According to conservation of momentum, when two objects collide, the momentum lost by one object equals the momentum gained by the other. Give a common-sense, non-mathematical explanation of the connection between Newton’s 3rd law and momentum conservation. In other words,make an argument that Newton’s 3rd law and momentum conservation, though they seem different on the surface, actually “say” similar things. Again, we’re looking for conceptual, commonsense reasoning, not formal mathematical reasoning.
