The law of conservation of energy and describe the energy transformation that occur as you coast down a long hill on a bicycle and then apply the brakes to make the bike stop bottom

As you coast down a long hill on your bicycle, potential energy from your height is converted to kinetic energy as you and your bike are pulled downward by gravity along the slope of the hill.
