Would the velocity of a body which is orbiting another body change due to its radius to the center of gravity? If so, why? A body which moves passed a planet and starts orbiting it should have the same velocity it had before ,regarding the fact that it is orbiting a planet. Also, gravity isn’t really a force but the geometrical deformation of the fabric of space time. So really is like if you were riding your car in a tilted road so the car curves itself without the need of any forces acting upon it. The more the gravity the more the road is titled.
