The to and fro motion of a body about it's mean position is known as ocillatory motion .
The back and forth motion of a body about it's equilibrium position is known as ocillatory motion.
Explanation
The oscillatory Motion is also known as vibratory motion. If a body moves back and forth over the same path, then such motion of the body is known as ocillatory motion .
Examples
The example of oscillatory Motion are given below
1. Motion of simple pendulum
2. Motion of wires of sitar and violin
3. Motion of a body attached to an elastic spring
