Conservation of impulse and momentum
... For a system of particles, we can define a “fictitious” center of mass of an aggregate particle of mass mtot, where mtot is the sum ( mi) of all the particles. This system of particles then has an aggregate velocity of vG = ( mivi) / mtot. The motion of this fictitious mass is based on motion of t ...
