Question

Define angular velocity and angular acceleration.

Answer 1

Angular velocity: The rate of change of angular position of a rotating body.

Angular Acceleration: Angular Acceleration is the time rate of change of angular velocity. In three dimensions, It is a pseudovector. In SI units, it is measured in radians per second squared, and is usually denoted by the Greek letter alpha.
