Remember as was pointed out the accelerometer measures its acceleration.
In a gravitational field it will measure the fields acceleration, but when
you drop it, it is in free fall and its acceleration relative to its
falling self is zero just like an astronaut on the space station. As
pointed out accelerometers measure their acceleration not the face acting
on them. They are a tricky device because they are not measuring force but
acceleration. How would you take a force probe and an accelerometer and
determine the mass of the object being pulled?
