The above acceleration is due to the gravitational pull of earth so we call it acceleration due to gravity, it does not depend upon the test mass. Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.
Formula: g = GM/r2
Values of g in CGS: 980 cm s-2
Dimensional Formula: M0L1T-2
Values of g in SI: 9.806 ms-2
