PURPOSE: To model the Foucault pendulum.
DESCRIPTION: The circular base can be rotated while the pendulum oscillates in a fixed plane in the frame of reference of the laboratory, thus showing the apparent rotation of the plane of the pendulum when viewed in the frame of reference of its base.
SUGGESTIONS: This can also be done more slowly in the lecture halls using the rotating stage as the rotating reference frame.
REFERENCES: (PIRA 1E20.20) See Demonstration Reference File for a number of articles dealing with the theory of the Foucault pendulum and how to make them.
EQUIPMENT: Pendulum suspended from rotating table.
SETUP TIME: None.
