Z 보존 refers to a concept in physics related to the conservation of certain quantities in a system. Specifically, it often pertains to the conservation of angular momentum in quantum mechanics, where the Z component of angular momentum remains constant in isolated systems. This principle is crucial for understanding the behavior of particles and their interactions. In practical terms, Z 보존 helps scientists predict how particles will behave in various situations, such as in particle collisions or in the presence of external forces. This conservation law is fundamental in fields like quantum physics and particle physics, guiding researchers in their experiments and theories.
