    How much energy is given out by one man?
    If he applied a F on a object, friction is f, distance is s.
    What's the energy given out by him?

    What do you mean by "energy given out"? Is that the same as "work done"?

    I suppose that they are not the same.
    As a man is still releasing energy when he is moving a box even the box is still stationary.

    work done by the man= energy release by the man
    the term is different but the meaning is the same.....
