Explain how momentum gets conserved in collision of two bodies?

Momentum is known as the result of the product of the mass of an object and its velocity. 

According to the law of conservation of momentum: For a collision happening between object 1 and object 2 in a secluded framework, the total momentum of the two items before the collision is equivalent to the absolute momentum of the two items after the collision. 

That is, the momentum lost by object 1 is equivalent to the momentum acquired by object 2. 

Therefore, according to the law of conservation of momentum, the total momentum of the two objects before the collision is equivalent to the total momentum of the two objects after the collision. 

So the total momentum of the two moving objects remains the same before and after the collision.
