Question

what is a simple pendulum explain how it performs an oscillatory motion​

Answer 1

Answer:

Definition of simple pendulum. : an ideal pendulum consisting of a point mass suspended by a weightless inextensible perfectly flexible thread and free to vibrate without friction

Explanation:

pendulum is a weight suspended from a pivot so that it can swing freely. ... When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period

Answer 2

Answer:

A simple pendulum is a simple size metallic bob which is suspended by a light string from a fixed point.

This to and fro motion is called oscillatiory motion
