$$ There's NO inertial (iNTRiNSiC REST) mass is Newton's equation.
$$ M*v = m*v_g.
$$ "Gravitational" mass is M, where m is Newton's GiVEN test-mass.

$$ NOTE edited BOTTOM section (added new EQUATiON & [BOTTOM line]):
$$
$$ GEDANKEN acceleration EXPERiMENTAL data ANALYSiS:
$$ Apparatus..
$$ F_constant G*M v^2
$$ Acceleration, if a = -- - -- -- = g_constant = -- -- -- -- = ---
$$ m (n - 1)*r^2 r .
$$ Conclusion..
$$ With a LOCAL CONSTANT FORCE, F, (where m*a = m*g), g is CONSTANT.
$$ [This means, if the acceleration a varies, TEST mass, m, varies.]
$$ This is PROOF LATERAL acceleration a VARiEs, where g is CONSTANT.
$$ [This means, if given TEST mass m varies, mass M ..OR n, varies.]
$$ This is PROOF GRAViTATiONAL acceleration g iNDEPENDENT of mass m.
$$ [This means, if given TEST mass m varies, velocity v OR r, vary.]

What are the two kinds of Masses ?? [SORRY previous post VAGUE].
m*a=m*g_constant & F_constant @ r. End of CORRECTED RePOST.

IIRC from high school science classes there are 4 kinds of matter.
