ASU Now - Quiz - Foucault Pendulum

Download

TEMPE - Mar. 9, 2016 - ASU Now - Quiz - Foucault Pendulum - Where is it? The Foucault Pendulum demonstrates the rotation of the earth. As the pendulum ball swings back and forth, the plane of its swing appears to slowly rotate in a clockwise direction. Actually, the path of the pendulum is fixed in space, and it is the earth, and pendulum pit, that slowly turns beneath the ball. If the pendulum were located at the North Pole, it would take 24 hours to rotate through 360 degrees; at the equator, it would not rotate at all. In the Bateman Physical Science Building, F-Wing, it takes 43 hours and 34 minutes for a complete rotation. The length of the cable is 21.5 meters (about six-stories tall), and the mass of the ball is 108 kilograms. It takes the ball about 9.3 seconds to go approximately 3.6 meters.
