Question

What is the work being done on?what is happening to the object? Who (what) is doing the work?

Answer 1

Work and energy. Whenever a force is applied to an object, causing the object to move, work isdone by the force. ... If you pick the book up and place it gently back on the floor again, though, you're doing negative work, because the book isgoing down but you're exerting an upward force, acting against gravity.
