Normal Forces
Definition
Normal forces are contact forces exerted by a surface to support an object resting on it. They act perpendicular to the surface and counterbalance external forces.
Analogy
Imagine you're standing on a trampoline, and as you bounce up, you feel a push back from the trampoline that keeps you from falling through it. That push back is similar to how normal forces work - they keep objects from sinking into or passing through surfaces.
