Physical Pendulum

When a rigid body is hanging freely from a fixed pivot point and is displaced, it oscillates similar to a simple pendulum and is known as a physical pendulum. The period and angular frequency of a physical pendulum are obtained by using the small-angle approximation and drawing parallels with a spring-mass system. The small-angle approximation (...

Consider a watering can hanging from a hook. When displaced from its pivot point, it oscillates similar to a simple pendulum. The watering can is an example of a physical pendulum.

It can be modeled as its entire weight acting at its center of mass, which oscillates about the pivot point. Let the distance between the pivot point and the c...
