Law of Conservation of Momentum
... pTOTAL (i ) pTOTAL ( f ) Momentum can be transferred from one part of a system to another, but the total amount remains constant. Momentum is conserved during any interaction among objects – collisions, explosions, etc. – since these interactions involve INTERNAL impulses (one part of the system ...
