* The normal force is always perpendicular to the surfaces in contact. This is the origin of its name - normal to the surface. ... * The normal force is an action-reaction force. A surface will not exert a normal force on an object in contact with it unless some other external force pushes the object into the surface.

; What is the Normal Force? This is a force of CONTACT. If there is no contact between the object of interest and some other surface, e.g. a floor, there is NO Normal Force. ... We call the force that the floor exerts on the box a Normal Force as the force acts NORMAL to the surface upon which the box is resting. Note,

The normal force can be provided by any one of the four fundamental forces, but is typically provided by electromagnetism since microscopically, it is the repulsion of electrons that enables interaction between surfaces of matter.

Gravity is a long-range force; other forces only occur when objects come into contact. One example of a contact force is the normal force. ... The normal force is just the component of a contact force which is perpendicular to the plane of contact. It prevents objects from moving through each other.

Don't fall into the trap of assuming that the normal force exerted on an object is always equal to the weight of the object. Imagine that the object is resting on a scale that gives a reading in Newtons, this reading would be the magnitude of the normal force...

Since it is the force perpendicular or "normal" to the surfaces which affects the frictional resistance, this force is typically called the "normal force" and designated by N. The frictional resistance force may then be written:
