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.
Apr 5, 2024 · pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.

- What are pendulums used for?Different types of pendulums have different applications. Examples of simple pendulums are found in clocks, swing sets, and even the natural mechan...
- How are pendulum clocks powered?Pendulum clocks are powered by mechanisms that trigger the pendulum to swing with a constant period. Traditionally, weight or spring mechanisms ful...
- When was the pendulum clock invented?Some authorities ascribe the invention of the pendulum clock to Galileo, while others credit Christiaan Huygens. This disagreement arises because G...
Sep 12, 2022 · The Simple Pendulum. 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 15.5.1 15.5. 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 mass suspended from a pivot point that is free to swing back and forth. Because the motion is oscillatory (a fancy way to say back and forth) and periodic (repeating with a characteristic time), pendulums have been used in clocks since the 17th century.
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 towards the equilibrium position.
David explains how a pendulum can be treated as a simple harmonic oscillator, and then explains what affects, as well as what does not affect, the period of a pendulum. Created by David SantoPietro .

Key terms. Equations. How can we find frequency? Analyzing the forces on a simple pendulum. An object is a simple harmonic oscillator when the restoring force is directly proportional to displacement. Figure 1: A simple pendulum with length l , mass m , and displacement angle θ has a net restoring force of − m g sin. θ .
