What is freely falling body?
It falls because that’s its natural geodesic path, the “straight line” through spacetime–it is before it falls that some force must be acting on it to keep it from following the geodesic (specifically, the electromagnetic force between the atoms in your hand and the atoms in the object which allows you to keep it in your grip). Imagine I’m standing on a platform accelerating upwards in empty space at 1G. If I hold an object, the platform is accelerating my feet, which accelerates my body, which accelerates my hand, which accelerates the object I’m holding, so we all accelerate together. If I let go of the object, then now there is no force acting to accelerate it, so it will just move inertially in a straight line at constant velocity, the same velocity it had at the instant I let go–and since the platform is continuing to accelerate upward, the platform’s velocity in this direction will increase and so it will eventually catch up with the object, which from my perspective on the pla
