Two different values for the speed of light have been derived in prior issues of Galilean Electrodynamics, using the conservation of energy. It is shown that the conservation of energy simply defines a relationship between the gravitational dependence of the speed of light and the gravitational dependence of mass. Thus, when one uses the conservation of energy to determine the gravitational dependence of the speed of light, one must presuppose either explicitly or implicitly the dependence of mass on gravitational potential. The author uses the Shapito radar time delay to define the dependence of the speed of light on gravitational potential. The conservation of energy can then be used to define the dependence of mass on gravitational potential. The implications of the development are explored. From the development, it is clear that conservation of momentum predicts a result for Gravity Probe B which is different from that predicted by the general theory of relativity.
