Thus, the value of g on the Earth is g=9.8m/s 2. To find the weight on Saturn, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. Gravity is measured by the acceleration that it gives to freely falling objects. Uranus is more . All objects are attracted to the earth, and the direction of that force is towards the centre of the earth. The surface gravity on Uranus is less that that of Earth, due mostly to the relatively low density of . Calculate the force of gravity on a spacecraft 19,200 km (3 earth radii) above the Earth's surface if its mass is 1600 kg.

Gravity is a fundamental force of physics, one which we Earthlings tend to take for granted. Titania, the largest moon of the planet Uranus has 1/8th the radius of the earth and 1/1700th the mass of the earth. The radius of Earth is 6.4 10 6 m. Substituting the values in the formula we get-. There is no gravitational acceleration, in that the proper acceleration and hence four-acceleration of objects in free fall are zero. 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. All rights reserved. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.
