How does the energy of an object change when it perform work?

1.	How does the energy of an object change when it perform work?
Answer» TION:When work is done on a system or object, ENERGY is added to it. When work is done by a system or object, it GIVES some of its energy to something else. ... By applying a force on the ball over this distance, the hand is doing work on the ball, and the ball gains kinetic energy. This is what gives it speed.
