Motion induced Doppler Gravitational Red-Shift The Generalized Gravitational Potential for a Relative Motion Transverse motion has an effect on the measured gravitational red-shift and on the effective gravitational potential for such motion. Transverse Motion The Generalized Potential
Does the Principle of Equivalence imply that a free-fall observer should see the same gravitational red-shift at a particular point in space as a stationary observer? GPS

d R For distances on the order of Earth-Mars, Dd is approximately 19 km, resulting in a time delay of about 250ms, which is what Shapiro observed. Time Delay of Solar Grazing Photon r
Using only Newtonian Mechanics and the Principle of Equivalence, a Dynamic Gravitational Potential was developed to account for relative motion between bodies. • This modified Newtonian potential has been demonstrated to fully account for three “tests” of general relativity: • Mercury’s perihelion shift of 43” per century, • The deflection of a solar grazing photon • The time delay of a solar grazing photon Conclusion
