Applying the Coriolis Effect to the Foucault Pendulum.

This article discusses the application of the Coriolis effect to the Foucault pendulum. The Foucault pendulum swings back and forth in a fixed vertical plane while the Earth rotates beneath it. The rotation of the Earth causes the pendulum to appear to precess clockwise when viewed from a rotating-frame perspective. The paper explains how the Coriolis effect causes this precession. The article also discusses the different motions of the pendulum and how each contributes to the Coriolis effect deflection. The total deflection per cycle is four times the amount given by a specific equation, and the time for the pendulum to precess 360° is determined by the latitude of its location. The article concludes by stating that the rotating-frame analysis and the nonrotating-frame analysis yield the same result when applying the Coriolis effect to the Foucault pendulum.
