Formula Uniform Circular Motion Velocity Angular velocity Radius
$$\class{blue}{v} ~=~ r \, \class{red}{\omega}$$ $$\class{blue}{v} ~=~ r \, \class{red}{\omega}$$ $$\class{red}{\omega} ~=~ \frac{\class{blue}{v}}{r}$$ $$r ~=~ \frac{\class{blue}{v}}{\class{red}{\omega}}$$
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
$$ \class{red}{\omega} $$ 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.
