A "normal" force is a force, or component of a force, that is perpendicular to the surface upon which it acts.
"Normal" does not mean "usual" or "average" in this case. It means perpendicular.
is force and normal force the same thing? if not what is the difference. for instancee if a problem said given a force of 20 newtons. would normal force be 20 newtons?
please answer !!!!!!!!!
