Answer 1

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

Answer 2

Answer:

Definition

(SHM) is defined Linear simple harmonic

as the linear periodic motion motion ofa

body, in which the force (or acceleration) is always

directed towards the mean position and its magni-

tude is proportional to the displacement from the

mean position.

OR

A particle is said to execute linear SHM if the

particle undergoes oscillations about a point of

stable equilibrium, subject to a linear restoring force

always directed towards that point and whose

magnitude is proportional to the magnitude of the

displacement of the particle from that point.

Examples : The vibrations of the tines (prongs) of a

tuning fork, the oscillations of the needle of a

sewing machine.
