# Scalars and Vectors in Physics | Definition, Types – Scalars and Vectors

Scalars:
Those physical quantities which require only magnitude but no direction for their complete representation are called scalars.

Distance, speed, work, mass, density etc are the examples of scalars. Scalars can be added, subtracted, multiplied or divided by simple algebraic laws.

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

### Scalars and Vectors Difference

Vectors:
Those physical quantities which require magnitude as well as direction for their complete representation and follows vector laws are called vectors.

Vectors can be mainly classified into following two types
1. Polar Vectors:
These vectors have a starting point or a point of application such as displacement, force etc.

2. Axial Vectors:
These vectors represent rotational effect and act along the axis of rotation in accordance with right hand screw rule, such as angular velocity, torque, angular momentum etc.
