 The Physics Classroom: Which Path Requires the Most Energy? Created by Tom Henderson of Physics Classroom.com, this page features animations of carts traveling at constant speed on three inclines of equal distance but varying slopes. Students can observe how the variables of force and displacement affect the amount of work done by each cart. The question for students to consider is which path requires the most energy. This item is part of The Physics... http://www.physicsclassroom.com/mmedia/energy/au.cfm
 The Physics Classroom: Energy Transformation for Downhill Skiing Created by Tom Henderson of Physics Classroom.com, this page features an animation of a skiier descending down a 58-meter slope. The first part of the animation depicts the changing ratio of potential-to-kinetic energy. At the end of the run, the skiier encounters unpacked snow and loses total mechanical energy to the dissipative force of friction. Bar graphs for W (Work) and TME (Total... http://www.physicsclassroom.com/mmedia/energy/se.cfm
 The Physics Classroom: Energy Transformation for a Pendulum Created by Tom Henderson of Physics Classroom.com, this page is an animated tutorial featuring a simple pendulum attached to a pivot point by a string. The pendulum motion is accompanied by corresponding energy bar graphs for kinetic and potential energy. It is intended to allow users to visualize mechanical energy conservation, as they investigate why the tension force does no work on the... http://www.physicsclassroom.com/mmedia/energy/pe.cfm
 Infrared: More Than Your Eyes Can See The electromagnetic spectrum, spanning energies and wavelengths from radio waves to gamma rays, encompasses all forms of light. Infrared radiation, located in the range just beyond visible light, is emitted by all matter and is very useful in gathering data about Earth and space. In this video segment adapted from NASA by WGBH's Teachers' Domain project, visitors can learn about infrared... http://www.pbslearningmedia.org/resource/ess05.sci.ess.earth...
 Movement of Energy Crossword Puzzle This crossword puzzle features questions on how energy moves. It would be most useful for students with some knowledge of energy transfer, propagation, and travel. An answer key is provided.
