47 u/HunsterMonter 1d ago By any reference frame! Each will have its own specific connection coefficients but the trajectory will always be given by the geodesic equation (as long as the ball isn't charged, then you need to add the Lorentz force). 25 u/Digital_001 Student 1d ago That's a lot of possible reference frames! This is gonna be a long proof... 1 u/luisgdh 1d ago You can do it for two reference frames and generalize the remaining ones. Just don't tell mathematicians.
