# Action and Reaction!

Can anybody prove me that according to newton's third law,every action has equal and opposte reaction. SO why when we push a box it moves ? Why when we squeez a ballon , it becomes small?

Sort by:

see, in the case of the box, we are applying force in the same direction and also the force source is in contact with the box. Also, when we squeeze a ball, we are applying force in both the directions. so, it shrinks. But, in action-reaction pair, such as a gun, the bullet moves away immediately from the gun and it will have a recoil force. In a rocket also, we are pushing gases in the opposite direction. We are not pushing that in the same direction. Also read my new discussion, action-reaction forces as a cause of inertia · 3 years, 11 months ago

Each of these follow Newtons Law, maybe reading how it works better, would give you the answer you wanted. · 3 years, 11 months ago

because action and reaction acts on different bodies. · 3 years, 11 months ago
