It depends what information you begin with.
- If frequency is known:
T=1/f - If speed is known:
T=(2πr)/v - If angular frequency is known:
T=(2π)/ω - If you know the centripetal force, object's mass and radius of motion: Use
F=(mv^2)/r to findv then useT=(2πr)/v - If you know the centripetal acceleration and radius of motion: Use
a=(v^2)/r to findv then useT=(2πr)/v
