Pendulum - Wikipedia

A pendulum is a weight suspended from a pivot so that it can swing freely. 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. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, …

Impact energy is a measure of the work done to fracture a test specimen. When the striker impacts the specimen, the specimen will absorb energy until it yields. At this point, the specimen will begin to undergo plastic deformation at the notch. The test specimen continues to absorb energy and work hardens at the plastic zone at the notch.

Period of simple pendulum and the laws of simple pendulum

Where l = Length of a simple pendulum, g = acceleration due to gravity. From the above expression, we can have the following conclusions. Law of Mass: As the expression doesn't contain the term 'm', the time period of the simple pendulum is independent of the mass and material of the bob.This property is known as the law of mass. Law of Length: The time …

What Is Pendulum Physics? (with picture)

When a pendulum is swinging, its energy state changes based on where in the arc the bob is, but what remains the same is the sum total of the bob's potential and kinetic energy — in other words, the energy is conserved. At the pendulum's highest point, it has no speed and all the energy in the system is potential.
