Discover LudwigThe phrase "a normal force" is correct and usable in written English.
It is typically used in physics to describe the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.
Example: "When an object is placed on a flat surface, the normal force acts upward to counteract the force of gravity pulling the object downward."
Alternatives: "the support force" or "the perpendicular force".
