r is not a constant. As a position vector its scalar product with absolute acceleration is a constant square of light speed. So if
r approaches infinity then the absolute acceleration approaches zero. From Galileo's experiments it was proven that the local acceleration of gravity small
g does not depend on the inertial mass
m. It depends on the big mass
M. more later.
