hi dear
here is your answer
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
...............hope it will help you ...................

law of conservation of momentumsays that momentum only moves from one place to another, since it's neither created nor destroyed.
So let's say that the truck barreling down the highway crashes into a small car, causing it to slow down. It just lost momentum. But momentum can't be destroyed, so where does the momentum go? It goes into the small car, which will now be moving at a different speed (probably faster) than it was before. The momentum transferred from the truck to the smaller car. Momentum was conserved.
But we do have to be careful. Momentum is a vector, which means it has both size and direction. The direction the object is moving matters. Only the total momentum of the whole system has to be conserved. If you have one car moving right with 4 kilogram meters per second of momentum and one car moving left with 4 kilogram meters per second, the total momentum of the system is zero; the two cancel out. So if the two cars crash together and stop, momentum has been conserved just fine because there wasn't any overall momentum at the start
Total momentum before collision = Total momentum after collision.
