... The Principle of Conservation of Momentum When two particles A and B collide, they exert equal and opposite forces, and hence impulses, on each other. The impulse that A exerts on B (equal to B’s change in momentum) is therefore equal and opposite to the impulse that B exerts on A (equal to A’s chan ...
