→ Oscillatory Motion
The to and fro motion of an object that repeats after a particular period of time is known as oscillatory motion. It is also known as periodic motion as this kind of motion repeats after a particular period of time.
Some common examples of oscillatory motion are:
✳ Motion of the hammer of an electric bell.
✳ Motion of your hands while running.
✳ Motion of a child on a see-saw.
✳ Motion of a simple pendulum.
✳ Motion of a spring.
