Does General Relativity imply greater accelerations than Newtonian gravity in strong gravitational fields, such as at 2 m/s^2?

Do the general relativistic corrections add up to more "gravity" in strong gravitational fields?

Yes, instead of the Newtonian $\rm F=m \ a=G \ M \ m/r^2$, under Schwarzschild we have $\rm F=m \ a=G \ M \ m/r^2/\sqrt{1-r_s/r} \ $ for a stationary observer, and at $\rm r=1.5 \ r_s \ $ you'd need $\rm v=1 \ c \ $ in order to orbit, while under Newton you'd need only $\rm 0.577 \ c$, see here.

  • $\begingroup$ @m4r35n357 - Sure, it's the circumference divided by 2π as per the usual convention. $\endgroup$

  • $\begingroup$ It is an identification, but it is clearly not the same thing. Anyway, I have done this myself in order to "compare" orbits in Newton with GR, so I am pragmatic about it, I just don't take it seriously as the "same thing". $\endgroup$
