# Angular Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Angular velocity (or angular speed) 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

$$\Delta A$$ = angle differential

$$t$$ = time
