Question

What is simple pendulum ?

Answer 1

A simple pendulum consists of a small metal ball (called bob) suspended by a long thread from a rigid support, such that the bob is free to swing back and forth. A pendulum completes every swing (or every oscillation) in exactly the same time, provided its length is kept constant.

Answer 2

Answer:

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
