I do the same work on raising and lowering the weight. My thought was that since a work is done to raise it up a distance x and then bring it down a distance x it should be doubled, however my father said that the displacement is overall 0 so the work it did was zero but I still can't understand...

Why is this so?

If i lift it a distance x then bring it back down, so that the displacement is 0 but distance traveled is 2x. Will work done be doubled or will it be 0?
