The Galileo symmetry

The Galileo symmetry is investigated and the condition on the Lagrangian corresponding to this symmetry, and the corresponding constant of motion are obtained. The relation of this symmetry with the translational symmetry is studied and it is shown that if in addition to the Galileo transformation time translation is a symmetry, the position translation is also a symmetry.
