# Angular Velocity

Written by Jerry Ratzlaff. Posted in Properties

Angular velocity is how quickly an object moves through an angle.

## formula

$$v_a = \frac { A_f \;-\; A_i } { t }$$

$$v_a = \frac { \Delta A } { t }$$

Where:

$$v_a$$ = angular velocity

$$A_f$$ = final angle

$$A_i$$ = initial angle

$$t$$ = time

$$\Delta A$$ = angle differential $$(A_f \;-\; A_i)$$
