Energy Transformation for Downhill Skiing
Downhill skiing is a typical describe of the relationship among work and energy. The skier starts at an elevated position, therefore possessing a huge quantity of potential energy that is energy of vertical position. If beginning from rest, the mechanical energy of the skier is whole in the form of potential energy. As the skier starts the descent down the hill, potential energy is lost and kinetic energy that is energy of motion is gained. As the skier loses height (and therefore loses potential energy), she gains speed and thus gains kinetic energy. Once the skier reaches the bottom of the hill, her height reaches a value of 0 meters and denoting a total depletion of her potential energy. At this point, her kinetic and speed energy have reach a maximum.
