This site is from the Physics Department at Georgia State University. The reliance upon the law of conservation of energy as an approach to problem-solving is presented and encouraged. It is modeled through a problem involving a...

Fourth graders use a toy to make observations that speed is related to the amount of energy in an object as well as work with gravitational and elastic potential energy.

Demonstrates how principles of kinetic energy, potential energy and energy conservation can be used to determine the speed of a descending object if given its initial height. Further discussion of other topics such as heat and...

An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...
