This page features an animated roller coaster with two loops. Energy bar graphs show the transformation of energy from potential to kinetic as the roller coaster descends the initial hill. As the car continues on the track, users can visualize how kinetic energy is dependent upon an object's mass and its speed. This animation is an example of a system in which TME (Total Mechanical Energy) remains the same during the course of the motion. It is part of The Physics Classroom, a collection of online tutorials for high school physics students.

This item is an animation of a skier descending a slope and encountering the force of friction at the end of the run. It contains four energy bar graphs depicting KE, PE, Work, and TME (Total Mechanical Energy). It differs from the Roller Coaster animation in that it illustrates a system where TME is lost due to friction.
