Is it possible to find the speed increase due to gravity pull using the SR velocity addition formula or the calculator here?
http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/einvel2.html
Can you confirm that it is in accordance with GR formula?
For example, if an asteroid is approaching the Earth at √3 /2 c, considering g constant (10 m/s^2)for a whole second the hyperphysics calculator says the increase is 2.5 m/s (instead of 10)
Is it an acceptable approximation?
