Oscillatory Motion ( Waves & Oscillation )


"The motion of a body about its mean position is known as oscillator (or) vibratory motion"

Simple Harmonic Oscillator:
It is a type of oscillator in which the restoring force is directly proportional to the displacement. i,e
In Eq.1 ' k ' is constant and the negative sign shows that the body is always directed towards the mean position.
Now from the Newton 2nd Law, we have




Eq(8) represents the equation of simple Harmonic Oscillator
(SHO).
