OK, I realize this is probably going to sound stupid, but I'm planning to major in English so all this physics stuff escapes me. We're talking about Newton's Third Law in class, and we did an experiment on the elevators where we weighed ourselves the moment we stop and compare it to when we're moving with constant velocity and at rest. We figured out that the reason for the difference is that the normal force from the floor pushes up on us at a different strength at these points. My question is this: Isn't this a violation of that "equal and opposite reaction" law? Or am I just incredibly retarded?
