Pendulum Motion and Period

A simple pendulum is a small ball, or bob, hanging from a string that has negligible mass and does not stretch. Pendulums appear in everyday life, including clocks, swing sets, and a sinker on a fishing line. Their motion is a useful model for studying repeating movement.

An idealized model of a point mass suspended from a non-elastic and massless string is known as a simple pendulum.

Consider a top, freely suspended from a string fixed to a pivot point. It experiences a gravitational force and tension in the string. At the equilibrium position, both these forces balance each other.

When the top is ...
