Red shows the areas where gravity is stronger than the smooth, standard value, and blue reveals areas where gravity is weaker. 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 Earth's figure is slightly flatter, there are consequently significant deviations in the direction of … See more If the terrain is at sea level, we can estimate, for the Geodetic Reference System 1980, $${\displaystyle g\{\phi \}}$$, the acceleration at … See more The measurement of Earth's gravity is called gravimetry.
