An accelerometer is a purely "local" instrument (which, of course, can't tell the difference between gravity and acceleration).
Actually there is a way, or technically 2 ways at least. (besides the fact that experiments have shown that things don't all drop at the same speed meaning that there is a difference between inertial force and gravity) One way is to measure the difference at the floor and ceiling (typically this thought experiment takes place in an elevator).and measure the difference as gravity is of course going to be stronger at the bottom, where a constant acceleration will be equal at each end. The other way is to measures the curvature of the gravity field (measure it's convergence/divergence). But the more important hole is that in real world experiments it is found that things can drop at very different speeds, for instance an iron sphere and a carbon sphere both of the same weight, the carbon sphere will fall faster despite being much larger hence having greater drag. In another case Don A. Kelly, a Free Energy researcher made a device which consisted of a bread board with a bunch of magnets layed out somehow, this would drop something like 1/3rd slower that it should.

But enough bickering. Talking about "centrifugal force", you do know that by running around a bucket of water you incurve the water as if it was centrifuged don't you? :)
Ok, I just tried it, I ran really really fast and you are wrong ;) Funny, now I know your a girl I feel bad about stuff I previously said ;) There are far far too few female interested in science, physics especially and alt science most of all.
