ocr: What IS momentum: In order to stoP a moving pinball, a force must be applied to it, such as that supplied by a target. A fast- moving, heavy object will require more force to stop it than a slow- moving light object. An object's momentum is what makes it easy or difficult to stop. Momentum depends on the velocity of an object and its mass. If either of these quantities increases, then the momentum increases. To calculate an object's momentum, you multiply its mass byits velocity: Momentum = Mass X Velocity - Ifsomething is stationary, no matter how heavy it is, it will have no momentum. A mous ...
