Although the actual acceleration of free fall on Earth varies according to location, the above standard figure is always used for metrological purposes. In particular, since it is the ratio of the kilogram-force and the kilogram , its numeric value when expressed in coherent SI units is the ratio of the kilogram-force and the newton , two units ...
The precise strength of Earth's gravity varies with location. The agreed-upon value for standard gravity is 9.80665 m/s 2 (32.1740 ft/s 2 ) by definition. [ 4 ] This quantity is denoted variously as g n , g e (though this sometimes means the normal gravity at the equator, 9.7803267715 m/s 2 (32.087686258 ft/s 2 )), [ 5 ] g 0 , or simply g ...
In physics, gravity (from Latin gravitas ' weight ' [1]) is a fundamental interaction primarily observed as a mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force, and 10 29 times weaker than the weak interaction.
The English proper name for Earth's natural satellite is typically written as Moon, with a capital M. [19] [20] The noun moon is derived from Old English mōna, which stems from Proto-Germanic *mēnōn, [21] which in turn comes from Proto-Indo-European *mēnsis 'month' [22] (from earlier *mēnōt, genitive *mēneses) which may be related to the verb 'measure' (of time).
It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With over 39 million residents across an area of 163,696 square miles (423,970 km 2 ), it is the most populous U.S. state , the third-largest by area , and the most populated subnational ...
Austin, Travis County and Williamson County have been the site of human habitation since at least 9200 BC. The area's earliest known inhabitants lived during the late Pleistocene (Ice Age) and are linked to the Clovis culture around 9200 BC (over 11,200 years ago), based on evidence found throughout the area and documented at the much-studied Gault Site, midway between Georgetown and Fort Cavazos.
