Don,
permitt sir a quote:
"In the Einstein experiment, as you describe it, the observer could not tell if he was moving or at rest. Comparison of the force vectors that attract him to the floor at various points in the elevator would would allow him to make that distinction. If the vectors are all parallel, the force is due to acceleration. If the vectors are concentric, the force is gravity."

concentric?
actually any imaginable force vector that one can come up with is going to point toward the floor of the elevator in either case. that is one very good reason that acceleration and gravity obey the equivalency principle.

cheers tim
