Phys Sci Chapter 3 notes
... Law of conservation of momentum—states that total momentum is neither created or destroyed, but it is transferred in collisions. Example: when you hit a cue ball for the first time in a game of pool, it has all of the momentum. When it strikes the other pool balls, it transfers some of its momentum ...
