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 vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given … 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 See more Gravity acceleration is a vector quantity, with direction in addition to magnitude. In a spherically symmetric Earth, gravity would point directly … 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 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 … See more From the law of universal gravitation, the force on a body acted upon by Earth's gravitational force is given by $${\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}=\left(G{\frac {M_{\oplus }}{r^{2}}}\right)m}$$ where r is the … See more • Earth sciences portal • Escape velocity – Concept in celestial mechanics • Figure of the Earth – Size and shape used to model the Earth for geodesy • Geopotential – Energy related to Earth's gravity See more WebNone of these.
