normalkraft
Normalkraft, in physics commonly called the normal force, is the contact force exerted by a surface on a body that presses against it. It acts perpendicular to the surface, along the surface normal, and arises from the microscopic interaction between the surface and the object. The normal force prevents interpenetration of the two bodies and adjusts in magnitude as other forces change.
In the simplest case, a block rests on a horizontal table with gravity acting downward. If there
The normal force can differ from the object's weight when other vertical forces are present or when
Normalkraft is a constraint force and is closely related to friction, which depends on N. The frictional
