Kenetic Energy

A. The energy that moves a vehicle is called kinetic energy. A moving vehicle encounters resistance that depletes its kinetic energy. Such a resistance includes friction created by the vehicle's tires rolling against the pavement and by the vehicle's body moving through the atmosphere.

B. Wind resistance and tire friction, however, will only slow a vehicle gradually. A modern brake system can bring a vehicle to an abrupt stop by rapidly converting a vehicle's kinetic energy into heat and then dissipating it.
