How a Simple Pendulum Proved the Earth Rotates

Foucault pendulum Earth rotation physics

Quick Look

In 1851, Léon Foucault demonstrated Earth's rotation with a simple pendulum.
By suspending a heavy bob from a long wire, he showed that the pendulum's swing plane appeared to rotate due to the Earth moving beneath it, providing tangible evidence of planetary motion.
