What is the period of a motion?
Consider how often something happens, like heartbeat intervals.

Reciprocal means one is the inverse of the other.
True or False: All periodic motions are also oscillatory.
Think about examples like a full rotation which is periodic but not oscillatory.
A pendulum has a length of 2 meters. Calculate the period of the pendulum's swing.
Remember the formula for the period of a pendulum.
Describe the effects of damping on an oscillatory motion of a spring. How does it affect period and amplitude?
Think about how a car's shock absorbers slow down oscillations.
