Question

define angular displacement, angular velocity and angular acceleration

Answer 1

The angular displacement is defined as the angle through which an object moves on a circular path. It is the angle, in radians, between the initial and final positions. (θf - θi) = angular displacement.

Answer 2

angular acceleration is the rate of change of angular velocity , angular velocity is defined as the rate of change of angular position of a rotating body, angular displacement is defined as the angle through which an object moves on a circular path
