The Stability

In the present work we assume that in the atomic nucleus the gravitoelectromotive force (F_ge=GKMm/R^2) acts as responsible for the stability of nucleus and for the nuclear size, and that the potential energy related to this force be given by the ratio F_ge/2πR with R equal to the nuclear radius observed in the electron scattering experiments, obtaining surprising outcomes.The new approach offers an occasion for discussing about the physics and chemistry foundations, in particular about the meaning of the gravitational potential energy and about the nature of the atomic nucleus, which perhaps should be reconsidered in deterministic terms, rather than probabilistic ones.

In the present work, by moving from the assumption that the Sun (and all the massive bodies) produces, starting from a certain distance from it, attractive and repulsive gravitational forces at the same time, giving life to the movement of the planets around the Sun according to the same principle of pendulum, I managed to derive a perihelion precession formula, a black hole radius formula and, above all, a formula of the atomic nuclear radius, which was missing until now, all in excellent agreement with the observation and in a completely independent way of the Einstein’s theory of relativity.I have also shown that the nuclear radius formula can also be successfully used to predict the radius of neutron stars.Moreover I have found — always through the same principles that allowed me to achieve the above results, in particular through the modification of the Newtonian gravitational potential, in turn due to the different modus-operandi of gravity force — a formula of the non-decreasing orbital velocity of galactic stars, without considering dark matter.Then I have demonstrated the black hole is composed only of protons, and that it’s similar to the nucleus of the atom and, analogously, the galaxy is similar to the atom, since the stars moving around the central nucleus in the same way as the electrons move around the atomic nucleus. I have also found another similitude among atomic nucleus, black hole and neutron stars, namely the self-orbiting phenomenon existing in all the cases.From the mathematical findings obtained in the present work it has also emerged the existence, both at the microscopic and the macroscopic level, of the gravito-electric force (or, if one prefers, electro-gravitational force), resulting from the fusion of the gravitational force with the electrostatic one, working exactly in accordance with Newtonian mechanics, although modified by the introduction of a repulsive force in addition and in opposition to the attractive one, that makes us understand the universe works always in the same way, both in macro and in micro. Furthermore, by means of the theory here proposed, it has been possible to find a theoretical foundation to the Planck constant, to derive the photon mass, to derive the electron orbital radius, inner and outer, as well as to prove the existence of the gravito-electric radiations.It is also emerged the existence of the universal principle of specific asymmetry between gravitational potential energy and kinetic energy, as a cause of nuclear energy E = mc^2.In this perspective, the present work can represent a potential unifying way between the macrocosm and microcosm mechanics.

The Stability

1. In a former paper I have considered the effect of gravitation as a factor tending towards instability, in the case of a spherical nebula of gas. The object of the present paper is to investigate the analogous problem in the case of a spherical planet, the planet being supposed composed of solid or fluid matter. The main question at issue is the following. 2. So long as gravitation is neglected there can be no doubt as to the stability of an elastic solid; any displacement increases the potential energy, and an unstressed configuration of equilibrium is therefore necessarily stable. But when gravitation is taken into account, the gravitational energy may be either increased or decreased by a displacement from equilibrium, and if a displacement can be found which effects a decrease in the gravitational potential energy of amount sufficient to outweigh the increase in the potential of the elastic forces, then the equilibrium configuration will be unstable.

Abstract The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work–energy theorem. The superimposed plots of the kinetic energy, gravitational potential energy, and the total energy as respective functions of time and position demonstrate energy conservation quite well. The same results were observed from the plots of the potential energy against the kinetic energy. On the other hand, the work–energy theorem has emerged from the plot of the total work-done against the change in kinetic energy. Because of the accessibility of the setup, the current work is seen as suitable for a home-based activity, during these times of the pandemic in particular in which online learning has remained to be the format in some countries. With the guidance of a teacher, online or face-to-face, students in their junior or senior high school—as well as for those who are enrolled in basic physics in college—will be able to benefit from this work.

Walking humans conserve mechanical and, presumably, metabolic energy with an inverted pendulum-like exchange of gravitational potential energy and horizontal kinetic energy. Walking in simulated reduced gravity involves a relatively high metabolic cost, suggesting that the inverted-pendulum mechanism is disrupted because of a mismatch of potential and kinetic energy. We tested this hypothesis by measuring the fluctuations and exchange of mechanical energy of the center of mass at different combinations of velocity and simulated reduced gravity. Subjects walked with smaller fluctuations in horizontal velocity in lower gravity, such that the ratio of horizontal kinetic to gravitational potential energy fluctuations remained constant over a fourfold change in gravity. The amount of exchange, or percent recovery, at 1.00 m/s was not significantly different at 1.00, 0.75, and 0.50 G (average 64.4%), although it decreased to 48% at 0.25 G. As a result, the amount of work performed on the center of mass does not explain the relatively high metabolic cost of walking in simulated reduced gravity.

AbstractWe collected 27 outflows from the literature and found 8 new ones in the FCRAO CO maps of the Taurus molecular cloud. The total kinetic energy of the 35 outflows is found to be about 3% of the gravitational potential energy from the whole cloud. The feedback effect due to the outflows is minor in Taurus.

This chapter explores the ways that accretion onto a black hole produces energy and radiation. As material falls into a gravitational potential well, energy is transformed from gravitational potential energy into other forms of energy, so that total energy is conserved. Observing such accretion energy is one of the primary ways that astrophysicists pinpoint the locations of potential black holes. The spectrum and intensity of this radiation is governed by the geometry of the gas flow, the mass infall rate, and the mass of the accretor. The simplest flow geometry is that of a stationary object accreting mass equally from all directions. Such spherically symmetric accretion is referred to as Bondi-Hoyle accretion. However, accretion flows onto black holes are not thought to be spherically symmetric—the infall is much more frequently in the form of a flattened disk.

<p>The intermittent surge is the basic manifestation of viscous debris flow, which emerges universally over the world, especially exemplified by those in Jiangjia Gully (JJG), a valley famous for its high frequency and variety of debris flow surges. It has been found that the surges originate from various sources in the watershed, thus identifying the source areas plays a fundamental role in studying the mechanism and process of surge developing. Advancement of GIS provides an apparent convenience in geospatial analysis of the watershed, which is used as a dominate tool in this paper.</p><p>In this study the JJG is divided into 97 tributaries (sub-watershed) and the hypsometric analysis is performed for each, from which derive the height of inflection points and the gravitational potential energy, coupled with the fitted parameters of specific power function. Then the morphology parameters, including slope, roundness, vegetation and soil, are revealed in tributaries. Besides, spatial autocorrelation among tributaries is quantified both globally and locally through Moran’s I and Getis-Ord G<sub>i</sub>*, so that the HI spatial distributions are quantified and visualized. In particular, hot spots are conspicuously visible and highlight the geologic meaning of the HI when exploratory spatial data analysis is applied to the data distributions through local indices of spatial autocorrelation.</p><p>The results show that H-curves approximately present as S-shaped, and the integral values (HI) range from 0.18 to 0.69 and show positive relationship with both gravitational potential energy and the height of the inflection points. By the HI value, the tributaries are identified as in 5 phases of evolution. The younger tributaries (HI>0.49) make up the majority, which are expected to be the main possible sources for debris flows. Additionally, the slope distribution of tributaries all conform to the extreme distribution while the curves for the upstream, where the HI of tributaries generally manifest higher coupled with larger roundness, tends to skew to the right.</p><p>Finally the correlation between possible sources are explored through geospatial analysis. The spatial association in JJG provides an explanation of the debris flow source areas. Global spatial autocorrelation manifests significantly clustered (Moran’s I shows 0.449, passing the significance test) while tributaries with high HI value concentrate mainly in the Menqian Valley. Moreover, the drainage form of Menqian Valley represents a large possibility of debris flow source area with the respect of that being in Duozhao Valley.</p><p><strong>Keywords: </strong>debris flow source area; hypsometric analysis; topographical characteristics; spatial autocorrelation; evolutionary phases</p>
