Borehole Measurement of the Newtonian Gravitational Constant

Science, 1987
It has been reported that the geophysically determined Newtonian gravitational constant is consistently larger than the laboratory value by 1 to 2% on the basis of gravity measurements in Australian mines. This discrepancy may have strong implications for the physics of gravitation.

Newtonian Gravitational Interaction

2019
This chapter is devoted to presentation of the classical, Newtonian approach to gravitation, both in the frame of discrete N-body systems and in that of regular, continuous, distributions of matter. After dealing with the study of a point mass object in a resisting medium we will introduce the one body, 2 body and general N-body problem in the ...

Newtonian spherical gravitational collapse

Journal of Physics A: Mathematical and General, 1980
The spherical collapse of gas clouds is reduced to quadrature by specifying the mass function n(r, t). Exact solutions for both shearing and shear-free flow are constructed admitting two-parameter equations of state. A generalisation of Ritter's theorem is proved which allows the shear-free collapse of index three polytropes.

Newtonian gravitational field theory

Il Nuovo Cimento B Series 11, 1972
This paper was inspired by Bondi’s formula for gravitational energy transfer, and recent work on this by Cooperstock and Booth. It concerns only Newtonian gravitation and aims at clarifying the concept of energy in this context. Use is made of gravitational energy density, suggested by Maxwell, but not acceptable to him since it is negative.

An extension of Newtonian gravitation theory

Il Nuovo Cimento B Series 11, 1975
The energy density of a Newtonian gravitational field is shown to be −g2/8πG, whereg is the local acceleration due to gravity andG the universal constant of gravitation. In the case of a spherically symmetric object this causes a departure from the inverse square law forg.

Status of the Newtonian Gravitational Constant

1988
During the past 20 years, there has been renewed interest in Newtonian gravity and, in particular, on the constancy of the Newtonian gravitational constant, G, in space and time. Curiosity alone has provided the classical motivation for studies of this very weak force.
