gravitational constant n (General Physics) the factor relating force to mass and distance in Newton's law of gravitation. It is a universal constant with the value 6.673 × 10–11 N m2 kg–2. Symbol: G Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCo...
For example, once the gravitational constant is known, then coupled with the acceleration due to gravity onEarth, the mass of our planet can be calculated. Once we know the mass of our planet, then knowing the size and period of Earth's orbit allows us to measure the mass of thesun. A...
Determination of the Newtonian gravitational constant G from free oscillation and travel-time data for a spherically symmetric non-rotating Earth is shown to be inherently impossible as long as G is spatially constant. Since Earth densities are normalised by the laboratory value of G, one ...
We have obtained a value for Newton's gravitational constant (coverage factor of 1) of G=6.6656(6)/spl times/10/sup -11/ m/sup 3/ kg/sup -1//spl middot/s/sup -2/ with a combined standard uncertainty of 95 ppm. The method is based on a torsion balance which is servocontrolled ...
Cavendish used this to measure the gravitational force between the two masses to calculate the density of the Earth, which later led to a value for the gravitational constant. This was the first experiment to measure the force of gravity between masses in the laboratory. In order to measure ...
One Newton equals about 100 g on Earth. How many Newtons would a football weigh if it has a mass of 400 g? One can calculate the gravitational binding energy of a spherical object (such as the earth) as follows. Assume that the earth's density is a constant \rho = M(\frac{4}...

What percent of the Earth is the outer core? Did Kepler assume gravitational force was constant with distance? At what height above the surface of Jupiter is the acceleration due to gravity half its surface value? Use the equatorial radius of Jupiter in your calculation ...
[35] Use of a constant value of ρ = 2670 kg/m3, implies that the g1 terms may be computed based purely on elevation information, under the above assumptions and approximations. Wang [1998]implemented and compared three different techniques for the analytical continuation of the 30 arc-minute...
The Newtonian gravitational constant, G, is one of the most fundamental constants of nature, but we still do not have an accurate value for it. Despite two centuries of experimental effort, the value of G remains the least precisely known of the fundamental constants. A discrepancy of up to...
