n. (physics) the universal constant relating force to mass and distance in Newton's law of gravitation [syn: universal gravitational constant, constant of gravitation, G]
Wikipedia
The gravitational constant (also known as "universal gravitational constant", or as "Newton's constant"), denoted by the letter , 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 general theory of relativity. Its value is approximately .
Usage examples of "gravitational constant".
Examples include the speed of light, Planck's constant (basic to quantum mechanics), the gravitational constant (basic to gravitational theory), the charge on an electron, and so on.
The acceleration due to gravity should always be written with a lowercase g, to distinguish it from the Newtonian gravitational constant, G, which is a measure of the strength of gravity everywhere in the universe, not merely on whatever world or sun we are discussing.
If you measured the deflection accurately and worked out the mass of the mountain, you could calculate the universal gravitational constant—.
Anthropic Principle merely notes that if the laws of Nature and the physical constants-such as the speed of light, the electrical charge of the electron, the Newtonian gravitational constant, or Planck's quantum mechanical constant had been different, the course of events leading to the origin of humans would never have transpired.
It is equal to the mass of the star, multiplied by the square of the speed of light, multiplied by twice the gravitational constant, if you must know.
The gravitational constant, the charge on the electron, Planck's constant&mdash.
Well, if I'm not allowed to add about ten Jupiter masses, or change the gravitational constant, I suppose I'll have to make the planet denser - hmm, that's an idea.
