... As the skier is at the top of his path, we calculate the potential energy to be 50,000 Joules. As the skier begins to move down the mountain, the potential energy converts into kinetic energy. The energy always equals 50,000 J. At the bottom of the skier’s path, the kinetic energy is now equal to th ...

Regenerative brake
A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to heat by friction in the brakes and therefore wasted. In addition to improving the overall efficiency of the vehicle, regeneration can also greatly extend the life of the braking system as its parts do not wear as quickly.
