Formula Uniform Circular Motion Velocity Angular velocity Radius
$$v ~=~ r \, \omega$$ $$v ~=~ r \, \omega$$ $$\omega ~=~ \frac{v}{r}$$ $$r ~=~ \frac{v}{\omega}$$
Velocity
$$ v $$ Unit $$ \frac{\mathrm m}{\mathrm s} $$ Orbital velocity of the body on the circular path at a certain distance from the axis of rotation.
Angular velocity
$$ \omega $$ Unit $$ \frac{\mathrm{rad}}{\mathrm s} $$ Angular velocity is the change of the angle per second. The greater the angular velocity, the faster the body rotates (greater orbital velocity).
Radius
$$ r $$ Unit $$ \mathrm{m} $$ Radius of the circular path. The further away the body is from the axis of rotation (larger radius), the faster the body rotates.
