Explanation:
Collisions and Momentum
If you're a sports fan, you've seen plenty of collisions. These collisions occur between players but also between a baseball and a bat, a tennis ball and a racket, and a football and the kicker's foot. All of these are collisions because two or more objects came in contact with each other.
During a collision, the objects that come in contact with each other are considered a system. And as we learned in another lesson, this system follows the law of conservation of momentum, which states that the momentum of a system does not change when there are no external forces acting on it.
The momentum of the overall system doesn't change, but that doesn't mean that the momenta of the individual components of the system don't. Quite the opposite is true - the different parts that make up the system do have a change in momentum, but they are equal in magnitude and opposite in direction, so they cancel each other out.
