Abstract

In Teleparallel Gravity it is possible to obtain separate expressions for the energy-momentum density of gravity and of the interaction of gravity with inertial effects of the frame. The energy-momentum density of gravity shows up as a true tensor, and satisfies a covariant conservation law. The energy-momentum density associated to the inertial effects is neither conserved nor covariant. Together, they form a pseudotensor conserved in the ordinary sense. This means that the non-covariance of the usual expressions for the gravitational energy-momentum density is not an intrinsic property of gravity, but a consequence of the fact that they include also the energy-momentum density related to the inertial effects.
