### Velocity

The distance moved by a rigid body per unit time in a given direction, is t velocity of that body.

Def. The rate of displacement of a body in respect of time and a specific direction is known as velocity of that body.

Let, the displacement of the body is s in a unit time t, and velocity is v

### Kinds of velocity

Velocity is four types

1. Uniform velocity: When a body travels in a straight line (in a particular direction) and cover equal distance in equal interval of time, it is said to have uniform velocity.
2. Non-uniform Velocity: When a body travels in a straight line (in a particular direction) and cover un-equal distance in equal interval of time, it is said to have uniform velocity.
3. Instantaneous velocity: The velocity of a body at any particular instant during its motion is called instantaneous velocity.
4. Average velocity: If the velocity of the body in a particular direction changes continuously at a uniform rate, then the arithmetic mean of the initial and the final velocities over a given period of time is called the average velocity in that direction.
