In classical mechanics, the dynamics of a particle ( or system of particles ) are completely determined by the Lagrangian L ( q, q ̇, t ) or equivalently the Hamiltonian H ( q, p, t ), a function of the generalized coordinates q, generalized velocities q ̇ = dq / dt and its conjugate momenta:
If either L or H are independent of a generalized coordinate q, meaning the L and H so not change when q is changed, which in turn means the dynamics of the particle are still the same even when q changes, the corresponding momenta conjugate to those coordinates will be conserved ( this is part of Noether's theorem, and the invariance of motion with respect to the coordinate q is a symmetry ).
This is related to Lorentz invariance, since an infinitely massive particle is always nonrelativistic, and the spin decouples from the dynamics.
