For 10 points, name these laws that say that certain quantities remains constant in a system.
The reason that the sigma star plus particle doesn't decay into a proton and a neutrino is due to one of these proposed by Heisenberg. That one only applies in strong interactions and was made to explain the similarities between the neutron and proton. Another one of these is due to the fact that phase shift of a wavefunction can't be observed, while a different one of these must exist due to the invariance of the Lagrangian to position. With any given symmetry, a corresponding one of these exists according to Noether's theorem, yet another one of these applies when there is no external torque. Inelastic collisions require two of these for motion calculation, while elastic collisions require only one. Important ones include ones for angular momentum, linear momentum, energy, and charge.
