[QUOTE="Dukon, post: 6067278, member: 568099"] if the Hamiltonian is changed by adding a potential energy V which is velocity-independent then the conjugate momentum will not change. For the gravitational field case, the potential energy V = mgz which has no velocity dependence so the derivative by velocity of any lagrangian with any v-independent V will be the same either with or without this V. This is true for any V which has no velocity dependence not just the gravitational case. Are you worried about cases where V is explicitly a function of v only or will the gravitational case satisfy your actual issue? [/QUOTE]
