# Equation for velocity of a object in a dynamic gravitational feild [closed]

Two objects A and B in other space of masses $$M1$$ and $$M2$$ are separated by a distance $$r$$. The $$Δg$$ with $$Δh$$ is not negligible. Integrate a function $$f(t)$$ with time as an input for velocities $$v1$$ and $$v2$$ of objects A and B respectively taking into account $$g$$ at a point changes due to either of the objects because both objects accelerate towards each other?

• Why did you assign the “general-relativity” tag? – G. Smith Nov 22 at 4:37
• @G.Smith - their teacher is cruel. – Myridium Nov 22 at 4:43

• As far as I know, there is no analytic solution for this in GR. – G. Smith Nov 22 at 6:05
• @Ace also mention your work. Where are you facing problem. Then we will have a decent discussion – Anonymous Nov 22 at 7:49
