Question

A ball is dropped from a certain height onto floor and keeps bouncing.Is the motion of ball simple harmonic?Explain.

Answer 1

Answer:

Explanation:As the ball is dropped from certain height  onto the floor having initial potential energy and keeps bouncing. It is observed after each bounce its height and its P.E are decreasing. And time period is also decreasing. As time period is not constant and total energy is not conserved so the motion of ball is not simple harmonic motion.
