The to and Pro motion of a simple pendulum is an example of a periodic or an oscillatory motion is called pendulum.
A weight that is suspended from a pivot and allowed to freely swing is known as a pendulum. When a simple pendulum is sideways moved from its resting, equilibrium position, gravity exerts a restoring force that accelerates the pendulum back toward the equilibrium position. The pendulum oscillates about the equilibrium position and swings back and forth when the restoring force acting on the mass is withdrawn. The period is the duration of one full cycle, which consists of a left swing and a right swing. The length of the pendulum and, to a lesser extent, its amplitude—the width of its swing—have an impact on the period.
