A force between the two objects only when they interact with each other. 4. The sum of forces acting on bodies is called net force. 5. Forces applied on an object in the same direction add to one another then net force = f1 + f2 6. If the two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces. then net force = f1 +(- f2) 7.
