Apart from any fair dealing for the purpose of private study or research, no The magnitude of this force is what we know as the weight of the object. What would it be like to walk on other planets? 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. There is no gravitational acceleration, in that the proper acceleration and hence four-acceleration of objects in free fall are zero. In Einstein's theory of general relativity, gravitation is an attribute of curved spacetime instead of being due to a force propagated between bodies. It has enough volume to hold 63 Earths, but it only has 14 times our mass. As a result, Jupiter's surface gravity (which is defined as the force of gravity at its cloud tops), is 24.79 m/s, or 2.528 g. Like Jupiter, Saturn is a huge gas giant that is significantly larger and more massive than Earth, but far less dense. .
