A point mass suspended from a mass less spring or placed on a frictionless horizontal plane attached with spring (fig.) constitutes a linear harmonic spring pendulum
An ideal simple pendulum consists of a heavy point mass body suspended by a weightless, inextensible and perfectly flexible string from a rigid support about which it is free
Harmonic oscillation is the repetitive movement of an object or system about a fixed point or equilibrium position in response to a restoring force. It is a type of periodic motion that can be modeled mathematically as a sinusoidal function. Examples of harmonic oscillation include a pendulum swi

Oscillatory or vibratory motion is that motion in which a body moves to and fro or back and forth repeatedly about a fixed point in a definite interval of time. In such a moti
(1) Time period : It is the least interval of time after which the periodic motion of a body repeats itself.

Simple harmonic motion is a special type of periodic motion, in which a particle moves to and fro repeatedly about a mean position under a restoring force which is always dire
Velocity of the particle executing S.H.M. at any instant, is defined as the time rate of change of its displacement at that instant.
In case of S.H.M. when motion i
The acceleration of the particle executing S.H.M. at any instant, is defined as the rate of change of its velocity at that instant. So acceleration
