Absolute Rotation of the Foucault Pendulum

Authors: Russell p. Patera

The absolute rotations of the Foucault Pendulum and its mounting fixture were derived for any latitude and Earth rotation angle. A theorem in attitude kinematics was used to obtain analytical solutions for both rotation angles and rotation angle rates. Both pendulum and mounting fixture were found to have absolute rotation rates in the counterclockwise direction in the Northern Hemisphere. The difference in rotation rates is in agreement with the observed relative clockwise precession rate of the pendulum with respect to its mounting fixture in the local Earth reference frame. The results were validated with an alternative kinematic method.
