Noun
(physics) the universal constant relating force to mass and distance in Newton's law of gravitation
Source: WordNetColloquially, the gravitational constant is also called "Big G", for disambiguation with "small g" ( g ), which is the local gravitational field of Earth (equivalent to the free-fall acceleration). citation. Source: Internet
In SI units, the 2014 CODATA -recommended value of the gravitational constant (with standard uncertainty in parentheses) is: citation citation : This corresponds to a relative standard uncertainty of main. Source: Internet
In the Kaluza theory, the gravitational constant can be understood as an electromagnetic coupling constant in the metric. Source: Internet
Cavendish's aim was not actually to measure the gravitational constant, but rather to measure Earth's density relative to water, through the precise knowledge of the gravitational interaction. Source: Internet
Thus, in Planck units, and other natural units taking G as their basis, the gravitational constant cannot be measured as it is set to its value by definition. Source: Internet
