Energy of motion is the energy an object possesses due to its motion, which is also called kinetic energy. This means that the object, which has energy of motion, can do work on any object it hits.
The work that an object does with its kinetic energy can vary depending on the object and what it is connecting with. An everyday example of this energy is a bouncing ball. The person bouncing the ball has to exert enough force to get the ball to bounce against the gravitational pull. That force, at this point, is the building of potential energy. This potential energy buildup is all classified as doing work on an object.
Once the ball is released, the potential energy changes to kinetic energy, before the ball hits the ground, because the ball is now in motion. The actual output of energy occurs once the ball hits the ground. At that point, the ball is doing work against the ground, which causes the ball to bounce back up into the air, although the amount of energy is now decreased, and the cycle starts over, until the ball is caught or otherwise stops bouncing.
