Solar System and Gravity - 1112 Words

The Effects of Gravity There are some people who worry that when they re outside, if they don t keep a good grip on the ground, they ll just go flinging off into space. They needn t really worry about this, because gravity generally keeps that sort of thing from happening. The thing is, no one is really sure what causes gravity, but the effects have been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things falling down, weight, and the the moon and planets staying in their orbits. Things fall down. People have generally grown to accept that if one lets go of one s prized and valuable textbook when walking through a mud puddle, the book will invariably†¦show more content†¦So, too, the moon continuously falls around the Earth, and the planets fall around the Sun. Each of these objects balances the Sun s force of gravity with its own momentum, that is, with its innate tendency to keep moving in the same direction at the same speed. Take away the Sun s force of gravity, and the planets would sail into space, in whatever dircetion at whatever speed they happen to have. Take away a planet s momentum, perhaps with a giant hand that stops it in orbit, and it would head straight for the Sun, drawn by the Sun s gravitational force. But, because both gravity and momentum are at work, the planets fall, not down, but around, forever as they move in elliptical, but nearly circular, orbits. Working with insight that has never been exceeded since, Isaac Newton showed that by making one simple assumption, that all objects in the universe attract one another in accordance with a simple relationship, he could explain the fall of objects to the ground, the moon s orbit around the Earth, and the planets motions around the Sun. The relationship Newton conceived was this: Every object attracts every other object with an amount of force that varies in proportion to the product of the two objects masses, and in inverse proportion to the square of the distance between the centers of the objects. It is plain to see that gravity is quite important. TheShow MoreRelatedInterplanetary Dust and Orbital Debris1059 Words   |  4 Pagesdue to solar wind.

Current Correctional System and Rehabilitation - 934 Words

In 1929, the Federal Bureau of Prisons declared rehabilitation to be its fundamental goal. Do you think the current correctional system still holds rehabilitation as its number one goal? Why or why not? The goal of rehabilitation is an idealistic goal that is morally superior to the other possible goals of the correctional system. It was inspired by the belief that both inmates and society as a whole benefit more from the successful rehabilitation of convicted criminals than they benefit from punitive incarceration or by mere incapacitation (Schmalleger, 2009). After decades of social experimentation with criminal justice and corrections policies that incorporated and emphasized elements of rehabilitation over elements of punishment or mere incapacitation, the rehabilitation approach came to be widely perceived as having been a failure, largely by virtue of the very high recidivism rates of inmates during that time frame (Schmalleger, 2009). More recently, the American penal system s eems to have returned to the assumption that rehabilitating criminals is simply not a realistic goal on which to base national policies and practices. In the decades since the experiment with rehabilitation as the primary purpose of American penal systems, practices such as mandatory sentencing guidelines and three-strikes laws became more and more popular. In many respects, even judges have criticized the degree to which those types of laws limit their flexibility to apply judicialShow MoreRelatedThe United States Correctional System Essay830 Words   |  4 PagesUnited States Correctional System The United States correctional system is put in place for the time after a conviction to punish the convicted as well as get them ready to reenter society as a productive member.

Natural Disaster Volcanoes free essay sample

As it is forced up to the surface, the gases and magma push the earth up with it forming the mountain shape. When the magma gets near the surface of the earth it sometimes erupts violently, but can also erupt without violence. | | A volcano is actually an opening or a fissure, in the Earths crust, through which lava or molten rocks, ash and toxic gases present below the surface of Earth are discharged by a sudden, violent eruption. Sometimes, it can be a mountain-like structure with a bowl-shaped depression at the top, through which these substances are expelled. The term volcano is derived from the name of the Roman God of fire, Vulcan. Volcanic structures are usually formed at places where the tectonic plates are either converging or diverging. A stretching or thinning of the Earths crust, can also lead to the formation of volcanoes. They are often classified into three types, on the basis of their frequency of eruptions, i.

Sometimes they lie quietly for thousands of years in between eruptions. Some volcanoes have areas around them that experience earthquakes and release gases, but do not erupt with magma. | Â  |
