This interactive tutorial provides a simple explanation of the Foucault Pendulum, a device constructed in 1851 by French physicist Jean Foucault to demonstrate the rotation of the earth. This resource features videos of a Foucault pendulum in Australia (one of the few that exist in the Southern hemisphere). Accompanying animations help the user visualize the line of swing from different frames of reference.

9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.
4G. Forces of Nature
6-8: 4G/M2. The sun's gravitational pull holds the earth and other planets in their orbits, just as the planets' gravitational pull keeps their moons in orbit around them.
10. Historical Perspectives
10B. Uniting the Heavens and Earth
9-12: 10B/H1. Isaac Newton, building on earlier descriptions of motion by Galileo, Kepler, and others, created a unified view of force and motion in which motion everywhere in the universe can be explained by the same few rules. Newton's system was based on the concepts of mass, force, and acceleration; his three laws of motion relating them; and a physical law stating that the force of gravity between any two objects in the universe depends only upon their masses and the distance between them.
9-12: 10B/H3. The Newtonian system made it possible to account for such diverse phenomena as tides, the orbits of planets and moons, the motion of falling objects, and the earth's equatorial bulge.
