So in Layman's terms, there really isn't an acceleration due to gravity. The acceleration observed of the falling object by a person on the ground is due to mechanical forces from the ground and in truth, the gravity never actually caused any acceleration of the falling object. Correct? To the...
If the effects of gravity are relative to an objects stress-energy-momentum tensor, is the equation:
Fg = Gm1m2/r^2
fundamentally flawed since it is based off the mass of the two objects? Ignoring the "gravity isn't a force" (I understand that it is what is observed due to curves in spacetime)...
If this question has an obvious answer, please excuse my ignorance. I'm still very new to the world of physics relative to most of you. But my question is simple. In Newtonian physics I know the rather simple explanation along with the corresponding formulas but in modern physics I'm a little...
