First off, remember that the pendulum only demonstrates rotational motion about the earth's axis. If the pendulum were built directly over the North Pole, it would seem to rotate 360 degrees every 24 hours. However, at the equator, a pendulum would not seem to rotate at all. That is because it is only undergoing lateral motion.
So what about places in between?
The rotation demonstrated by the pendulum can be predicted by the following formula: n=360sinF, where F is the angle of a place from the equator.
For example, in Paris the latitude is about 48.6 degrees,
so Foucault's
pendulum "rotated" about 270 degrees.
In Atlanta, the latitude is about 33.75 degrees, so a
pendulum
would seem to rotate about 200 degrees in 24 hours.
