The period T of an object in circular motion is the time taken for the object to make one complete revolution.
- Unit: s (seconds)
The frequency f of an object in circular motion is the number of complete revolutions made by the object per unit time.
- Unit: s-1 or Hz (hertz)
$T = \frac{1}{f}$
Other useful equations:
$\omega = \frac{2 \pi}{T}$
$\omega = 2 \pi f$
$v =r \omega$ , where v is the linear velocity
