WebDec 7, 2016 · The force of Earth's gravity is the result of the planets mass and density – 5.97237 × 10 24 kg (1.31668×10 25 lbs) and 5.514 g/cm 3, respectively. This results in Earth having a gravitational ... Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s 2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s 2 at the surface of the Arctic Ocean. In large cities, it ranges from 9.7806 [6] in Kuala Lumpur , Mexico City , and Singapore to 9.825 in Oslo and Helsinki . See more The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a See more Gravity acceleration is a vector quantity, with direction in addition to magnitude. In a spherically symmetric Earth, gravity would point directly towards the sphere's centre. As the See more If the terrain is at sea level, we can estimate, for the Geodetic Reference System 1980, $${\displaystyle g\{\phi \}}$$, the acceleration at latitude $${\displaystyle \phi }$$: This is the See more The measurement of Earth's gravity is called gravimetry. Satellite measurements See more A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface. The Earth is rotating and is also … See more Tools exist for calculating the strength of gravity at various cities around the world. The effect of latitude can be clearly seen with gravity in high-latitude cities: Anchorage (9.826 m/s ), Helsinki (9.825 m/s ), being about 0.5% greater than that in cities near the … See more From the law of universal gravitation, the force on a body acted upon by Earth's gravitational force is given by See more incurred overtime
