Expressions have a numerical value. This law becomes a powerful tool in physics because it allows for predictions of the before- and after-collision velocities or mass of an object. The sum of two numbers is 84, and one of them is 12 more than the other. The three problems above illustrate how the law of momentum conservation can be used to solve problems in which the after-collision velocity of an object is predicted based on mass-velocity information.
