A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] . 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.

Sep 12, 2022 · A simple pendulum is defined to have a point mass, also known as the pendulum bob, which is suspended from a string of length L with negligible mass (Figure \(\PageIndex{1}\)). Here, the only forces acting on the bob are the force of gravity (i.e., the weight of the bob) and tension from the string.
A pendulum is a body suspended from a fixed support such that it freely swings 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 towards the equilibrium position.
