Periodic Motion
When a body repeats its motion continuously on a definite path in a definite interval 
of time then its motion is called periodic motion and the interval of time is called 
time period T.

Periodic Motion
When a body repeats its motion continuously on a definite path in a definite interval 
of time then its motion is called periodic motion and the interval of time is called 
time period T.
Oscillatory motion
If a body in periodic motion moves along the same path to and fro about a definite 
point (equilibrium position), then the motion of the body is a vibratory motion or 
oscillatory motion
Note: Resultant force acting on the particle is zero in equilibrium condition.

Simple harmonic motion (S.H.M.)
Simple Harmonic Motion is the simplest form of vibratory or oscillatory motion.
Where ‘y’ is displacement of the particle from the mean position

Necessary Condition to execute S.H.M. (continued)
(a) Motion of particle should be periodic oscillatory
(b) Total mechanical energy of particle should be conserved. KE + PE = constant
