A ball is dropped from the roof of a building. Points A, B, C, and D in the diagram represent positions of the ball as it falls. At which position will the ball have the greatest kinetic energy?
There are 2 types of energies going into play when dropping something, potential energy and kinetic energy. potential energy is the height of the object before it is dropped. The ball has the most kinetic energy right before it hits the ground, then releases it when it does hit the ground.
