Nonetheless, Newton's laws still apply--that's where the so-called "work"-energy theorem comes from. In order for the man to accelerate, there must be an external force on him, which is friction. But that friction does no real work, thus does not … WebNormal Force. The normal force is the force that keeps us from falling to the center of the earth. Every surface or object we stand on exerts a force back on us. Otherwise, we would fall through the object/surface due to the force of gravity. The normal force is a reaction force, and as such has no formula specific to it.
