Depending on the answer to this question, I may have others.
Consider a one-dimensional ice rink. Rightwards is taken as the +x direction. A box of mass m slides leftward on the surface with a constant velocity v.
Two people go to opposite ends of the box and apply equal and opposing forces, and so, v remains constant.
Clearly, the net force on the box is zero and there is no net work done on it. However, the box is still being displaced and there are forces applied. Is work still being done on the box by the people individually in opposite directions?
