A ball rolling down a hill would have the greatest kinetic energy. It helps the ball to keep moving down the hill despite all the forces trying to stop it. The energy comes from the forces trying to stop it. The energy comes from the force of gravity, as the object rolls down the hill. If there were an absence of gravity, the object would not fall. When the ball is rolling down the hill, it has kinetic energy. The kinetic energy or driving force of an object is the power it possesses due to its momentum.
