Remember, Nasa is now inferring gravity isn't what originally assumed. Magnetics are now playing a larger part in the study of the gravity theory. 2cents and SS may be able to expound on this. |

Jump to: navigation, search Gravitation Portal Earth's gravity, denoted by g, refers to the attractive force that the Earth exerts on objects on or near its surface. Its strength is loosely said in terms of the acceleration produced by it (accelaration due to gravity), which in SI units is measured in m/s² (metres per second per second, equivalently written as m·s−2). It has an approximate value of 9.8 m/s², which means that, ignoring air resistance, the speed of an object falling freely near the Earth's surface increases by about 9.8 metres per second every second. There is a direct relationship between gravitational acceleration and the downwards weight force experienced by objects on Earth. This is explained at weight; see also apparent weight. The precise strength of the Earth's gravity varies depending on location. The nominal "average" value at the Earth's surface, known as standard gravity is, by definition, 9.80665 m/s² (32.1740 ft/s²). This quantity is denoted variously as gn, ge (though this sometimes means the normal equatorial value on Earth, 9.78033 m/s²), g0, gee, or simply g (which is also used for the variable local value). The symbol g should not be confused with G, the gravitational constant, or g, the abbreviation for gram (which is not italicized). The change in gravitational strength per unit distance (in a given direction) is known as the gravitational gradient. In the SI system this is measured in m/s² (strength) per metre (distance), which resolves to simply s−2 (inverse seconds squared). In the cgs system, gravitational gradient is measured in eotvoses.

Quoting: Anonymous Coward 1114211What a great post, I have never thought about it that way, but that's true. |
