Phys. Rev. 169, 1017–1025 (1968)Equivalence Principle for Massive Bodies. II. TheoryReceived 16 October 1967; revised 18 January 1968; published in the issue dated May 1968 The acceleration of a massive body in an external field for general space-time geometrical gravitational theories is obtained. The condition on the metric is such that mg/mi=1 is obtained, and we reobtain the result that mg/mi=1 in Einstein's theory for massive objects with time-independent internal structure. But it is shown that a measurement of mg/mi for astronomical bodies would measure space-time metric components which have not been measured in other gravitational experiments. In the scalar-tensor gravitational theory due to Brans and Dicke, it is shown that mg/mi differs from 1 by a term of the order of the massive body's gravitational self-energy divided by its total energy. © 1968 The American Physical Society URL:
