Foucault Pendulum (WebGL)





Foucault’s pendulum is a device invented by French scientist Leon Foucault to prove the Earth’s rotation in 1851. The fact that the Earth rotates has been known for a long time, but it is the first example that proves it by experiments.

Foucault’s pendulum is a freely swinging pendulum whose path appears to change predictably, thus providing evidence for Earth’s rotation.
