Circular Motion
Key Questions

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 find#v# then use#T=(2πr)/v#  If you know the centripetal acceleration and radius of motion: Use
#a=(v^2)/r# to find#v# then use#T=(2πr)/v#
 If frequency is known:
