Question

what is a simple pendulum​

Answer 1

Explanation:

A pendulum is a body suspended from a fixed support so that it swings freely back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

A simple pendulum is a heavy point mass suspended from a rigid support by a massless and inextensible string.
