Power Formula: Derivation of Power formula, Examples

We all are very familiar with power. Also, it helps us to measure the energy that we use to do the work. In this topic, we will discuss what is power and what is Power formula, its derivation and solved examples.


Power refers to the quantity of work done by a body. Also, quantity work has to do with a force causing a displacement. Moreover, work has nothing to do with the amount of time, which this force acts to cause the displacement. In addition, there are times when we do work quickly and there are times when we do work rather slowly.

Power Formula

For example, a trail hiker (One who selects an easier path up the mountain) can elevate her/his body a few meters in a short amount of time. On the other hand, a rock climber might take relatively more time to elevate her/his body up a few meters next to the side of a cliff.

Although, both of them do the same work but the rock climber might take more time than the trail hiker. Also, the quantity that has something to do with the rate at which a certain amount of work is done is called power. Besides, in the above case, the hiker has greater power rating than the rock climber.

Power Formula

We can refer to power as the rate at which we do work. Also, it is the ratio of work and time. Besides, we calculate it mathematically using this formula or equation.

power as the rate at which we do work

Derivation of Power formula

Power = unit of measure (Watt)
W = work done by the body
t = time taken to do the work

Moreover, the standard unit of measuring power is Watt. According to the power formula, a unit of power is equal to a unit of work divided by a unit of time. Also, a watt is equal to Joule/ second.

Besides, due to historical reasons, power is occasionally used to describe the power delivered by a machine. In addition, one horsepower equals 750 Watt.

Suppose that there is a car engine of 40 horsepower that could accelerate from 0 mi/hr to 60 mi/hr in 16 seconds. Moreover, if there is a car that has four times the horsepower that could do the same work in one-fourth the time. That means a 160 horsepower engine could accelerate the car from 0 mi/hr to 60 mi/hr in just 4 seconds.

Here the point is that for some amount of work, power and time are inversely proportional. Moreover, it means that a more powerful engine can do the same work in less time.

Solved Examples on Power Formula

Example 1

Suppose that Mr. X elevates his body of 80 kg up by a 2.0-meter stairwell in 1.8 seconds. Also, in this case, then we could calculate Mr. X power rating. Besides, we must assume that Mr. X must apply an 800 Newton downward force upon the stairs to elevate his body. In addition, by doing this the stairs would push upward on Mr. X body with just enough force to lift his body up the stairs.

Besides, we can assume that the angle between the force of the stairs on Mr. X and Mr. X’s displacement is 0 degrees. Then power can be resolute as shown below:

Solution: Power = Work/Time

W = 871 Watts.

So, Mr.X power rating is 871 Watts.

Example 2

Calculate the power that a person requires to lift an object to a height of 8 m in 10 seconds. Also, the mass of the object is 10 kg. Besides, take g = 10 m/s^2

Solution: For calculating work first find the work done by the person which is equal to the potential energy at that height

Work (W) = mgh = 10 × 8 × 10 = 400J

Power =  Work/Time = 800/10 = 80 J/s.

Formula for Velocity: Concepts, Formulas and Examples

Everybody knows about velocity but there is a misconception about it. The misconception is that speed and velocity are the same things but in reality, it is just the opposite. Besides, most of the people consider them the same and use them interchangeably. Moreover, they are quite similar but they are not same. Besides, in this topic, we will talk about formula for velocity.


It refers to the rate of change in displacement with respect to time. Furthermore, distance and displacement are the key points of the velocity. Also, if there is no displacement in objects potion and the object do not cover any distance then there will be no velocity.

Hence, what is the difference between displacement and distance? Displacement refers to the net change in the position of an object in motion. On the other hand, distance refers to the amount of ground covered by an object in motion.

Velocity Formula

Moreover, distance is a scalar quantity because it can be described with the help of only the magnitude and it has no reference with direction. Whereas, displacement is a vector quantity because it is fully described with both direction and magnitude. In addition, velocity is the function of displacement and is also a vector quantity.

Velocity Formula

Now let’s look at the formula of velocity. As discussed earlier, velocity is a change in objects displacement over time. In simple words, velocity is a measure of how much time an object takes to reach a destination with direction. Moreover, it is directly related to displacement and inversely relates to the time traveled. Also, its unit is meter per second (m/s).

Velocity formula = displacement ÷ time

Displacement = final position – initial position or change in position

Time = taken to cover the distance.

Now let’s take some values to understand the formula clearly. Suppose Mr. X initial position is ai and his final position is af and he has taken t time to cover this distance then the equation will be.

v = af – ai / t = a / t


v = velocity which is m/s (meter per second)

af = final position of X

ai = initial position of X

t = time taken by the object to move along the distance (s)

a =change in position (final – initial) (m)

Solved Example on Velocity Formula

Now let’s test the equation with the help of examples.

Example 1- Suppose there is an object traveled a distance of 10 meters in the left direction and the time taken by the object is 2 minutes. Find the velocity of the object.


Now recall the formula which is velocity = displacement ÷ time

v = a / t

Now put the values in the formula. But first of all change minutes into time by multiplying minutes by 60.

Time in seconds = time in minutes × number of seconds in a minute

ts = 2 × 60 = 120 s

So, time in seconds is 120 s

v = 10 / 120

v = 0.08 m/s

The velocity of the object is 0.08 m/s.

Example 2- Now let’s discuss another problem where we know the value of velocity and time and we have to calculate displacement. The value of velocity and time is 1.5 m/s and time taken is 100 seconds. Find the value of displacement.


Now recall the formula which is velocity = displacement ÷ time

v = a / t

Now put the value in the formula

v = a or a / t

1.5 = a ÷ 100

1.5 × 100 = a or

a = 1.5 × 100 = 150 m

The displacement is 150 m.

Density Formula: Meaning, Definition, Solved Examples

Density is a basic and fundamental concept in physics and engineering. Furthermore, it has a strong relationship with the mass of an object. Moreover, this measurement is essential in determining whether something would float or not on a fluid’s surface. Density is certainly one of the most important details you can know about an object. Learn the density formula here.

What is Density?

Density refers to the measurement of the amount of mass of a substance per unit of volume. This measurement of a pure substance has the same value as its mass concentration. Densities vary with different materials or substances. Moreover, this particular measurement of a material can be relevant to purity, buoyancy, and packaging.

One can simplify this measurement’s comparisons across the different systems of units. The replacement of this measurement with a concept is known as relative density can sometimes take place. Relative densities refer to the ratio of a substance’s density to a standard substance or material, usually water.

Density Formula

The densities of materials show variation with pressure and temperature. This variety is comparatively small for solids and liquids but significantly greater when it comes to gases. When the pressure on an object increases, then consequently the volume decreases. This ultimately causes an increase in this particular measurement of the object.

Also, increasing a substance’s temperature results in a decrease in this measurement. This is due to the increase in volume. Heating the bottom of a liquid in most cases results in a decrease in this measurement of such heated liquid.

Density Formula

Densities refer to the measure of relative compactness. The definition of this measure can be expressed as mass, m, in a particular volume, v. Most noteworthy, the symbol ρ is mostly made use of for expressing this measurement. Furthermore, this symbol happens to be the lower case Greek letter rho. Some individuals also make use of the letter D for expressing this measurement.

Solved Example on Density Formula

Q1. Find out the density of a cube of sugar which weighs 12 grams and measures 2 cm on a side?

Answer: This question can be completed in two steps

Step 1: Derive the mass and volume of this sugar cube

Mass = 12 grams

Volume = 2 cm sides

The volume of a cube = (length of side)3

Volume of cube = (length of side)3

Volume = (2)3

Volume = 8 cm3

Step 2: Putting the variables into the formula

Density = mass/volume = 12 grams/8 cm3

So, it comes out to be = 1.5 grams/cm3

Hence, this sugar cube has a density of 1.5 grams/cm3.

Q2. A particular solution of salt water contains 20 grams of salt and 200 grams of water. Find out the density of the salt water? (note = density of water is 1 g/mL)

Answer: Step 1: Derive the mass and volume of the salt water.

Mass of salt = 20 grams

Density of water = mass of water/volume of water

Mass of water = 1 g/mL multiplied by 200 mL

Therefore, the mass of water = 200 grams

Now, one can find out the mass of the saltwater

Mass of salt water = mass salt + mass of water

Mass of salt water = 20 g + 200 g

So, mass of salt water = 220 g

Also, the volume of salt water is 200 mL.

Step 2: Putting these values into the formula

Density = mass/volume = 220 g/200 mL

So, it comes out to be = 1.1 g/mL

Hence, this salt water certainly has a density of 1.1 g/mL.

Acceleration Formula: Definition, Speed, Solved Examples

You must have heard of the term acceleration in your daily life. If we look at it in general, acceleration is said to be when an object is increasing its speed cautiously. In other words, it means if you are traveling in a car which is moving at the speed of 60 kmph and after 1 min the speed of the car is 65 kmph, which means you are accelerating. Now the question arises that how can you say that this object is accelerating? What are the terms taken into consideration during the calculation of acceleration? We will dive deeper below and learn the acceleration formula.

Acceleration Formula | Definition

In general, we can say acceleration refers to speeding up. However, from the physics perspective, we see it means something different. Over here, it is referred to as the rate at which the velocity of an object changes. It does not matter if it is speeding up or down, it’s the change.

Therefore, the acceleration is positive when the object is speeding up and negative when speeding down. According to Newton’s Second Law, the net unbalanced force which acts on the object causes this to happen. Thus, it can be said that acceleration is a vector quantity. It is so because it changes the time rate of change of velocity.

Learn more about Newton’s Laws of Motion here.

Formula for Acceleration

There are two formulas for acceleration. The first formula is from Newton’s second law relates force, mass, and acceleration in an equation. Thus, the formula is:

F= ma

Over here:

F refers to the force

m is the mass

a is the acceleration

Further, we have another formula that is made to calculate the rate of change in velocity over the period of time. Therefore, the formula for this is:

Formula for Acceleration

Solved Examples on Acccerelation Formula

Question- A woman is traveling by her sports car at a constant velocity v = 5.00 m/s. When she steps on the gas, it makes the car to accelerate forward. Further, past 10.0 seconds, she stops the acceleration and continues a constant velocity v = 25.0 m/s. Calculate the acceleration of the car.

Answer- In the forward direction, initial velocity is

Solved Examples on Acccerelation Formula

Therefore, we see that the acceleration of the car is 2.00 m/sforward.

Question- A man takes a rock and drops it off from a cliff. It falls for 15.0 s before it hits the ground. The acceleration due to gravity g = 9.80 m/s2. Calculate the velocity of the rock the moment before it had hit the ground.

Answer- The man released the rock from rest, therefore, we get the initial velocity as


 = 0.00 m/s. The time for the change to take place is 15.0 s. The acceleration for this is 9.80 m/s2. Therefore, to find the velocity we will rearrange the equation like:

Calculate the velocity of the rock the moment before it had hit the ground

Therefore, as the rock is falling, the direction of the velocity is down.

Pendulum Formula: Definition, Pendulum Equation, Examples

A pendulum is one of the most common items found in most households. It is a device that is commonly found in wall clocks. This article will throw light on this particular device and its functioning. After that, students will be able to easily understand how it operates and the reason behind its harmonic motion. Learn pendulum formula here.

Pendulum Definition

A pendulum is essentially a weight that is hung from a fixed point. It is placed in such a way that it allows the device to swing freely to and fro. The pendulum bob of a simple pendulum is treated as a point mass. Further, the string from which it’s hanging is of negligible mass.

If you look at it from the perspective of physics, you will find these simple pendulums quite intriguing. This is so because they serve as a great example of simple harmonic motion, which is much similar to rubber bands or springs.

Pendulum Equation

Pendulum Equation
Pendulum Equation

There are a lot of equations that we can use for describing a pendulum. Firstly, we have the period equation which helps us calculate how long the pendulum takes to swing back and forth. We measure it in seconds. Thus the period equation is:

T = 2π√(L/g)

Over here:

T= Period in seconds

π= The Greek letter Pi which is almost 3.14

√= The square root of which we include in the parentheses

L= The length of the rod or wire in meters or feet

G= The acceleration due to gravity (9.8 m/s² on Earth)

Next up, we have the frequency equation. This calculates the numbers of times a pendulum swings back and forth within a second. We measure that in hertz. Thus, the frequency equation is:

f = 1/T

f = 1/[2π√(L/g)]

Over here:

Frequency f is the reciprocal of the period T:

Further, we have the length of the wire. You can easily find the length of the wire or rod for a specified frequency or period. Have a look at the equation given below to know more:

f = [√(g/L)]/2π

2πf = √(g/L)

So, when you have this, you will need to square both sides of these equations. That results in:

4π2f2 = g/L

When you solve for L, you will get:

L = g/(4π2f2)

Similarly, the length of the wire for a given period is:

T = 2π√(L/g)

Then, you after squaring both the sides we get:

T2 = 4π2(L/g)

Thus, when you will solve for L, you will get:

L = gT2/4π2

Solved Example on Pendulum Formula

Question– A pendulum’s length is 4 meters. It completes one full cycle of 0.25 times every second. The maximum displacement that the pendulum bob reaches is 0.1 meters from the center. Find out the time period of the oscillation? And what is the displacement after 0.6 seconds?

Answer– To begin with, make sure to write down the information which you already know. So, by far, we already know the length of the pendulum (L= 4 meters). Then, the pendulum’s frequency is 0.25 (f- 0.25). Similarly, the amplitude or maximum displacement is 0.1 and time is 0.6 (A= 0.1 and t=0.6). Finally, the acceleration due to gravity, as always is 9.8 (g=9.8). So, you need to find T.

In order to find T, you need to simply plug numbers into this equation and solve it accordingly. So, you have the equation of 2π times the square root of 4 which you will divide by 9.8. Thus, the equation will be:

2π × 0.64

2 × 3.14 × 0.64 = 4.01

Therefore, the time period of the oscillation is 4.01 seconds.

Father To Son Central Idea of the Poem

The central idea of the poem is the generation gap which occurs when the communication link between two generations breaks due to a mutual lack of understanding, tolerance and acceptance. The poem reveals an internal conflict that a father undergoes when his son grows up and possesses his own interests, ideas and perceptions. The unhappy father complains that he cannot understand his child despite having lived together, for so many years in the same house. Instead of bonding together, they have drifted apart. The gap has resulted in non-communication and non- understanding of each other. If both of them decide to take a lead and are willing to forget and forgive, their relationship may improve. Respecting each other’s differences is the only way out to diminish the distance between parents and children.

Father To Son Poem Summary in English

Father To Son Stanza Wise Explanation of The Poem

Stanza 1
I do not understand this child
Though we have lived together now
In the same house for years. I know
Nothing of him, so try to build
Up a relationship from how
He was when small.

Word Meanings
understand – know
for years – for many years
build up – develop
Explanation The father unhappily reflects on his inability to understand his own son. They have been staying in the same house for years but, due to non- communication and a lack of understanding, both son and father are not able to understand each other. The father does not know much about his son’s interests, likes or dislikes. Thus, he try to build up the same kind of relationship as he used to have when his son was a little child. The father has now perhaps realised that there is a lack of understanding between his son and himself and he wants to take measures so that their relationship improves.

Stanza 2
Yet have I killed
The seed I spent or sown it where
The land is his and none of mine?
We speak like strangers, there’s no sign
Of understanding in the air.
This child is built to my design
Yet what he loves I cannot share.

Word Meanings
strangers – unknown to each other
sign – indication
in the air – known
cannot share – do not

Explanation The father wonders whether it is he himself who is responsible for the failure of the relationship. The father feels that though the child is his son but perhaps he lives in a world different from him. Both father and son behave like strangers. There is lack of understanding and a communication gap which makes them behave not like father and son but more like strangers. The father says that physically the child resembles him but he does not appreciate what his son likes.

Stanza 3
Silence surrounds us. I would have
Him prodigal, returning to
His father’s house, the home he knew,
Rather than see him make and move
His world. I would forgive him too,
Shaping from sorrow a new love.

Word Meanings
silence – here it means lack of communication
surrounds – everywhere, all over
prodigal – extravagant, wasteful
move his world – shift to newer avenues
shaping from sorrow – making something new

Explanation: Silence surrounds their relationship because there is a complete lack of communication between them. The father sees his son as a prodigal (meaning, a child who foolishly mns away from home) and wants him to return to the home he has always known, so that they can rebuild the relationship to have a new start. He does not want the son to start life afresh without the father. He further says that he is willing to forgive his son for running away. Here the father’s tone is somewhat condescending, implying that the father is unable to let his son go, despite restricting the son’s independence and development.

Stanza 4
Father and son, we both must live
On the same globe and the same land,
He speaks: I cannot understand
Myself, why anger grows from grief.
We each put out an empty hand,
Longing for something to forgive.

Word Meanings:
same globe – this world
grows from grief – develops from deep sorrow
put out – extend
longing – desiring keenly or strongly

Explanation: Both fathers and their sons all over the world must learn to live together in spite of their misunderstandings and differences. At this point in the poem, the son speaks for the first time and admits that he too feels the sadness of the broken relationship, but he is angry due to his confusion. Both father and son want to forgive each other, but neither is ready to take the first step of asking for forgiveness from the other. However, the situation can improve if they find a way of getting closer to each other.

Father To Son Poetic Devices Used in the Poem

Antithesis: In this figure of speech two contrasting or opposing ideas are put together. For example
(a) The land is his and none of mine
(b) Shaping from sorrow a new love

Alliteration: This indicates occurrence or repetition of the same sound or letter at the beginning or most of the words in a sentence. For example
(a) Silence surrounds us
(b) The seed I spent or sown
(c) The home he knew
(d) Shaping from sorrow

Metaphor: In this figure of speech, an implied comparison is made between two unlike things that actually have something in common. For example
(a) The land is his and none of mine
(b) We both must live on the same globe and the same land

Synecdoche: In this figure of speech a part is made to represent the whole or vice-versa. For example
(a) – Make and move his world

The Voice of The Rain Central Idea of the Poem

The poem The Voice of the Rain’ by Walt Whitman signifies the eternal role that the rain plays in nurturing, quenching and purifying the various elements of Earth. The rain returns the favour to its place of origin from where it rises unseen from the depths of the water and from the land. The rain itself is explaining to the reader about its origin, work and its cyclic movement. A comparison has also been drawn between rain and music as both of them make the world more lively and return to their place of origin after fulfilling their purpose.

The Voice of The Rain Stanza Wise Explanation of The Poem

Stanza 1
And who art thou? said I to the soft-falling shower,
Which, strange to tell, gave me an answer, as here translated:
I am the Poem of Earth, said the voice of the rain,

Word Meanings:
thou – you
soft-falling – dropping softly
shower – raindrops when they fall continuously on Earth

Explanation: The poem begins with the poet asking for the identity of the soft-falling rain shower. Much to the surprise of the poet, the rain replies to his question which the poet translates for his readers. The rain in its own voice tells the poet that she is the poem of this Earth. The rain is trying to say that, as music or poetry gives pleasure to human beings, the rain gives happiness to mother Earth.

Stanza 2
Eternal I rise impalpable out of the land and the bottomless sea,
Upward, to heaven, whence, vaguely form’d, altogether changed, and
yet the same,

Word Meanings:
eternal – everlasting
impalpable – unable to be felt by touching
bottomless – very deep
upward – towards a higher level
whence – from where
vaguely – unclearly
form’d – made into a specific shape or form

Explanation: The poet says that the rain is an eternal process, but it takes different forms at different times. It rises from the land and the deep sea in the form of intangible water vapour and goes up to the sky. There it takes an indistinct shape in the form of clouds.

Although it changes in its form or shape, its core matter remains the same. Since vapour and clouds contain water they can get transformed into the other. The words ‘impalpable’ and ‘eternal’ indicate that nature is not fully understood and some part of it always remains beyond our reach.

Stanza 3
I – descend to lave the droughts, atomies, dust-layers of the globe,
And all that in them without me were seeds only, latent, unborn;

Word Meanings:
descend – move or fall downwards
lave – wash
droughts – dry spells
atomies – very tiny particles
globe – Earth
latent – dormant, inactive

Explanation: The raindrops pour down from above to wash away droughts and dust layers enveloping Earth. It satisfies the thirst of the dry Earth and heals everything that is degrading and is lying lifeless. The showers remove the dust particles and make Earth clean and green.
The rain also helps in the germination of seeds which were lying dormant due to a dry spell.

Stanza 4
“And forever, by day and night, I give back life to my own origin, And make pure and beautify it;
(For song, issuing from its birth-place, after fulfilment, wandering Reck’d or unreck’d, duly with love returns.)

Word Meanings:
origin – source
beautify – make beautiful
issuing – originating/starting
fulfilment – completing the cycle
wandering – moving from one place to another
reck’d – cared about
unreck’d – uncared for
duly – properly, rightly

Explanation: The rain is involved in a continued process of giving life on Earth by providing water to dormant seeds and making the Earth more beautiful and full of greenery. Rain helps in enhancing the beauty of Earth as, in the absence of water, everything turns dull or lifeless and dust accumulates everywhere.

The last two lines are the poet’s own words and his reflections upon the answers given by the rain. The poet observes that the life of rain is similar to that of a song. A song or poem is creativity at its best. It has the power to calm, heal, rejuvenate, transform and thrill. In the same way, repeated evaporation and condensation purifies the rain. The entire environment gets drenched in the rain, dust particles settle down and there is greenery everywhere which makes the whole Earth beautiful to look at. The poet therefore draws a parallel between rain and music as both have rhythm and ability to thrill. Both of them rejuvenate and beautify life.

The Voice of The Rain Poetic Devices Used in the Poem

Personification: The rain has been personified as it has been given a voice in the poem.

Metaphor: “I am the Poem of the Earth”. The poet uses a metaphor to compare how the rain leaves the ground to come back to the ground, giving back to it much like a person who leaves its home, only to come back after fulfilling its journey.

Parallelism/Simile: In the last two lines, the poet has drawn a parallel between the rain and the song of a poet.

Hyperbole: ‘Bottomless sea’ is an example of hyperbole. The poet describes sea as bottomless which is an exaggerated statement to bring out the desired effect.

Imagery: In the first line of the poem, ‘Soft-falling shower’ gives the reader an image of gentle rain or drizzle. During the dialogue between the poet and the rain, it creates an image of showers or drops of water falling down from the heavens to Earth and infusing it with greenery, purity and beauty.
