Question

explain law of conservation of momentum

Answer 1

to explain law of conservation of momentum let us consider two bodies a and b so now consider a situation in which A and B together and as we know from Newton's third law of motion a body if colliding with every other than here in this situation a body is collided with B letters A body moving from direction west to east and vice versa for body me now the force applied by body a on b is equal to the opposite force applied by body be on a now as we know force of a on B = negative force of beyond that we can say - f on BA so now force of A and B = any change in momentum of I mean the force of a on B equals change in momentum of B divided by time that equals equal to any change in momentum of a / time so now time cancel each other from both sides now we get linen change in momentum of a = Lena change in momentum of me and clean change in momentum equals MB MB = MB minus values of a and on the other side right hand side we get m m b minus value of B now MV - MV of beings and you of B = negative bracket start MV of bebe Army of MV of a minus m u of a that is equal to know the we take the initial Momentum in one side and final Momentum in one side so we get Value of A + m u of B = MB of a + MV of wheels that is equal to total initial Momentum is equal total final moment so hence we prove the law of conservation beside explaining it

Answer 2

that is the momentum can be conserbed by the following experiment :
during a collision between two body the total momentum of the two body is same as after the collision so the momentum get conserbed.
thus it's as follows if a body 1 has a large amount of momentum and another have less. so after the collision the larger body with large momentum push or strike the lesser momentum body backward. so here the momentum of the larger body does not he destroyed the momentum of the two body get conserbed. and both of the momentum are same as before the collision.
