Which of these situations has a normal force? Warm-up Which of these situations has a normal force? What is the normal force equal too?

A free body diagram is pictorial representation of all the forces acting on an object. We will be using all those notations to denote which force is acting on the object. Each one could have multiple forces acting on it.
