Question

please explain the law of conservation of momentum with derivation ... please don't sparm ​

Answer 1

Answer:

The law of conservation of momentum says 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.
