Kindly help me understand the difference between
F=ma and F=mg.
We have covered this issue many times in other settings:
eg Does E equal mc^2 or is it that E _is_ mc^2 .
In the present case
F=ma means that if I calculate/measure F and calculate m x a they will be
equal.
F=mg means that the force _is_ m x g.
Again, mg is a force, ma is not.
It would seem to me that this issue should have been long since settled. I
must be missing something here.
