Have you ever seen a game of tug-of war? In this game two teams pull at a rope in opposite directions . Members of both the teams try to pull the rope in their direction. Sometimes the rope
simply does not move. The team that pulls harder, that is, applies a larger force, finally wins the game. What do these examples suggest about the nature of force? Forces applied on an object in the same direction add to one another. Now recall what happened when you and your friend pushed the heavy box in the same direction . 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. What did you observe , when both of you were pushing the heavy box from opposite directions? Recall that in the tug-of-war when two teams pull equally hard, the rope does not move in any direction. So, we learn that a force could be larger or smaller than the other or equal to each other. The strength of a force is usually expressed by its magnitude. We have also to specify the direction in which a force acts. Also, if the direction or the magnitude of the applied force changes, its effect also changes.
Answer the following questions
a) What is the net force if the game given below is drew?
b) The team that pulls harder, that is, applies a larger force, finally wins the game. Justify.
c) What is the strength of the two forces F1 & F2 , if they are applied along the same direction ?
Where F1 is twice the F2.

Answer:
Net force=0
the motion is toward the side with non zero force after cancelling each other
if they are applied in sam side f= F1+F2
if 3f1
