OA is the answer
Newton's third law of force states that: for every action (force) in nature there is an equal and opposite reaction. what this means is that if I push on you, you're also pushing me because I have slowed down but now you are falling to the mud.
if you have ever seen newtons balls then you will know what I am talking about, one is moving then it hits the other and it stops moving because now the other one is moving,
I hope this makes sense, if it doesent then go to the net and watch some videos on Newtons third law
hope it helped
