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.
