## Circular Velocity

Circular velocity is the velocity at which an object must move in order to keep a specific radius.

### Circular Velocity formula

$$v_c = \frac { 2 \pi r } { t }$$

Where:

$$v_c$$ = circular velocity

$$r$$ = radius

$$t$$ = time

Solve for:

$$r = \frac { v_c t } { 2 \pi }$$

$$t = \frac { 2 \pi r } { v_c }$$
