When a skydiver falls from the sky, the person feels as though he or she is completely weightless, and when on the ground, the person does not.
We can assume weight to be equal to the force of acceleration of the ground according to the equation F=ma. Yet we don't typically say that the ground is accelerating us upwards, we say the force of gravity is pulling things downward. What's wrong with the notion that the thing we experience as gravity is the result of the ground accelerating the person upwards?
