How the law of conservation of momentum related to newtons third law of motion?
All mechanics is related in some way. Newton’s laws are ways of describing forces but there are other ways. N3 forces equal but opposite, in a collision the force exerted by one object on another is equal to the force exerted by 2nd on first and over the same period of time F=ma = m* (change of velocity) / t Force of 1 on 2 = m2 *(change of velocity of 2) / t =Force of 2 on 1 = m1 *(change of velocity of 1) / t The t cancels and you are left with the change of momentum of each being equal.
