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 Mechanical Energy) illustrate the relationship between work and mechanical energy. This activity contains a full text discussion of each process as it occurs. It is part of The Physics Classroom, a comprehensive online tutorial written for high school physics students.

This item is an animation of a roller coaster with two loops. It contains energy bar graphs depicting KE, PE, and total mechanical energy (TME). It is closely related to the Downhill Skier animation in depicting potential-to-kinetic energy, but differs in that it illustrates a system where TME remains the same throughout.
