the gravitational acceleration g is a function of position R, g(R), which at any point in space is given from a function Φ called the gravitational potential, by means of a generalization of the operation of differentiation: in which i, j, and k stand for unit basis vectors in a three...
There also has been a continuing interest in the determination of the constant of gravitation, although it must be pointed out thatGoccupies a rather anomalous position among the other constants ofphysics. In the first place, the massMof any celestial object cannot be determined independently of ...
Motivated mainly by the fact that no charged elementary particles having zero mass have been observed up to now, we investigate the question whether the mass of the elementary particles is connected with their electric charge and whether gravity can be derived from QED. The graviton is considered...

Density is the mass per unit volume of a material. Specific gravity is a measure of the ratio of mass of a given volume of material at 23°C to the same volume of deionized water. Film producers commonly report “Yield” on their specifications sheets. Yield is the area of film produced...
A point mass representation of a quasi-global gravity field of the moon is developed by processing Apollo 15 and 16 subsatellite and Lunar Orbiter 5 Doppler tracking data. The model is generated by reducing the long periodic variations in the mean orbit element rates. The gravity model consists...
Balanced and Unbalanced Circulations in a Primitive Equation Simulation of a Midlatitude MCC. Part II: Analysis of Balance. that the process of mass adjustment due to convective heating is largely dominated by unbalanced fast-manifold processes, such as inertia-gravity waves. The...

The body segments were manually separated by joints, and the software automatically calculated the average mass, volume, and center of gravity of the body segment, and the results were used to analyze the relationship between the body segments and the body characteristics and to build a regression...
We investigate the nonperturbative stability of asymptotically anti-de Sitter gravity coupled to tachyonic scalar fields with mass saturating the Breitenlohner-Freedman bound. Such ldquodesigner gravityrdquo theories admit a large class of boundary conditions at asymptotic infinity. At this mass, the asy...
Subatomic particle - Gravity, Quarks, Hadrons: The weakest, and yet the most pervasive, of the four basic forces is gravity. It acts on all forms of mass and energy and thus acts on all subatomic particles, including the gauge bosons that carry the force
