Question

What is simple harmonic motion
give two examples

Answer 1

Ex1- Swing

Swings that we see in the park is an example of simple harmonic motion

Ex2- Hearing

The process of hearing is is impossible without simple harmonic motion. The sound waves that enter our ear causes the eardrum to vibrate back and forth

Bonus Ex- cradle

The back and forth movement of the cradle caused due to a single push and is maintained by the principle of SHM, and hence, caused the baby to sleep.

Hope it helps

Answer 2

S.H.M:- If the acceleration of the vibrating body directly varies with the displacement of the body from the mean position and always directed to the mean position, the motion of that body is called simple harmonic motion.

Ex:- (i) The motion of a pendulum is an S.H.M.

(ii) The motion of vibrating mass attached to a spring is an S.H.M.
