1) What is the expected value for total work in each part of the experiment? 2) Why is the total work done so different between parts 1 and 2? 3) Is work necessarily a positive quantity? 4) If you drag a heavy box across a rough floor; is the work done on the box, in dragging it from point A to point B, independent of the path taken? Explain your answer. 5) The force on an object is non-zero. Over some path, the work, done on the object is zero. Is it possible that the object has moved in a straight line? Explain you answer.
