Question

Can a motion be periodic and not simple harmonic? If your answer is yes, give an example and if not, explain why?

Answer 1

Periodic motion, in physics, motionrepeated in equal intervals of time. ... Simple harmonic motion is a special case of periodic motion. In the examples given above, the rocking chair, the tuning fork, the swing, and the water wave execute simpleharmonic motion, but the bouncing ball and the Earth in its orbit do not.
