Principle of Conservation of Momentum. The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision. That is, momentum is not destroyed in the collision, but transferred between the two objects. In an isolated system, momentum is always conserved in a collision. In the example of you catching a baseball, the momentum from the ball is transferred into your hand.
