The difficulties encountered in developing a theory of gravitation may be traced to the limited body of available experimental data. A special class of coordinates, the nonrotating coordinates, is established by means of a variational pronciple imposed on the spacetime integrals of the components of the energy-momentum tensor. The authors show that the nonrotating coordinates where energy and momentum are globally conserved share the experimetnal features of the special relativity inertial frames (Newton's and Einstein's). The falling of matter in a spherically symmetric gravitational field is analyzed based on the valid energy and momentum conservation in these coordinates. 8 refs.
