1. normal forcePhysics
2. Normal forceIn mechanics, the normal force (occasionally N) is the component, perpendicular to the surface of contact, of the contact force exerted on an object by, for example, the surface of a floor or wall, preventing the object from penetrating the surface. The normal force is one of the components of the ground reaction force and may coincide with it, for example considering a person standing still on the ground, in which case the ground reaction force reduces to the normal force.
