One thing that FE'ers never consider is that while we do measure an upward force, that does not mean that the Earth is accelerating upward. What is being measured isn't the pull of gravity, its the acceleration due to the normal force of the ground.
For example, if you lean against a wall you feel a force pushing you back (otherwise you'd fall through the wall
). The existence of a force, and an acceleration, doesn't mean that the wall is moving, it is simply a results of Newtonian physics.
