely improved women’s status in public domain. They can be seen in almost all fields.
  • We now find women working as scientists, doctors, engineers, lawyers, managers and colleges and university teachers which were earlier not considered suitable for women.
  • In some parts of the world such as Sweden, Norway and Finland, the participation of women in public life is very high.

Question 2.
How can the status of women representation in India’s legislative bodies be improved?
Answer:
It is unfortunate that in our country, the proportion of women in legislature has been very low. For example, the percentage of elected women members in Lok Sabha is just 10 percent. Their share in the state assemblies is below 5 percent. One way to solve this problem is to make it legally binding to have a fair proportion of women in the elected bodies.

Women’s organisations and activists are trying their best in this direction. They have been demanding reservation of at least one-third of seats in the Lok Sabha and State Assemblies for women just as it is in the Panchayati Raj. Let’s see when it converts into a reality.

Question 3.
Give two instances that involve a relationship between religion and politics.
Answer:
(i) Human rights groups in our country have argued that most of the victims of communal riots in our country are people from religious minorities. They have demanded that the government take special steps to protect religious minorities.

(ii) Women’s movement has argued that family laws of all religions discriminate against women. So they have demanded that government should change these laws to make them more equitable.

Question 4.
What factors contribute to the breaking down of age-old caste hierarchy?
Answer:
The old notions of caste hierarchy are now breaking down. The factors that have contributed to it are given below-
(i) Many political leaders and social reformers like Jotiba Phule, Mahatma Gandhi, B.R. Ambedkar, Periyar Ramaswami Naicker, etc. raised voice against this evil and advocated and worked to establish a society in which caste inequalities are absent.

(ii) The contribution of socio-economic changes is worth-mentioning. With economic development, large scale urbanisation, growth of literacy and education, occupational mobility and the weakening position of landlords in the villages, the caste hierarchy is breaking down.

(iii) The Constitution of India has made provisions that prohibit any caste-based discrimination. It has also laid the foundations of policies to reverse the injustices of the caste system. These developments have considerably weakened the caste system in India.

Question 5.
Mention the factors other than caste that matter in electoral politics.
Answer:
Caste matters in electoral politics, no doubt, but other factors equally play important role in election results in India-
(i) The voters have strong attachment to political parties which is often stronger than their attach-ment to their caste or community.

(ii) People within the same caste or community have different interests depending on their economic condition. Rich and poor or men and women from the same caste often vote very differently.

(iii) People’s assessment of the performance of the government and the popularity rating of the lenders matter and often determine the election results.

Gender Religion and Caste Class 10 Extra Questions and Answer Civics Chapter 4 Long Answers Type

Question 1.
‘Gender division is not based on biology but on social expectations and stereotypes’. Explain.
Answer:
It is a fact which can be reflected through the following arguments-
(i) Boys and girls are brought up to believe that the main responsibility of women is house work and bringing up children.

(ii) Women do all work inside the home such as cooking, washing clothes, etc. and men do all the work outside the home. This is reflected in the sexual division of labour in most families.

(iii) It is not that men cannot do house work, they simply think that it is for women to do these things. Similarly, it is not that women do not work outside their home.

(iv) In fact majority of women do some sort of paid work in addition to domestic labour. But their work is not valued.

(v) We see a smaller proportion of girl students go for higher studies. When we look at school results, girls perform as well as boys, if not better in some places. But they drop out because their parents prefer to spend their resources on their boys’ education rather than spending equally on their sons and daughters. The motives of the parents behind this are clear. They think that girls will go to husband’s house after marriage while boys will stay back with them.

Question 2.
Mention various forms of casteism in Indian politics.
OR
What role does caste play in Indian politics?
Answer:
Caste can take various forms in Indian politics-
(i) When parties choose candidates in elections, they keep in mind the caste composition of the electorate and nominate candidates from different castes so as to muster necessary support to win elections.

(ii) When governments are formed, political parties usually take care that representatives of different castes and tribes find a place in it.

(iii) Political parties and candidates in elections make appeals to caste sentiment to win voters’ support. Some political parties favour some castes and are seen as their representatives.

(iv) Universal adult franchise and the principle of one-person-one-vote made political leaders to gear up to the task of mobilising and securing political support.

(v) It also brought new consciousness among the people of castes that were treated as inferior and low until this time.

Question 3.
Explain various forms that communalism can take in politics.
Answer:
Different forms of communal politics are
(i) The most common expression of communal politics is in everyday beliefs. These involve religious prejudices, stereotypes of religious communities and belief in the superiority of one’s religion over other religions. Example Militant religious groups.

(ii) A communal mind aspires for political dominance of one’s own religious community. For those belonging to majority community, this takes the form of majoritarian dominance. For those belonging to the minority community, it can take the form of a desire to form a separate political unit. Example Separatist leaders in Jammu and Kashmir desire to form a separate state.

(iii) Political mobilisation on religious lines is also a form of communal politics. This involves the use of religious symbols and leaders, emotional appeal and fear in order to bring the followers of one religion together in the political domain.

Example— Many of our politicians apply this technique to influence voters from major religious communities.

(iv) Communal politics sometimes takes the form of communal violence, riots and massacre. Example The riots in India at the time of the partition in 1947, the riots of Gujarat in 2002, in Muzaffarnagar in 2013, etc.

Question 4.
What factors have brought about a change in the Indian caste system in modern times? Explain.
OR
Explain the factors that have led to the weakening of the caste system in India.
Answer:
(i) Spread of education has broadened people’s outlook and has changed their mindset especially in urban areas where it does not matter much who is walking along next to us on a street or eating at the next table in a restaurant.

(ii) People in general are becoming more tolerant regarding caste issue. They don’t let caste factor come in between their friendship. They have many things more important than caste to think over.

The old notions of caste hierarchy are now breaking down. The factors that have contributed to it are given below-

(i) Many political leaders and social reformers like Jotiba Phule, Mahatma Gandhi, B.R. Ambedkar, Periyar Ramaswami Naicker, etc. raised voice against this evil and advocated and worked to establish a society in which caste inequalities are absent.

(ii) The contribution of socio-economic changes is worth-mentioning. With economic development, large scale urbanisation, growth of literacy and education, occupational mobility and the weakening position of landlords in the villages, the caste hierarchy is breaking down.

(iii) The Constitution of India has made provisions that prohibit any caste-based discrimination. It has also laid the foundations of policies to reverse the injustices of the caste system. These developments have considerably weakened the caste system in India.

Question 5.
What is communal politics? Describe the idea behind such politics.
Answer:
When beliefs of one religion are presented as superior to those of other religions, when the demands of one religious group are formed in opposition to another and when state power is used to establish domination of one religious group over the rest, this manner of using religion in politics is communal politics.

Communal politics is based on the idea that religion is the principal basis of social community. Communalism involves thinking along the following lines. The followers of a particular religion must belong to one community. Their fundamental interests are the same.

Any difference that they may have is irrelevant or trivial for community life. It also follows that people who follow different religions cannot belong to the same social community. If the followers of different religions have some commonalities these are superficial and immaterial. Their interests are bound to be different and involve a conflict.

In its extreme form communalism leads to the belief that people belonging to different religions cannot live as equal citizens within one nation. Either, one of them has to dominate the rest or they have to form different nations.

Question 6.
Describe how women in India still face discrimination in various ways.
OR
“Women in India continue to be discriminated leading to their unequal position in the society”. Justify the statement.
Answer:
Ours is a patriarchal society in which women face disadvantage, discrimination and oppression in various ways

(i) The literacy rate among women is only 54 percent compared with 76 percent among men. Similarly, a smaller proportion of girl students go for higher studies. The reason is that they drop out because parents prefer to spend their resources for their boys’ education rather than spending equally on their sons and daughters.

(ii) The proportion of women among highly paid and valued jobs is still very small. On an average an Indian woman works one hour more than an average man every day. Yet much of her work is not paid and therefore often not valued.

(iii) In almost all areas of work, women are paid less than men, even when both do exactly the same work.

(iv) Parents’ preference for sons also undermines girls’ existence. In many parts of India parents do not welcome girl child and find ways to have the girl child aborted before she is born. Such sex selective abortion has led to a decline in child sex ratio in the country to merely 914.

(v) Women are not safe even within their own home. They are often beaten and harassed by their husbands and thus become prey to domestic violence.

Question 7.
What are the positive and negative aspects of relationship between caste and politics?
Answer:
Positive aspects
(i) In some situations, expression of caste differences in politics gives many disadvantaged communities the space to demand their share of power. In this sense, caste politics has helped people from Dalits and OBC castes to gain better access to decision making.

(ii) Many political and non-political organisations have been demanding and agitating for an end to discrimination against particular castes, for more dignity and more access to land, resources and opportunities. These efforts have brought many low caste people in the mainstream of the country.

Negative Aspects

  • Politics based on caste identity is not healthy in a democracy because it can disturb social harmony.
  • It can divert attention from other grave issues like poverty, development and corruption.
  • In some cases, caste division leads to tensions, conflict and even violence.

Gender Religion and Caste Class 10 Extra Questions and Answer Civics Chapter 4 Higher Order Thinking Skills (HOTS) Questions

Question 1.
In what ways does politics influence caste system in India?
Answer:
If caste influences politics, politics too influences caste system and caste identities by bringing them into the political domain. Thus, it is not politics that gets caste-ridden, it is the caste that gets politicised. This takes several forms-
(i) Each caste group tries to become bigger by incorporating within it neighbouring castes or sub-castes which were earlier excluded from it.

(ii) Various caste groups are required to enter into a coalition with other castes or communities and thus enter into a dialogue and negotiation.

(iii) New kinds of caste groups have come up in the political area such as ‘backward’ and ‘forward’ caste groups.

Question 2.
Enlist some problems faced by Indian women which affect their social status.
Answer:
Indian women face several problems which affect their career and social status
(i) Women are considered less important than men every where be it home or public space.

(ii) Although they constitute half of the humanity, their role in public life, especially in politics, is minimal in Indian society.

(iii) They are not given equal opportunities in education and career. They are forced to drop out because their parents do not want to spend much on their education.

(iv) On an average an Indian woman works one hour more than an average man everyday. Yet much of her work is not paid and therefore often not valued.

(v) Women are paid less than men, even when both do exactly the same work.

(vi) Women also face the problem of safety even within the wall of the houses. They are often beaten, harassed and exploited by their husbands.

Question 3.
Mention some measures to eliminate inequalities between men and women. v-
OR
Suggest measures to eliminate inequality of women.
Answer:
The following measures can be taken to eliminate inequality of women-
(i) Education need to be spread among women. For this, government should give more attention to their rights from their childhood.

(ii) Vocational training is also important for them. Such training will empower them in various ways and bring them in the mainstream with men.

(iii) The number of women as elected representatives in the Lok Sabha and State Assemblies should be increased. This would be a grand step towards bridging the gap between men and women.

(iv) The government should ensure a safe environment for women so that they may participate in public affairs without any fear or hesitation.

Gender Religion and Caste Class 10 Extra Questions and Answer Civics Chapter 4 Value-based Questions (VBQs)

Question 1.
Which values are associated with feminist movements?
Answer:
Although women constitute half of the humanity, their role in public life, especially in politics, is very small in most societies. Earlier, only men were allowed to participate in public affairs, vote and contest for public offices. Women duties and responsibilities were restricted to home and hearth only.

Gradually, the gender issue was raised in politics. Women in different parts of the world organised and agitated for equal rights. They got support from men also. All these resulted in the emergence of feminist movements. The following values are associated with such movements-

  • Equal rights for women in all spheres of life.
  • Extension of voting rights to all women.
  • Enhancement in the political and legal status of women.
  • Improvement in their educational and career opportunities.
  • Equality in personal and family life. However, in broader sense, feminist movements aim at politi¬cal, social and economic equality of all people regardless of gender.

Question 2.
Why did the Constitution makers of India choose the model of a secular state? Which values are associated with Indian secularism?
Answer:
Our Constitution makers wanted to protect all religions equally. We know India is a country where people from all religions live together. There are Hindus, Muslims, Sikhs, Christians, Parsis, etc. Followers of each religion are free to follow their beliefs and worship as they like. The Indian Constitution does not give a special status to any religion. It prohibits discrimination on grounds of religion.

But Indian secularism means more than that. It does not protect individual’s religious freedom by maintaining a strict separation from religion as happens in other democratic countries. In fact, our Constitution allows the state to intervene in the matters of religion in order to ensure equality within religious communities.

We can give example of the practice of untouchability. The Indian Constitution bans this practice. In this instance, the State intervened in religion in order to end a social practice that it believes discriminates and excludes and that violates the fundamental rights of the people belonging to lower castes. A Secular Constitution like ours is necessary to combat communalism. Although it is not sufficient, it plays an important role in strengthening Indian democracy.

Democracy and Diversity Class 10 Extra Questions and Answer Civics Chapter 3 Short Answers Type

Question 1.
What did the African-American athletes do in order to draw international attention to black poverty in the Mexico Olympic in 1968? (Imp)
OR
How did Tommie Smith and John Carlos try to draw international attention to racial discrimination in the United States at the times of Olympics, held at Mexico city in 1968?
Ans.
(i) In the 1968 Olympics held at Mexico city, Tommie Smith and John Carlos won the gold and bronze medals respectively in the 200 metres race. When the medal ceremony was organised these two Afro-American athletes stood on the dice with clenched fists upraised and heads bowed, while the American national anthem was played.

(ii) They received their medals wearing black socks and no shoes to represent Black poverty. With this gesture, they tried to draw international attention to racial discrimination in the United States.

(iii) The black-gloved and raised clenched fists were meant to symbolise Black power.

Question 2.
Explain how social differences divide similar people from one another but also unite very different people. Give examples. (Imp)
Answer:
(i) People belonging to different social groups share differences and similarities cutting across the boundaries of their groups.

(ii) Both Carlos and Smith were similar in one way— both were African-American and were facing racial discrimination in the United States. Thus, they were different from Norman because he was a white.

(iii) But they were also similar in other ways— they were all athletes who stood unitedly against racial discrimination.

Question 3.
What are the origins of social differences? Describe in brief.
OR
What are the two bases of social differences? Explain them with examples.
Answer:
(i) Social differences are mostly based on accident of birth. Normally we don’t choose to belong to our community. We belong to it simply because we were born into it. We all experience social differences based on accident of birth in our everyday lives. People around us are male or female, they are tall and short, have different physical abilities or disabilities.

(ii) Some of the social differences are based on our choices. For example, some people are atheists. They don’t believe in God or any religion. Some people choose to follow a religion other than the one in which they were born. Most of us choose what to study, which occupation to take up and which game to take part in. All these lead to formation of social groups that are based on our choices.

Question 4.
‘The assertion of social diversities in a country need not be seen as a source of danger’? Support the statement with valid arguments.
Answer:
(i) In a democracy, political expression of social divisions is very normal and can be healthy. This allows various disadvantaged and marginal social groups to express their grievances and ask the government to rectify them.

(ii) Expression of various kinds of social divisions in politics often results in their cancelling one an¬other out and thus reducing their intensity. This leads to strengthening of a democracy.

(iii) People who feel marginalised and discriminated often fight against the injustices. Such a fight often takes the democratic path, voicing their demands in a peaceful and constitutional manner and seeking a fair position through elections. The democratic system in our country tries to accommodate social divisions by reserving seats in various levels of governments for the socially underprivileged people.

Question 5.
Social divisions of one kind or another exist in most countries. Explain. (Imp)
Answer:
(i) Social divisions of one kind or another exist in most countries of the world. It does not matter whether the country is small or big. India is a vast country with many communities. Belgium is a small country with many communities.

(ii) Even those countries such as Germany and Sweden, that were once highly homogeneous, are undergoing rapid change with influx of people from other parts of the world. Migrants bring with them their own culture and tend to form a different social community. Thus, we can say that most countries of the world are multi-cultural in this age of globalisation.

Question 6.
‘All kinds of social differences are not based on accident of birth’. Explain with examples.
OR
‘Some social differences are based on our choices’. Explain with examples.
Answer:
(i) Social differences are mostly based on accident of birth. Normally we don’t choose to belong to our community. We belong to it simply because we were born into it. We all experience social differences based on accident of birth in our everyday lives. People around us are male or female, they are tall and short, have different physical abilities or disabilities.

(ii) Some of the social differences are based on our choices. For example, some people are atheists. They don’t believe in God or any religion. Some people choose to follow a religion other than the one in which they were born. Most of us choose what to study, which occupation to take up and which game to take part in. All these lead to formation of social groups that are based on our choices.

Question 7.
What penalty was imposed on Carlos, Smith and Norman for their action at the 1968 Mexico Olympics? How did the San Jose State University, of which Carlos and Smith were former students, honour them?
Answer:
(i) The International Olympic Association held Carlos and Smith guilty of violating the Olympic spirit by making a political statement. Their medals were therefore taken back.

(ii) When they came back home, they were subjected to a lot of criticism. Norman too suffered for his action. He was not included in the Australian team for the next Olympic.

(iii) The San Jose State University recently honoured them for their brave action and installed their statue in the University campus.

Question 8.
Enlist three features of Civil Rights Movement that took place in the USA during 1954-1968?
OR
Explain the Civil Rights Movement in the United States.
Answer:
(i) The Civil Rights Movement in the US refers to a set of events and reform movements aimed at abolishing legal racial discrimination against African-Americans, also called blacks.

(ii) This movement was led by Martin Luther King Jr., an American Baptist Minister, activist and humanitarian. He led this movement using non-violent methods of civil disobedience against racially discriminatory laws and practices.

(iii) The movement broke the pattern of public facilities being segregated by race in the Southern US and achieved the most important breakthrough in equal-rights legislation for African-Americans.

Question 9.
What happened in the Olympic Games of 1968?
Answer:
(i) In the 1968 Olympics held at Mexico city, Tommie Smith and John Carlos won the gold and bronze medals respectively in the 200 metres race. When the medal ceremony was organised these two Afro-American athletes stood on the dice with clenched fists upraised and heads bowed, while the American national anthem was played.

(ii) They received their medals wearing black socks and no shoes to represent Black poverty. With this gesture, they tried to draw international attention to racial discrimination in the United States.

(iii) The black-gloved and raised clenched fists were meant to symbolise Black power.

Question 10.
‘Every expression of social divisions in politics does not lead to disasters’. Support the statement with three valid arguments.
Answer:
(i) Social divisions of one kind or another exist in most countries. Wherever they exist, these divisions are reflected in politics. In a democracy political parties talk about these divisions, make different promises to different communities, look after due representation of various communities and make policies to redress the grievances of the disadvantaged communities.

(ii) Social divisions affect voting in most countries. People from one community tend to prefer some party more than others.

(iii) In many countries there are parties that focus only on one community.
The instances given above clearly show that expression of social divisions in politics does not lead to disasters nor does it lead to disintegration of the country.

Question 11.
What is the main difference between the Civil Rights Movement and the Black Power Movement?
Answer:
The Civil Rights Movement practised non-violent methods of civil disobedience against racially discriminatory laws and practices in the US. On the other hand, the Black Power Movement was a more militant anti-racist movement, advocating even violence if necessary to end racism in the US.

Democracy and Diversity Class 10 Extra Questions and Answer Civics Chapter 3 Long Answers Type

Question 1.
Explain overlapping and cross-cutting social differences. (Imp)
Answer:
Overlapping social differences

Social division takes place when some social differences overlap with other differences. The difference between the blacks and whites becomes a social division in the US because the Black are poor and Whites are rich. In our country Dalits tend to be poor and landless while some other communities are well-off. Situation of this kind creates social divisions, when one kind of social difference becomes more important than the other and people start feeling that they belong to different communities. This situation can lead to disintegration of the country.
In Northern Ireland, class and religion overlap with each other. Catholics are poor while Protestants are wealthy there. This results in conflicts and tensions.

Cross-cutting social differences

By cross-cutting social differences we mean that groups that share a common interest on one issue are likely to be in different sides on a different issue. In the Netherlands, class and religion tend to cut across each other. Here both Catholics and Protestants are about equally likely to be poor or rich. This results in a mutual coordination between the two groups which ultimately strengthens the basic foundation of the country.

Question 2.
How does social division take place? Explain with example.

Question 3.
Why do some people think that politics and social divisions must not be allowed to mix? Explain giving reference to Northern Ireland and Yugoslavia.
OR
Explain with reference to Northern Ireland the ways in which social divisions have resulted in violent and bitter ethnopolitical conflict.
OR
The combination of politics and social divisions is very dangerous and explosive. Explain highlighting the case of Northern Ireland.
Answer:
(i) Northern Ireland of the United Kingdom has been for many years the site of a violent and bitter ethnopolitical conflict. Its population is divided into two major seats of Christianity – 53 percent are Protestants, while 44 percent are Roman Catholics.

(ii) The Catholics were represented by Nationalist parties who demanded that Northern Ireland be unified with the Republic of Ireland, a predominantly Catholic country. The Protestants were represented by Unionists who wanted to remain with the UK, a predominantly Protestant country.

(iii) The conflict between the two sects became bitter when Unionists and Nationalists started fighting. Hundreds of civilians, militants and security forces were killed in this fight. There was also fight between the security forces of the UK and the Nationalists.

(iv) In 1998, the UK government and the Nationalists reached a peace treaty after which the latter suspended their struggle.

(v) In Yugoslavia, political competition along religious and ethnic lines led to the disintegration of the country into six independent countries. These are the reasons why some people think that politics and social divisions must not be allowed to mix.

Question 4.
Explain the reasons of social differences.
OR
What are the factors that create social differences in society?
Answer:
There are several reasons of social differences:
(i) Differences based on accident of birth:
Social differences are mostly based on accident of birth. Normally we don’t choose to belong to our community. We belong to it simply because we were born into it. We all experience social differences based on accident of birth in our everyday lives. People around us are male or female, they are tall and short, have different physical abilities or disabilities.

(ii) Differences based on choice:
Some of the social differences are based on our choices. For example, some people are atheists. They don’t believe in God or any religion. Some people choose to follow a religion other than the one in which they were born. Most of us choose what to study, which occupation to take up and which game to take part in. All these lead to formation of social groups that are based on our choices.

(iii) Differences based on religion: It is fairly common for people belonging to the same religion to feel that they do not belong to the same community, because their caste or sect is very different. It is also possible for people from different religions to have the same caste and feel close to each other.

(iv) Differences based on economic states: We see a wide gap between the rich and the poor. The affluent class of the society leads a very luxurious life while the poor are destined to lead a tough life in spite of doing hard work. Such a situation creates social divisions. We often see that rich and poor persons from the same family often do not keep close relations with each other for they feel they are very different.

(v) Differences based on caste and colour: History shows that people are often differentiated due to their caste and colour. In the US, the Blacks tend to be poor, homeless and discriminated against. On the other hand, the Whites are well-off and lead a life of comforts. In India, Dalits tend to be poor and landless while the upper caste people are mostly rich and affluent.

Question 5.
Three factors are crucial in deciding the outcome of politics of social divisions. Explain. (Imp)

Democracy and Diversity Class 10 Extra Questions and Answer Civics Chapter 3 Value-based Questions (VBQs)

Question 1.
Tommie Smith and John Carlos, the two Afro-American athletes stood against racial discrimination. Peter Norman, who was neither Black nor American, supported their cause by joining in the gesture of protest. What values do the three people promote by their action?
Answer:
Their action promotes human values. Smith and Carlos were blacks and had suffered a history of discrimination. They were differentiated on the basis of their colour. They were forced to live a life of miseries. When they got a suitable opportunity, they resisted the practice of racial discrimination in the US.

They wanted equal treatment, respect and equal opportunities for all human beings irrespective of their caste, creed, colour or race. They wanted to live a life of decency and self-respect. These are high human values which are essential for all. So far Norman Peter is concerned, he supported their cause to show that he was against racism and preferred a society where equality existed.

What is Impulse in Physics? | Definition, Examples, Formula, Units – Laws of Motion

Impulse Definition Physics:
The product of impulsive force and time for which it acts is called impulse.

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

What is Impulse in Physics? | Definition, Examples, Formula, Units – Laws of Motion

Impulse Formula Physics:
Impulse = Force x Time = Change in momentum.

Unit for Impulse:
Impulse SI unit is newton-second (N-S) or kg-m/s

Impulse Examples in Physics:
1. Airbags are used in automobiles because they are able to minimize the effect of the force on an object involved.
2. You’re playing pool, and you strike a pool ball with the cue. The cue may be in contact with the ball for only a millisecond, but there’s an observable result — the ball is now in motion. That is a result of impulse.

Impulse Dimensional Formula
dimensional formula is [MLT-1].

  • Impulse is also equal to change in momentum of the object.
  • It is a vector quantity and its direction is in the direction of force.

Note:
Total impulse for the force applied during period t1, to t2 = Area under the F-t curve from t1 to t1.

Laws of Motion:
There are various laws in Physics that define the motion of the object. When an object is in motion whether it is linear or circular there is some force which is always imposed on it.

What is Inertia of Motion Force
Law of Conservation of Linear Momentum Impulse
Laws of Motion Rocket
Equilibrium of a Particle Weight
Friction Motion on a Rough Inclined Plane

What is Force in Physics? | Definition, Formula, Types, Units – Laws of Motion

Force Definition Physics:
Force is a push or pull which changes or tries to change the state of rest, the state of uniform motion, size or shape of a body.

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

What is Force in Physics? | Definition, Formula, Types, Units – Laws of Motion

Force SI Unit:
Its SI unit is newton (N)

Force Formula Physics
F = m.a
Where,
F = Force
m = mass of an object
a = acceleration

Dimensional Formula of Force:
Dimensional formula is [MLT-2].

Types of Forces in Physics:
Forces can be categorised into two types:

  1. Contact Forces
  2. Distant Forces

(i) Contact Force Definition:
A contact force is any force that requires contact to occur. The contact force acts on a point of direct contact between the two objects.

Contact Force Examples:
Frictional force, tensional force, spring force, normal force etc are the contact forces.

(ii) Distant Force Definition:
The Forces are those types of forces that result even when the two interacting objects are not in physical contact with each other.

Distant Force Examples:
(Field Forces) Electrostatic force, gravitational force, magnetic force etc are action at a distance forces.

Impulsive Force in Physics
A force which acts on a body for a short interval of time and produces a large change in momentum is called an impulsive force.

Impulsive Force Examples:
1. when you hit a ball with a cricket bat, you apply a force for a time(a very short period in this case) to cause a change (or transfer) of momentum in the ball.

2. A hammer, the collision of two billiard balls.

Laws of Motion:
There are various laws in Physics that define the motion of the object. When an object is in motion whether it is linear or circular there is some force which is always imposed on it.

What is Inertia of Motion Force
Law of Conservation of Linear Momentum Impulse
Laws of Motion Rocket
Equilibrium of a Particle Weight
Friction Motion on a Rough Inclined Plane
Motion of Bodies in Contact Pulley Mass System
