Where can I find examples for solving equations of motion in Relativity?

Hi,

I am a new GR student and struggling a bit, to be honest. Usually in this situation I saturate myself with working through examples and eventually the penny drops, but I have not been able to find a text or any lecture notes etc. that provides examples of things like solving geodesic equations of motion given a metric ( they don't all seem responsive to the Lagrangian approach) or rewriting metrics or equations of motion in a different coordinate system etc.etc.
Can anyone help by suggesting a text?

Thanks

Thanks robphy. I'll have a look at those.
 

Thread 'I don't see how a black hole's event horizon can be crossed'

OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...

Thread 'Question about Parallel Transport'

In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...

Thread 'Trying to calculate proper time of worldlines using rotating frames'

So, to calculate a proper time of a worldline in SR using an inertial frame is quite easy. But I struggled a bit using a "rotating frame metric" and now I'm not sure whether I'll do it right. Couls someone point me in the right direction? "What have you tried?" Well, trying to help truly absolute layppl with some variation of a "Circular Twin Paradox" not using an inertial frame of reference for whatevere reason. I thought it would be a bit of a challenge so I made a derivation or...
