In the absence of external forces, the total momentum of the system is conserved so using this law we can write the following equation about the two colliding. Momentum the momentum of a particle is defined as the product of its mass times its velocity it is a vector quantity the momentum of a system is the vector. A 288 g yellow air hockey disc elastically strikes a 269 g stationary red air hockey disc if the velocity of the yellow disc before the collision is 336 cm/s in the x. A better definition of newton's 2nd law is to say that the force is directly proportional to the rate of change of momentum and acts in the same direction ( this last.
