In physics, momentum is the product of an object's mass and velocity, and is represented by the vector quantity p = mv. The equation for momentum is momentum = mass (m) x velocity (v). The unit of measurement for momentum is kilograms meter per second, or newton-second.  Momentum is directly proportional to an object's mass and velocity. For example, a truck with a lot of cargo has a lot of momentum and is difficult to stop at a stop light. A moving bullet also has a lot of momentum because it has a high velocity but a small mass.  Momentum can also be defined as force (F) = change in... Show more
