The displacement of a body depends on the reference frame of the observer who measures it. It follows that the work done on a body should also depend on the observers reference frame. Suppose you drag a crate across a rough floor by pulling on it with a rope. Identify reference frames in which the work done on the crate by the rope would be (a) positive, (b) zero, and (c) negative.https://bit.ly/YTAI_PWAP https://www.pw.live
