Circular Motion

Key Questions

  • It depends what information you begin with.

    1. If frequency is known: T=1/f
    2. If speed is known: T=(2πr)/v
    3. If angular frequency is known: T=(2π)/ω
    4. If you know the centripetal force, object's mass and radius of motion: Use F=(mv^2)/r to find v then use T=(2πr)/v
    5. If you know the centripetal acceleration and radius of motion: Use a=(v^2)/r to find v then use T=(2πr)/v
