is the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force. If two surfaces are not in contact, they can't exert a normal force on each other.
the normal force is the component of a contact force that is perpendicular to the surface that an object contacts. For example, the surface of a floor or table that prevents an object from falling.
