Young scholars build a device to protect an egg and prevent it from breaking when dropped.

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

Meet Carlos at his Mexican diner, and he will tell all about energy and energy transformations.

Build the roller coaster, then keep making adjustments to see how it affects the potential and kinetic energy of the marble along its tracks.

[Free Registration/Login may be required to access all resource tools.] Decribes how energy changes from one form to another and energy changes between kinetic and potential energy.

This tutorial helps students understand the Kinetic Theory, which explains the effects of temperature and pressure on matter as it goes through phase changes.

Step-by-step illustrated instructions showing how to drop four eggs into four cups without touching them. Demonstrates the concept of inertia according to Newton's first law of motion.

Explains what kinetic and potential energy are and how they differ.
