Surface Gravity. part may be reproduced without the written permission. Formula for Acceleration Due to Gravity These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity . Answer: The value of acceleration due to gravity on the moon is 1.625 m/s 2. It is mostly made of flowing icy materials above a solid core. This is the steady gain in speed caused exclusively by the force of gravitational attraction. For reference the time it would take an object to fall 100 meters, the height of a skyscraper, is shown, along with the maximum speed reached. Neglect air resistance in both cases. This .
