Newton's third law confusion!?! If A exerts some force on B then it experiences a force of same magnitude and in opposite direction. This didn't seem intuitive to me so I thought of it this way, Let A and B be a single system. Now there is no net external force acting on the system so the momentum must be conserved and thus the forces exerted should be equal. Is this the correct way of thinking this or not? Is there a more intuitive way of perceiving this law? Thanks in advance.
