Abstract

In a series of papers, Abramowicz and coworkers have shown that the interpretation of relativistic motion in terms of «Newtonian forces» can provide intuition about the space-time geometry, in spite of an inherent ambiguity of 3-dimensional language within relativity. Considering a general space-time, I suggest here a decomposition of test particle's 4-acceleration into contributions from the «gravitational» («gravitoelectric»), the «dragging» («gravitomagnetic»), the «Coriolis», the «centrifugal» («normal-intrinsic-inertial-resistance») and the «tangent-intrinsic-inertial-resistance» forces. I show that the decomposition yields, at least in several «standard» situations, very plausible results. Connections of the presented point of view with «gravitoelectromagnetism» are outlined in the appendix.
