Momentum Not Conservation Principle

Abstract: Momentum is not conserved, the momentum conservation law is wrong. Socalled internal force is equal and orientation reverse geminate appear, the plight of naught of external force, total internal force vector sum of a system is zero, so the total momentum of the system does not change. this inference of the momentum conservation law, in fact, is only applicable in the particle one another collide, or collide plight with object centroid one another. when several objects at the same time interaction, of Its bring counterforce,sometimes do not do work to the object, at this time the vector sum of the system internal force, it not equal to zero may. so system momentum is conserved is anymore, namely momentum is not conserved.
