Which of the following is not an example of approximate simple harmonic motion? A. a ball bouncing on the floor

B. swinging chandeliers

C. oscillations of air molecules that transmit sound

D. oscillations of electrons in the antennas of radio and TV transmitters

Answer to this question is (A)

Explanation

A ball bouncing on the floor is not the example of simple harmonic motion. SHM is the special kind of to and fro motion in which a particle oscillate about its mean position in a straight line. The acceleration of the particle is always directed towards its mean position and is directly proportional to its displacement from its mean position.

In case of a ball bouncing on the ground, the motion of the ball is not SHM, as neither it's a to and fro motion nor the acceleration is proportional to its displacement from its mean position.
