MOMENTUM PRINCIPLESForce and MotionCP-03Page 10Rev. 0SummaryThe concepts of momentum and the conservation of momentum are summarized below.Momentum SummaryMomentum is the measure of the motion of a moving body. It isthe result of the product of the body's mass and the velocity atwhich it is moving. Therefore, momentum can be defined as:P = mv.The conservation of momentum states that if no net externalforce acts upon a system, the momentum of the system remainsconstant. If force (F) is equal to zero, then P = 0.The momentum before and after a collision can be calculatedusing the following equation.(m v )+ (m v )= (m v )+ (m v )1 1 initial 2 2 initial 1 1 final 2 2 final
