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#
