Law of Conservation of Momentum

The Law of Conservation of Momentum states that in a closed system where no external forces act, the total momentum remains constant. Momentum is the product of an object's mass and its velocity. When objects collide or interact, they may change speeds or directions, but the combined momentum before and after the interaction stays the same. Think of it like a perfectly coordinated dance: the total "oomph" moving into the dance stays the same, but it can shift from one dancer to another during the interaction without losing any overall motion.
