In the theory of general relativity , the equivalence principle is the equivalence of gravitational and inertial mass , and Albert Einstein 's observation that the gravitational "force" as experienced locally while standing on a massive body such as the Earth is the same as the pseudo-force experienced by an observer in a non- inertial accelerated frame of reference. A little reflection will show that the law of the equality of the inertial and gravitational mass is equivalent to the assertion that the acceleration imparted to a body by a gravitational field is independent of the nature of the body. For Newton's equation of motion in a gravitational field, written out in full, it is:.

The Center of Gravity Indicator

A spatial interaction is a realized flow of passengers or freight between an origin and a destination. Estimating flows between locations is a methodology of relevance to transportation. These flows, known as spatial interactions , enable to evaluate the demand existing or potential for transport services. They cover forms of mobility such as journeys to work, migrations, tourism, the usage of public facilities, the transmission of information or capital, the market areas of retailing activities, international trade, and freight distribution. Mobility can be physical passengers or freight or intangible information , and each form of mobility is subject to a form of friction.

The Center of Gravity COG indicator is a technical indicator developed by John Ehlers in , used to identify potential turning points in the price as early as possible. In fact, the creator John Ehlers claims zero lag to the price, and the smoothing effect of the indicator helps to spot turning points clearly and without distractions. Being a leading indicator, the Center of Gravity is used to anticipate future price movements and to trade on price reversals as soon as they happen. However, just like other oscillators, the COG indicator returns the best results in range-bound markets and should be avoided when the price is trending. The COG consists of two lines and is based on the sum of prices over a specified period. A simple moving average of the COG is plotted along the indicator to act as a signal line which generates buy and sell signals.

Equivalence principle

In physics , theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy. This work was furthered by ancient Indian and medieval Islamic physicists , before gaining great strides during the Renaissance and Scientific Revolution , culminating in the formulation of Newton's law of gravity. This was superseded by Albert Einstein 's theory of relativity in the early 20th century.

We propose a simple and relatively inexpensive method for determining the center of gravity CoG of a small spacecraft. This method, which can be ascribed to the class of suspension techniques, is based on dual-axis inclinometer readings. By performing two consecutive suspensions from two different points, the CoG is determined, ideally, as the intersection between two lines which are uniquely defined by the respective rotations. We performed an experimental campaign to verify the method and assess its accuracy. Thanks to a quantitative error budget, we obtained an error distribution with simulations, which we verified through experimental tests. Often developed as part of university educational programs, they have been dominating this segment in the last two decades. In this respect, it is known that accurate attitude and orbit control systems rely on the precise knowledge of the spacecraft CoG.

Although numerous studies have analyzed the relationship between manual material handling MMH and the forces acting on the lumbar spine, the difference in the MMH between experts and novices through the analysis of measured data has not been well studied. The purpose of this paper was to analyze the difference in the MMH positions between ten skilled experts working at a freight transport company Group 1 and five unskilled novices without any experience Group 2 during asymmetric lifting. All the human subjects performed asymmetric lifting experiments with closed eyes; the experiments involved moving loads 6 and 18 kg to the left side. Time series data of the vertical ground reaction force were measured, using a Wii Balance Board, and then, the center-of-pressure CoP trajectories were calculated. The balance board was used for the measurement, because it was reliable, inexpensive, and portable and provided good repeatability even on rough surfaces, and all the information pertaining to the load and worker under various conditions was captured without any omissions. Under the 18 kg load condition, the CoP positions for Group 2 were located on the same side during left asymmetric lifting; however, those for Group 1 were located on the opposite side during left asymmetric lifting. Furthermore, under the 6 kg load condition, the load weight influenced asymmetric lifting for most subjects of Group 2 such that the CoP positions were located on the opposite side.

Information—Consciousness—Reality pp Cite as. Finally, the human mind faces its own nature. By extending the information-theoretic paradigm, the informational nature of consciousness is uncovered. This gives rise to the very first formal description of consciousness.

History of gravitational theory

No work of science has drawn more attention from philosophers than Newton's Principia. The reasons for this, however, and consequently the focus of the attention have changed significantly from one century to the next.
