The rate of change of displacement is known as the velocity or linear velocity.

If the linear position of a particle or a body is changed from initial position $O$ to final position $F$, then $OF=Î”r$ is the displacement.

The $Î”r$ must have taken some time, let $Î”t$, then the velocity $v$ will be

The velocity is also known as the average velocity.

The rate of displacement in very small time or in the negligible time is known as the instantaneous velocity.

The instantaneous velocity is also known as the velocity.

The angular velocity in rotational motion is analogous to the linear velocity in the linear motion.

We shall have the introduction with the angular velocity.

The angular velocity is the rate of change of angle.

The angular velocity is also known as the average angular velocity.

Similar to the instantaneous linear velocity, the instantaneous angular velocity is the change of angle in a very small time. The time is so small that we can not think about a smaller number.

When we observe the rate of change in the angle in negligible time, such an angular velocity is instantaneous angular velocity.

The instantaneous angular velocity is known as the angular velocity.

The instantaneous angular velocity is given above.

The direction of angular velocity is given by the right-hand thumb rule.

The angular velocity for Anticlockwise rotation of a body is positive, and for a clockwise rotation, it is negative.
