Question

note on simple harmonic motion ​

Answer 1

simple harmonic motion

A particle executes simple harmonic motion if it moves to and fro about a mean position and direction of restoring force which is directly proportional to displacement from the mean position and solve that it was a mean position.

i hope it helps you

Answer 2

Answer:

it is a special type periodic motion or oscillation where the restoring force is directly proportional to displacement and which acts in the direction opposite to that of displacement
