Overview

A simple pendulum consists of a mass hanging from a string. For small angles, its swing follows simple harmonic motion.

Fun Facts

"Earth's gravity varies slightly by location, affecting pendulum clocks (they slightly faster at the poles)."
"Galileo Galilei discovered the properties of pendulums by watching a chandelier swing in a cathedral."
"Foucault pendulums are used to demonstrate the rotation of the Earth."

Formula: T = 2π√(L/g)
