Q:

What is the law of conservation of momentum?

A:

The law of conservation of momentum states that you must have the same amount of momentum before any event as you do after. Momentum, (mass x velocity) must always be conserved. For example, when two cars run into each other, their velocities might change, but if you measure the mass and velocity of every piece of that collision, the combined momentum of those pieces will exactly equal the momentum of the two cars before the collision.
