Confidence votes 54.6K. They are totally unrelated. A net force is the sum of all forces that act on an object. A normal force is the part of a force (of an individual force, or on a net force) that acts normal, i.e., perpendicular, to a specified direction.ewton's third law states that every action has an equal and opposite reaction. This implies that the force is acting on two different bodies. Whereas, net force implies the a â¦ rithmetic sum of all the forces acting on a single body. Answer2:'The difference is Newton;s 3rd Law involves zero net force.
