If there are two things attracted to each other, does the accelaration of gravity depend on both masses

mass[other] = mass of other body,D = distance center-to-center,Note: for very dense objects (neutron stars, stellar-mass black holes) or very high speeds (3% of light speed or more), General Relativity is needed for an accurate analysis.For very small distances (atomic scale),......
or only one mass? If so, which mass

-
The force depends on the product of the masses. How each mass accelerates because of that force depends on the other mass.

acceleration = G mass[other] / D^2
G = 6.67384 x 10-11 m^3 kg^-1 s^-2
mass[other] = mass of other body, in kilograms
D = distance center-to-center, in meters

Note: for very dense objects (neutron stars, stellar-mass black holes) or very high speeds (3% of light speed or more), General Relativity is needed for an accurate analysis. For very small distances (atomic scale), you need quantum mechanics. The details are too complicated to give here.
