So JefferyWhile you can state F = ma this is not the same as saying F = mg. No force is felt in the second equation. So F ≠ mg.
If what you state is correct, how do my bathroom scales work ?
Your bathroom scales work by preventing gravity from moving an object. The tension in a spring will do it. The tension propagates through the spring until it overcomes gravity. Gravity does not propagate through objects, otherwise you would be able to measure your acceleration during free fall.
Look at the slinky drop video in slow motion and see the tension acting against gravity. It is not gravity propagating through the slinky but the release of tension.
This is why the two Fs in the equation about are not the same. Also why I believe you will never be able to properly measure a difference between mi and mg.
