What Happens When Earth Turns Under a Pendulum?

BEHIND THE WORK

Why does a Foucault pendulum's path appear to turn?

The pendulum keeps nearly the same swing plane while Earth rotates beneath it. In this time-compressed overhead model, A cos(ωt) supplies the fast back-and-forth swing and Ω = ΩEarth sin φ supplies the much slower precession. The display uses ω:Ω = 29:1 so the effect is visible in seconds.
