It is the type of motion that repeats itself after certain intervals of time.

A motion where an object moves along a circular path about a fixed axis is called Rotational Motion.

Any object will remain in its existing state of motion or rest unless a net external force acts on it.

Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction.

It is the type of motion which is repetitive within a time frame. If it is mechanical it is called vibration.
