Momentum and Impulse

Momentum and Impulse. Momentum. Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum Momentum depends upon the variables mass and velocity Momentum = (mass) (velocity) p = (m)(v) where m = mass and v=velocity. Momentum.
