Question

What is simple harmonic motion

Answer 1

ocsillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position

Answer 2

A simple harmonic motion is a special type of periodic motion in which particle moves to and fro repeatedly about the mean position under a restoring force which is always directed towards the mean position and whose magnitude at any instant is directly proportional to the displacement of particle from the mean position at that instant.
