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 \( \frac{\text{rad}}{\text s} \) 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.
