Give two examples of periodic motion.

Periodic motion:

A motion that is regular and repeating is referred to as a periodic motion. If the motion of a moving object is repeating itself after a certain time then the motion of the object is a periodic motion. The Interval of time taken to complete each cycle of motion is called the time period of the periodic motion. Periodic motion can be used to measure time. Periodic means "repeating after a certain time interval".
