The value of the attraction of gravity or of the potential is determined by the distribution of matter within Earth or some other celestial body. In turn, as seen above, the distribution of matter determines the shape of the surface on which the potential is constant. Measurements of gravity and the potential are thus essential both to geodesy, whi...

As a result of combining all available absolute and relative measurements, it is now possible to obtain the most probable gravity values at a large number of sites to high accuracy. The culmination of gravimetric work begun in the 1960s has been a worldwide gravity reference system having an accuracy of at least one part in 107 (0.1 milligal or better).
The value of gravity measured at the terrestrial surface is the result of a combination of factors:
1.The gravitational attraction of Earth as a whole
2.Centrifugal force caused by Earth’s rotation
3.Elevation
4.Unbalanced attractions caused by surface topography
Although the Apollo astronauts used a gravimeter at their lunar landing site, most scientific knowledge about the gravitational attractions of the Moon and the planets has been derived from observations of their effects upon the accelerations of spacecraft in orbit around or passing close to them. Radio tracking makes it possible to determine the accelerations of spacecraft very accurately, and the results can be expressed either as terms in a series of spherical harmonics or as the variation of gravity over the surface. As in the case of Earth, spherical harmonics are more effective for studying gross structure, while the variation of gravity is more useful for local features. Spacecraft must descend close to the surface or remain in orbit for extended periods in order to detect local gravity variations; such data had been obtained for the Moon, Venus, Mars, and Jupiter by the end of the 20th century.
The Moon’s polar flattening is much less than that of Earth, while its equator is far more elliptical. There are also large, more-local irregularities from visible and concealed structures. Mars also exhibits some large local variations, while the equatorial bulges of Mercury and Venus are very slight.
The acceleration due to gravity on the Moon is about 1.62 m/s^2, while on Earth, it’s around 9.81 m/s^2. This means that on the Moon, you can jump higher, throw farther, and carry heavier objects than on Earth.
Explain Earth’s gravitational force. Describe the gravitational effect of the Moon on Earth. Discuss weightlessness in space. Examine the Cavendish experiment. What do aching feet, a falling apple, and the orbit of the Moon have in common? Each is caused by the gravitational force.
