Abstract:
A new law of gravitational interaction is derived as an addition to Newton's law of gravitation. The additional force, which follows from the new law of gravitational interaction, refers to the Universe. This force is not given by the formula of Newton's law of gravitation. Newton's law is applicable to describe the gravitational interaction of point masses. The new law of cosmological force is applicable to describe the gravitational interaction of bodies with the Universe beyond the applicability of Newton's law of gravitation. The coupling constant in the law of cosmological force is the co

Abstract:
The main aim of this paper is to describe the problems that confront experimentalists who attempt to determine Newton's constant of gravitation, G . I will motivate this work by discussing the role of Newton's constant of gravitation in classical physics and recent ideas as to its role in quantum physics. I will then discuss some key aspects of a precision determination of G . This will include criteria for the selection of the detector of the gravitational torque from the point of view of random uncertainties due to read-out noise, thermal and vibrational noise.

Abstract:
Abstract Wide binary stars are used to test the modified gravity called Scalar-Tensor-Vector Gravity or MOG. This theory is based on the additional gravitational degrees of freedom, the scalar field G = GN (1+α), where GN is Newton's constant, and the massive (spin-1 graviton) vector field ϕμ . The wide binaries have separations of 2–30 kAU. The MOG acceleration law, derived from the MOG field equations and equations of motion of a massive test particle for weak gravitational fields, depends on the enhanced gravitational constant G = GN (1+α) and the effective running mass μ.

Abstract:
The tidal force is c secondary effect of the force Of gravity. It arises because the gravitational field is not constant across o body's diameter. When a body is acted on by the gravity Of another body, the gravitational acceleration con vary significantly between the necr side and the far side. This tends to distort shape of the body without altering its volume, Suppose that the gravitational field is due to one other body. Linearising Newton's law Of gravitation around the centre of the reference body yields an approximate inverse cube Along the axis through the centres Of the two bodies, th

Abstract:
A previous calculation of Newton's gravitational coupling constant G is generalized. This generalization makes it possible to have "atoms of two-dimensional space" with an integer dimension d atom of the internal space, where the case d atom = 1 is found to be excluded. Given the quantum of area l2, the final formula for G is inversely proportional to the logarithm of the integer d atom . The generalization used may be interpreted as a modification of the energy equipartition law of the microscopic degrees of freedom responsible for gravity, suggesting some form of long-range interaction betwe

Chapter 2 covers Newtonian dynamics, Newton’s law of gravitation and the motion of mutually gravitating bodies. The principle of least action is used to provide an alternative approach to Newton’s laws. Motion of several bodies is described. By analogy the same results are used to describe the motion of a single body in three dimensions. The equations of motion are solved for a harmonic oscillator potential. The general central potential is considered. The equations are solved for an attractive inverse square law force and shown to agree with Kepler’s laws of planetary motion. The Michell–Cave

Abstract The Universality of Physical Law begins to explore the breadth of nature’s laws that, like gravitation, extend beyond the confines of Earth; they are truly universal. An aspect of our Solar System that Copernicus, Kepler, and even Newton could not resolve was its absolute size; the first section moves past relative sizes to determining actual distances. The second and third sections consider the first measurements of two of nature’s fundamental constants, the speed of light and the strength of gravity as described by the universal gravitational constant while the fourth section consid

Abstract:
Abstract One of the consequences of Cartesian mechanicism was the discrediting of the idea that an innate and fundamental force of attraction accounts for sympathetic effects between substances. However, under the hegemony of Newtonian physics, chemists finally speculated that the force underlying chemical bonds was nothing other than a chemical force of attraction, similar to, though distinct from, Newton’s gravitational force. Unfortunately, the Newtonian theory did not account for either the selective nature of these chemical forces of attraction or their changing behavior under the influen
