Question on calculating gravitation per General Relativity and the field equations: I understand that Einstein's field equations describe spacetime. But I’m not sure of how they are used when evaluating gravitation. For example, the equations describe how spacetime is “curved” by a large object of mass. But how does it say how a smaller object will be influenced by that curvature. If it could be broken down for me: The equations are hard to make sense of. Say, if Earth (A) is the gravitational body with such and such mass, and the acceleration of a ball (B) with such and such a mass, in the air some (X) meters above the Earth’s surface, is effected by the curvature of spacetime (C?). Could you identify these characters in the field equations for calculating the force of gravity on a body?
