This chart shows the value of g in various metropolitan areas around the world. It can be downloaded directly to the classroom computer.
The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
The dwarf planet Pluto is included in the list of planetary system masses above because it is included in JPL’s planetary ephemeris for historical reasons. Data are from the 1994 IAU file of current best estimates unless otherwise noted.
In gravitational physics it is useful to employ a natural set of units called geometrized units or c = G = 1 units that give both the speed of light and the gravitational constant unit value. Setting. = c = 2.9979×1010cm s−1. = G = 6.6741×10−8cm3 g−1 s−2,

To determine the motion caused by the gravitational force, follow these steps: Identify the two masses, one or both, for which you wish to find the gravitational force. Draw a free-body diagram, sketching the force acting on each mass and indicating the distance between their centers of mass.
Gravitational constant, physical constant denoted by G and used in calculating the gravitational attraction between two objects, which is equal to G times the product of the masses of the two objects divided by the square of the distance between them. The value of G is 6.6743 x 10^-11 m^3 kg^-1 s^-2.
This database gives values of the basic constants and conversion factors of physics and chemistry resulting from the 2022 least-squares adjustment of the fundamental physical constants as published by the CODATA Task Group on Fundamental Constants and recommended for international use by CODATA.
