Chapter: Problem:
  • Step 1 of 1

    Ball A has stopped moving while reaching at the ground. According to the law of conservation of energy that energy must be conserved. Part of energy of ball A is transferred to ball B, causing it to be raised to a higher final position. The remaining energy of the ball A is lost to the surface of the hill as heat. This is because when ball A rolls down the hill, some of its kinetic energy is transferred to the surface of the hill as heat. This transfer of heat is called frictional heating. Thus the energy stored in ball A in its original position (potential energy) is distributed to ball B through work and to the surface of the hill by heat.
