Circular Motion

Key Questions

• Question #2555d

  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#
