The dimensions of the gravitational constant in the CGS system are [G]=[F][r]2/[m]2=(g.cm.sec−2)cm2/g2=cm3/g.sec2 and its value is G=6.67×10−8cm2/g.sec2. The extremely small value of G shows that the force of gravitational interaction can become considerable only for ...
The Newtonian gravitational constant G may be determined from a comparison of gravity at the ocean surface and at depth, where the attracting mass is smaller by an amount that can be determined from the measured density of sea water. Uncertainties arising from instrumental limitations and localized...
where G is the gravitational constant, r is the radius vector drawn from one MP to another being equal in absolute value to the distance between them. These forces govern the interaction between the heavenly bodies. A body on the Earth's surface (r = R, i. e., R is the distance betw...
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...
the value ofGremains same for each agent, which may cause inappropriate step size of agents for the next move, and thus leads the swarm toward stagnation or sometimes skipping the true optima. To overcome stagnation, we first propose a gravitational constant having different scaling characteristics...
where G is the gravitational constant, and H0 and Ωm,0 are the present values of the Hubble parameter and the matter density fraction, respectively. Here we adopt the best-fit values from the Planck data (H0, Ωm,0) = (67.27 km s−1 Mpc−1, 0.3156)10. Given the...
White dwarfs present an inherent method for constraining potential variations in the gravitational constant,G. This capacity stems from various factors. Firstly, white dwarfs possess exceptional longevity, making them sensitive indicators of even small rates of change inG. Secondly, as the final evolutio...

Recent theoretical interest in the possibility of observing a non-newtonian component of gravity arises from the lead that such observations will give to unification theories1. Absolute determinations of the newtonian constant G by geophysical methods, a
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...
