Physics - General PhysicsA quantitatively verifiable expression for the gravitational constant is derived in terms of quantum mechanical quantities. This derivation appears to be possible by selecting a suitable physical process in which the transformation of the equation of motion into a quantum ...
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...

The possibility that the gravitational coupling "constant" G is an increasing function of the cosmic time t is discussed. In Section 1 the Maximal Power Hypothesis (MPH) stating that no power in Nature can exceed the upper bound c 5 / G (Gunn's luminosity) is advocated. In Sections 2, ...

Our moon is large enough to exert a gravitational pull that can be felt on Earth. The changing tides are the result of the moon's gravity pulling at Earth's water every day.Answer and Explanation: The gravitational constant on the moon is about 1.62 meters per second squared, much lower ...
The gravitational constant G according to the theory of NEWTON is the most imprecise constant of all physical constants. Moreover, there are a number of phenomena which suggest that this is caused by its invariant nature and the gravitation constant might be in fact a variable. In this article...

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...
