... In this first case the two teams would be in equilibrium, i.e. nobody’s moving. If team 1 increases their force, then team 2 would also increase its force. But deciding who moves is not about third law pairs, it’s about Newton’s Second Law. We only look at the forces on one object: Fnet = F2on1 - f ...
