Question

Why is the normal force always perpendicular to the surface it acts upon?

Answer 1

Explanation:

This is because the normal force, usually represented with Fn or just N, is a force that is directed perpendicular to the two surfaces in contact. It makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.
