... A boy pushes his wagon at constant speed along a level sidewalk. The graph represents the relationship between the horizontal force exerted by the boy and the distance the wagon moves. As the boy pushes the wagon, what happens to the wagon’s energy? (A) Gravitational potential energy increases. (B) ...

... be a transfer of some “motional stuff” from your foot to the ball. When you knock bowling pins down with a bowling ball, a similar thing seems to be happening. Can we quantify this “motional stuff” as a conserved quantity? For many years, physicists investigated different combinations of mass and sp ...
