Question

Quizplus · Accepted Answer

The force of gravity pulling you down and the normal force (support force) from the floor pushing you up are not an action-reaction pair according to Newton's third law. The action-reaction pair for your weight would be the Earth pulling you down and you pulling the Earth up. The normal force is a separate reaction to your body pressing down on the floor.
