Acceleration due to Gravity Formula What is Acceleration due to Gravity? Follow Published on Aug 10, 2010. But, at large distances from the Earth, or around other planets or moons, it is varying. Review Equation 1, which indicates that this graph should be linear with slope equal to g. Click here for Solved Example G.6: Acceleration due to Gravity at a Depth. Answer: On the surface of the moon, the distance to the center of mass is the same as the radius: r = 1.74 x 10 6 m = 1 740 000 m. The acceleration due to gravity on the surface of the moon can be found using the formula: g = 1.620 m/s 2
