Description: Animation of a fictitious pendulum of Foucault of 67 meters released at a distance of 50,25 meters (3/4 its length) in the east with a null speed. The rotation of the Earth is also exaggerated and corresponds to a rotation in 110 seconds. It corresponds to the view taken from the plane of oscillations: the terrestrial reference frame thus turns. But the shadow of a stick added at the center for ease of comprehension, rotates faster than the plane of oscillations. In this pseudo plan, the trace is not linear but corresponds to an ellipse. In this illustration, the pendulum is launched at noon at equinox. Thus the sun set is exactly six hours after the launch. Source of the Gnuplot animation is provided (GPL)
