What is the conservation of angular momentum?
The angular momentum of a system of isolated basic particles never changes. This conservation law results since the angular momentum of a particle which is not impacted, of course, is constant. The only change that can ever occur to a basic particle is for two of them to collide. During collision only the normal components of velocity of the particles are changed and they simply interchange between the particles. Thus, a collision does not change the angular momentum and it thus follows that the angular momentum of a system of isolated basic particles never changes. This completes the conservation equations; mass is conserved, energy is conserved, linear momentum (in three directions) is conserved, and angular momentum (in three directions) is conserved. Any process occurring in the universe must obey all these conservation laws.
