Oscillatory motion and vibration

simple pendulum

A particularly interesting periodic motion in the field of mechanics is that an object which moves from its equilibrium position and returns to performing a movement back and forth with respect to this position.

This type of periodic motion is called oscillatory motion. Oscillations of a mass connected to a spring, the movement of a pendulum or the vibrations of a string instrument are examples of oscillating movements. The equilibrium position is often defined as the position at rest.
