It is a vector oriented toward the field source, of magnitude measured in acceleration units. And when it comes to the planets of our solar system, which vary in size and mass, the strength of gravity on their surfaces varies considerably. The surface gravity may be thought of as the acceleration due to gravity experienced by a hypothetical test particle which is very close to the object's surface and which, in order not to disturb the system, has negligible mass. Uranus' gravitational pull would be about 91% of The surface gravity on Uranus is about 86% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 86 pounds on Uranus (assuming you could find someplace to, well, stand). or, by Matt Williams, Universe Today.

Acceleration due to gravity means the force due to weight of an Based on their sizes and masses, the gravity on another planet is often expressed in terms of g units as well as in terms of the rate of free-fall acceleration. {/eq} kg. Because of this, Mars has 0.38 times the gravity of Earth, which works out to 3.711 m/s2. Planets like Uranus or Neptune, which much less hydrogen and helium - probably not as much, but for gas giants and most stars, gravity very likely increases . This calculates the weight on mars from the weight of the object on earth. The general rule is that acceleration decreases with height: higher objects have less acceleration.
