Question

Define Angular Velocity. What are its units?

Answer 1

Angular velocity of a rotating body is defined as the amount of angle rotated (or angular displacement) by the body in unit time. It is denoted by omega $\left(\omega \right)$.

Mathematically, angular velocity, $\omega =\frac{d\theta }{dt}$ $rad/s$

It's SI unit is radian per second.
