Velocity, acceleration and gravity in Einstein's relativity

Abstract
Einstein's relativity theory demands that all meaningful physical objects should be defined covariantly, i.e. in a coordinate independent way. Concepts of relative velocity, acceleration, gravity acceleration and gravity potential are fundamental in Newton's theory and they are imprinted in everyone's physical intuition. Unfortunately, relativistic definitions of them are not commonly known or appreciated. Every now and then some confused authors use wrong, non-covariant, definitions of velocity, acceleration and gravity, based on their vague Newtonian intuitions and hidden in a superficial, often purely semantic, relativistic disguise. A recent example of such a confusion (Gorkavyi & Vasilkov, 2016) is discussed at the end of this Note.
Even if you wrote in your later replies here that (your words follow) "the math in the original article is more or less solid, no errors were found since publication in 2016" that statement seems quite dishonest, as you also wrote later, as you communicated with me, that you are…
