This site from the Exploratorium provides a demonstration, using everyday materials, of the energy exchange between two coupled pendulums. The site provides a thorough description of how the two pendulums interact and...

This site, from UCLA's Department of Physics, contains web and in-class demonstrations of physics concepts in the topic areas of mechanics, harmonic motion and waves, electricity and magnetism, acoustics, optics, matter...

This web site is a basic, non-mathematical introduction to relativity. It covers concepts from Galileo, Newton, and Maxwell through Einstein and special relativity. The site also mentions modern topics such as the...

This resource illustrates classical energy diagrams for 1D motion. It simulates an experiment where the energy of a cart with a magnet can be changed by putting magnets along a track. The resultant potential and...

This paper, presented at the 2002 Physics Education Research conference, describes a study conducted to investigate small-group discussions in an inquiry-based middle school science classroom in order to determine the...
