Uniform Circular Motion
Object travels in a circular path at constant speed
Distance around the circle is its circumference
Average speed formula from kinematics still applies
Frequency is the number of revolutions or cycles which occur each second
Symbol is f
Units are 1/s, or Hertz (Hz)
Period is the time it takes for one complete revolution, or cycle.
Symbol is T
Unites are seconds (s)
T = time for 1 cycle = time for 1 revolution
Frequency and Period
Is an object undergoing UCM accelerating?
Magnitude of Centripetal Acceleration
If an object is traveling in a circle it is accelerating toward the center of the circle
For an object to accelerate, there must be a net force
