What is periodic motion?

Periodic Motion :–

This is a type of motion where the object repeats its motion after a fixed interval of time.

Examples: pendulum of a clock, motion of child on a swing etc.

Periodic motion is a type of motion that is being performed. You can take a rocking chair, bouncing ball, and a swing as an example of periodic motion.

Periodic motion is just another word for the motion because it describes any type of object performing movements even an object vibrating is another great example of periodic motion. If you want to talk about the motion of the universe take Earth and the moon orbiting around the sun it is an object performing.

Hope this helped :)
