Orphan date February 2009 The Social gravity as an application of Newtonian gravity to the system of commerce ref http findarticles.com p articles mi qa4074 is 200607 ai n17182620 Social Gravity and the Translatio Tradition in Early American Theories of Empire ref influence. For instance in The Administration of the Colonies 1764 , Thomas Pownall 1722 1805 had used the Newtonian concept of attraction to form the basis of his political and commercial theory of empire. Pownall s vision provided an important explanation of the mechanism by which colonial theorists understood the possibility of empire being transferred from one state to another. Pownall applied the Newtonian concept of gravity to his theory of empire, as evident in his suggestion that the laws of nature held the colonies to Great Britain in a manner analogous in all cases, by which the center of gravity in the solar system held the planets in their orbits. In making this analogy, Pownall s notion of social gravity drew upon earlier visions of social cohesion, particularly ideas of sociability in eighteenth century Britain. These ideas, in turn, were often predicated upon Stoic notions of cosmopolitanism , expressed by the key term oikeiosis, in order to stress the moral imperative for like minded humans to forge bonds dedicated to the common good.

unreferenced article date June 2009 File Slant wagon.jpg thumb Slant wagon The Gravity wagon , or Slant wagon , is an angled hopper style wagon that utilizes gravity to make the unloading process easier. It is primarily used for on farms for agricultural purposes, such as for holding crops or fertilizer . For easy comparison, it is similar to a railroad hopper car , only with one door which is located on the bottom side rather than on the bottom center. Description A gravity wagon has three sides which are angled at about 45 degree angle degree s and one side that is vertical. An unloading door is located at the bottom of the vertical side where the three angled sides come together. This design causes the contents of the wagon to funnel towards the door so that no effort has to be put forth to unload the contents other than opening the door, which opens upwards by the action of a lever or turning of a wheel.

expansion . A gravity well or gravitational well is a conceptual model of the gravitational field surrounding a body in space. The more massive the body the deeper and more extensive the gravity well associated with it. The Sun has a far reaching and deep gravity well. Asteroids and small moons have much shallower gravity wells. Anything on the surface of a planet or moon is considered to be at the bottom of the gravity well. Entering space from the surface of a planet or moon means climbing out of the gravity well. The deeper a planet or moon s gravity well is, the more energy it takes to achieve escape velocity .

A ball s center of mass is not located on the surface but at a fixed distance r , which changes ... of a fixed size, this effect can be eliminated by constructing the surface so that the center of the ball ... shaped gravity well, and as in the rigid case a second test object placed near the first will gravitate toward it in an approximation of the correct force law. Gravity wells and general relativity ... s curvature of space. Although similar, this does not depict the Sun s gravity well. Both the rigid gravity well and the rubber sheet model are frequently misidentified as models of general relativity ... more details
