The acceleration due to gravity at any point primarily depends on the mass of the celestial body and the distance of that point from the center of that body. The acceleration due to gravity (g) changes on the Earth, the Moon, and Mars. When the dimensions of a body are not trivial compared to the distances of interest, the principle of superposition can be used for differential masses for an assumed density distribution throughout the body in order to get a more detailed model of the "near-field" gravitational acceleration. It is mostly made of flowing icy materials above a solid core. (b) On the surface of Mars? Our experts can answer your tough homework and study questions.

If you could stand on the surface of Uranus (you can't, for so many reasons), you would experience 89% the force of gravity that you experience on Earth. The negative sign indicates that the force is attractive (points backward, toward the source). Your feedback is important to us. (b) Calculate the acceleration due to gravity at Neptune due to Uranus, presently about apart, and compare it with that due to Pluto. Comparative gravities of the Earth, Sun, Moon, and planets, This value excludes the adjustment for centrifugal force due to Earth's rotation and is therefore greater than the 9.80665m/s, Learn how and when to remove this template message, Gravitational potential General relativity, "New ultrahigh-resolution picture of Earth's gravity field", https://en.wikipedia.org/w/index.php?title=Gravitational_acceleration&oldid=1140599103, Short description is different from Wikidata, All Wikipedia articles written in American English, Articles needing additional references from December 2010, All articles needing additional references, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 20 February 2023, at 21:07.
