The formulation of Newton’s law of gravitation involving the gravitational constant did not occur until the late 19th century. The experiment was originally devised to determine Earth’s density, which Cavendish determined to be 5.48 grams per cubic centimetre—close to the modern value of 5.51 ...
gravitational constant Symbol: G . A universal constant that appears in Newton's law of gravitation and is the force of attraction between two bodies of unit mass separated by unit distance. It is equal to 6.672 × 10–11 N m2 kg–2. Predictions that G is decreasing very slightly with ...
As one knows, strong discrepancies are found between the different precise measurements of the gravitational constant carried out in Earth-based laboratories. While the precision is increasing in different laboratories and with various methods, these measurements are even more and more discordant. We ...
gravitation - (physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses ...

The acceleration due to Earth's gravity has a (roughly) constant value anywhere on the surface and points directly to the center of mass of the planet: g = 9.81 m/s2. Given this constant value, the only things you need to calculate GPE are the mass of the object and the height of ...
The paths oflightrays are also geodesics of space-time, of a special sort, called “null geodesics.” The speed of light again has the same constantvelocityc. In both Newton’s and Einstein’s theories, the route from gravitational masses to the paths of particles is rather roundabout. In...
