Momentum and Impulse Outline Momentum For Newton, this property of an object is its ?quantity of motion? Momentum is a measure of an object?s inertia of motion An objects mass affects momentum An objects velocity affects momentum It is surprising then that momentum is defined as the product of mass and velocity. Momentum = mass * velocity Remember, momentum is conserved The total momentum of an isolated system is constant. Note that "isolated" means that no external force acts on the system, which is a set of interacting objects. If a system does have a net force acting, then the momentum changes according to the impulse equation. Momentum conservation applies to a single object. There are three different kinds of collisions, however, elastic, inelastic, and completely inelastic.
