Earth's gravity constant
WebFor a spacecraft leaving earth, this can be said to occur at a height of about 5⋅107 5\cdot 10^7~5⋅107 5, dot, 10, start superscript, 7, end superscript, spacemeters above the surface which is about four times the Earth's diameter. At that height, the acceleration due to gravity has decreased to about 1% of the surface value. The gravitational constant is a physical constant that is difficult to measure with high accuracy. This is because the gravitational force is an extremely weak force as compared to other fundamental forces at the laboratory scale. In SI units, the 2024 Committee on Data for Science and Technology (CODATA)-recommended value of the gravitational constant (with standard uncertainty in parentheses) is:

Web3 Answers Sorted by: 7 The typical gravitational acceleration on the surface of the Earth, g ≈ 9.8 m / s 2, has uncertainty. That's one of the reasons why the ≈ symbol is used. The Earth's gravitational field varies a lot due to oceans, the thickness of the crust, mountains, non-uniform density in the crust and mantel, etc. WebApr 23, 2013 · The following animation displays the Earth s gravitational anomalies. The colors and heights represent the strength of gravity at the locality. Areas with less mass, such as ocean basins, show up as blue, that is less gravity, while mountains such as the Andes are red, representing the greater pull of gravity.
