The Pendulum

A pendulum is a weight, called a bob, attached to a string or rod that swings back and forth around a fixed point. When displaced from its resting position, gravity pulls it back, causing it to swing in a regular, repetitive motion called oscillation. The motion depends on factors like the length of the string and gravity. Pendulums are used in clocks for precise timekeeping because their swings are consistent, and they demonstrate fundamental principles of motion and energy transfer between potential and kinetic energy.
