Momentum conservation is a mathematical result of spatial homogeneity (displacement symmetry) (the position in space is the relationship between normative conjugate and momentum). In other words, momentum conservation is the result of the fact that the law of physics does not depend on position, which is a special case of Noether's theorem. In Newtonian mechanics, conservation of momentum can be derived from the law of motion and reaction. This shows that each force has equal opposite force. In some cases, moving charged particles can exert a force on each other in opposite directions. However, the composite momentum of particles and electromagnetic fields is preserved.

Momentum conservation is a law hidden by Newton's law. In other words, the momentum conservation law can infer (prove) the undeniable result of three Newtonian motion rules. It turns out that momentum conservation is more fundamental than Newton's own motion law. I will discuss the power with this proof, but you do not have to deal with the power when using the law of conservation of momentum. The momentum conservation theorem is more fundamental than the third law on which it is based. From the perspective of the 20th century, conservation of momentum is directly related to the identity of the space from one point to another. Even if it is difficult to treat power as a strict Newton, it may be a legitimate statement. History usually determines the order of the original life's proposition, but that is not the order of their ultimate importance.
