Mechanics and Newton’s Law

For billion of years, the Earth has been tirelessly orbiting around the Sun. This repetitive motion was kept by the virtue of gravitational force. And for us to understand the whole story about this, we need not to travel away from the Earth. Instead we just study these things in our planet. We can study them by relating the motions of vehicles in a curved road, a plane making a landing on the airport, and many more. And we can understand all of these through Physics and its branch Mechanics. Physics is the study of the basic principles that include light and matter, in order to discover and understand these implications of these laws, we can use the scientific method. There assumptions that there are rules and guidelines that should be followed for the universe to function. And these rules are partially understood by human beings (Crowell 22). While Mechanics is the branch of Physics that deals with the study of motion, matter, force and associated relationships between them (Alinea et al 29). And about 300 years ago, a brilliant mind was able to understand and relate his studies to everything that is concerned and related to the unanswered questions about the universe. This man named Isaac Newton came up with different conclusions and theories that are now fully accepted by the science society. His experiments gave answers to those questions and he left us with more things to think and discover. When he was about 23 years old, Sir Isaac Newton developed theories about gravitation in 1666, he claimed that all things fall to the earth because of a force called gravity keeps everything to be attracted and pulled down to earth. This idea came up when he was seating below an apple tree, then suddenly an apple fell down to his head. And on that day on he wondered why everything falls to the earth. Sir Isaac Newton Concluded that the Force between two mass containing bodies is given by the formula: F=G x (mass1 x mass2)/ (r) (r) Where F= force, G is the gravitational constant which is 6.67 x 10-11 N m2 kg-2, M1 and M2 are the masses of the two objects, and r2 is the square of their distance from each other. This experiment determines the attraction of objects through their masses. We can relate this to large quantities like stars, planets and other heavenly bodies. And even humans have attraction of forces from other things but these forces are very small and negligible in nature. About 20 years later, in 1686, he presented his three laws of motions-the Law of Inertia, the Law of Acceleration, and the Law of Interaction. These laws are to define, study, and understand the principles of forces and their interactions with each other along with other aspects which include acceleration Gravity, mass, and velocity. The first Law of Motion is called the Law of Inertia. It states that when a body is acted upon by a zero net force, the velocity remains constant. This velocity can be either at zero or non-zero magnitude (Alinea et al 35). This means that an object at rest, when acted upon by a zero net force, the object remains at rest. And if a moving object is acted upon by a zero net force, the object remains at that velocity and direction Imagine a car moving in a straight direction, if you exert two equal forces on either sides of the car, which will cancel each other and the result will be a zero net force, the motion of the car will remain the same. And this is also true with objects at zero motion or at rest. A good example of this law in our daily life is when you are sleeping. Assume that when you sleep, you were at zero motion. And your wife suddenly pushed you to the other side of the bed, and the tendency for you is to fall on the floor because the force acted upon you was non-zero. If you have another person on your other side, and that person will exert a force equal to what your wife will exert at the same time but opposite in direction, you will surely not to fall. Newton’s second law of motion was the Law of acceleration. It states that a body acted upon by an external on-zero net force will accelerate. And the net force is mathematically equal to the mass of the body times the acceleration (Alinea et al 35). Newton also made an explanation to the tendency of an object to move when acted by an external non-zero force. He gave the formula F=ma, Where â€Å"F† is the force acted upon the object, â€Å"m† is the mass of the object, and †a† is the acceleration of the object due to the exertion of the force. Experiments also show that the acceleration is inversely proportional to the mass, given by the formula a=F/m. This law explains why objects move when they are hit. An example is the car accident of former senator Rene Saguisag. According to the news, the van of the Mr. Saguisag was hit by a truck and it went about 20 to 30 meters before going stop. The Law of acceleration can explained to what happened to the van. Because the van was hit only in one side, the tendency of the van is to move and accelerate in the direction of the external force acted upon it. Another example is when you are walking down a street and suddenly you was hit by a muscular man about 200 Kilograms, and the tendency is you will move according to the direction that man was going and you will be accelerating due to the force acted upon you by that man. It happens all the time, even between pre-school pupils. The last law of motion is the Law of Interaction. It was stated that if an object A applies a force on another object B, object B is also applying the same amount of force but in opposite direction. And that their net force is zero (Crowell 145). It means that if you exert a force or effort to an object, the object exert the same amount of force but in opposite direction. For example, if you open a door, the door exerts equal amount of force to effort you exert on it. Much like of†what you do to others, they do it unto you†. Now that these laws explain and answer our questions about the universe, we can now relate it from the simplest parts of our daily life to the most complex structure of the universe. And for further analyzing and continuous exploration of the still undiscovered mysteries of the universe, we can develop and sustain answers to future questions that will make us enlighten our minds. And we need to cooperate and be part of the growing family of science that rooted from the intuitive and curiosity of the human brain to gain more knowledge in order to attain the best for our lives. And if I am not mistaken, we deserve to be the beings that were created to be alive. And every mind has the will to understand the whole of life, and what lies behind all those mysteries. And maybe we can account that for our Creator. Works Cited Crowell, Benjamin. Newtonian Physics. California: Light and Matter, 1998 Alinea, Allan L., et al. General Physics I.

Importance of Reading Essay

Reading has at all times and in all ages been a source of knowledge, of happiness, of pleasure and even moral courage. In today’s world with so much more to know and to learn and also the need for a conscious effort to conquer the divisive forces, the importance of reading has increased. In the olden days if reading was not cultivated or encouraged, there was a substitute for it in the religious sermon and in the oral tradition. The practice of telling stories at bed time compensated to some extent for the lack of reading. In the nineteenth century Victorian households used to get together for an hour or so in the evenings and listen to books being read aloud. But today we not only read, we also want to read more and more and catch up with the events taking place around us. The various courses and classes being conducted in rapid reading support this belief. The amount of reading one should get through is of course nobody’s business. There is no end to it for there is a variety of subjects to read about. The daily newspaper or the popular magazine while it discusses topical issues and raised controversies, it also provokes thought and throws light on human nature. It brings the news of wars, rebellions, organizations, political stances, heroic deeds etc. , together and helps knit a world of some sort. There is then the serious reading undertaken for research and for satisfying one’s longing for knowledge. It may be a subject of scientific significance, or a subject of historic or philosophic importance – varying according to the taste of the person. This kind of reading disciplines the mind and trains one for critical and original thinking. There is yet another kind of reading -reading for pleasure. Though serious reading is also a source of pleasure, reading which is devoted mainly to it differs in one respect. It grows upon one, it gives before demanding and it soothes and relieves tension and loneliness. The only kind of reading which neither stimulates thought nor provides knowledge is one which is approached negatively, with the simple motive of escape and of â€Å"killing† time. A person who is widely read is able to mix with others: he is a better conversationalist than those who do not read. He can stand his ground. Reading broadens the vision. it is in a way a substitute for travel. It is not possible to travel as much as one would like to and reading can fill in the gap created by the lack of travel. â€Å"Reading†, as Bacon wrote in his essay. ‘Of Studies’. â€Å"maketh a full man: conference a ready man: and writing an exact man†. Thus a widely-read man is a better conversationalist and is able to see the other point of view. Literature is a form of art which can cross barriers and if one does not know the language in which a piece of literature is written, one is willing sometimes to learn the language. Even if one does not learn a language one reads the literary work in translation. This contributes to the growth of understanding and tolerance amongst people. Reading also helps one to see the present in relation to the past and the future, and thus develop a historical perspective. Care is needed to ensure that reading does not become a substitute for real life. The moment one ceases to enjoy the ordinary pleasures and happiness of life and is content to enjoy them vicariously through fictional and historical representations, one loses all the benefits of reading and loses contact with life. With the cinema and television taking up a great deal of attention of children, teenagers and even adults, the habit of serious reading is dying out. People are content to read abridged versions. see films, go through illustrated comics and be content. But just as reading should not become a substitute for the joy of living or drive out the other forms of entertainment, other substitutes should not be accepted for the pleasure of reading which lies in the act itself. One may be selective, may be discriminating but no one can afford to shut himself off from this rich and ever-growing world of literature.

Causes and Effects of the English Language Essay Creative writing (164) , English language (137) company About StudyMoose Contact Careers Help Center Donate a Paper Legal Terms & Conditions Privacy Policy Complaints In America, English is the national language. However, with many different cultures and ways of life, everyone doesn’t speak the same English. In the north, people tend to speak clearly and to some this is correct. In the south, people tend to tie their words together and to some this is incorrect. Ultimately, the question is, is what is good language what is bad and what causes the two. In Orewell’s piece, he criticizes the English language starting from the teachers who teach us on to the authors who entertain us. He emphasizes how bad language begins with those to people and their bad habits. He also stresses that if we â€Å"remain strong in this fight against bad English† then we will soon overcome the bad habits and whatnot. Orewell talks about dying metaphors and usage of words that aren’t in layman term. He suggests that when authors use common metaphors and uncommon scientific words, they are writing incorrectly. Consequently, readers and other writers are reading, writing, and learning incorrectly. In my opinion, Orewell’s essay was not efficient in any way. He was nothing short of a hypocrite doing what they do best. He speaks of creative writing and original methapors, but he uses neither. He speaks of using cumbersome words that nobody relates to, yet the majority of his essay was written as if he spoke old English. He doesn’t follow any of the rules that he strongly suggests will bring us out of this fight of bad English. He’s setting no example for the so-called unrightfully successful authors and novice writers. The English language has many different meanings, expressions, causes and effects. So many, that there can no be one specific person determining which are the most perfect. As stated before different regions of the U.S. determine how those people talk, so unconsciously people read and write the way they speak. Many authors use metaphors to allow the audience to better relate to the message their relaying. Many authors use scientific and uncommon words to help broaden their readers vocabulary and to expose them to more than they knew before reading their piece. These critical readers  pick up dictionaries and thesauruses and begin to further explore the language they’re so familiar with. Orewell is neither the most qualified nor perfect person to suggest how authors should write. After all, no on is criticizing his piece and how it negatively drew the audience in. If he is criticizing the way English is taught then he’s ultimately criticizing the way people interpret. Many people are doing just fine without Orewell’s negative views of the English language.

Should the government provide free public education to children of Essay - 3

Should the government provide free public education to children of illegal immigrants - Essay Example Arguments for Educating †¢ Moral justification since the children are underage and did not choose to be illegals †¢ Criminal potential; uneducated immigrants might become criminals in future †¢ The American dream, America should welcome those who are projected for fighting for its ideologies in their countries such as democracy †¢ Economic Social and Educational Value, immigrants can play a role in the developing the country as teachers or business people IV. Conclusion †¢ Educating of immigrants children has both positive and negative impacts †¢ The position of Americans on the issue has softened over time †¢ These children should be given a chance at a better future Four hundred years ago, America welcomed visitors and immigrants from all over the world, with the passage of time, generations of these people and their descendants became the citizens of the United States. However, of late, immigration has become thorny topic and the American borders are no longer open to all due to a myriad of demographic and security issues. For one to become a citizen, there is a long process to be followed, and few people have the patience or the means to follow this up. Despite the legal restrictions, America is still, in the eyes of many people a haven of prosperity and security, and this has resulted to illegal immigrants who cross over the border through either land or sea to try their luck in the states. President Obama through the Dream act gave immigrant’s children who have been brought up in America a chance to pursue their education, which was previously impossible due to legal restrictions (Orchowski, 2010). This has elicited a myriad of reactions from different quarters with some agreeing, but many set against this move. This paper is will discuss the two sides of the argument and attempt to argue out that the children of immigrants should be given a chance at an education in the United States. Americans opposing this ofte n have come up with several arguments to support their position; they include claiming that; allowing the children of these immigrants access to public education in America is self-defeating. This is because it implies that the American government is using taxpayer’s money to fund the US border patrol to keep out illegal immigrants, while at the same time educating their children from the same coffers. They argue that the education of immigrant’s children will drive up the taxes especially in view if the fact that their parents, who have no social security numbers, do not pay taxes, as such it is the taxpayer who will bear the whole burden. In addition, another argument is that the education of illegal immigrants is a slap in the face of those legal migrants who have worked hard and paid the taxes. Besides, immigrants might be an encouragement to come to the country purposefully, so that they can get an education hence, in the end, they will spur more immigrants to com e over escalating the illegal immigrants problems. To mitigate this, the Dream act covers only the children who had been in America before it was enacted, but admittedly, it will be hard to ensure it will not encourage future immigrants to cross over illegally. While one must concede that these arguments are valid largely, they do not tell the whole story; neither do they represent all the variables that arise when an immigrant’s child is educated in the states. At the need of the day, it is essential one considers the advantages of

A Good Impression of True Christianity Article Example | Topics and Well Written Essays - 500 words

A Good Impression of True Christianity - Article Example After spending time in regular prayer and meditation, Christians will eventually put to practice what they learn from God’s Word along with the promptings of the Holy Spirit. They will be â€Å"doers† of the Word and not â€Å"hearers† only for as the Bible says: â€Å"Faith comes by hearing and hearing of the Word of God.† Christians begin to practice what they preach by putting to action what they learn in their daily devotion and Bible Study. Finally, when more time is spent on prayer and meditation, people begin to spend less time finding faults in others and begin to love each other as real brothers and sisters in the Lord. In doing so, they refrain from backbiting that usually results in quarreling. The church will then become a â€Å"home† for the weary and brokenhearted. It will become a safe refuge from life’s trials and difficulties. If Christians follow these suggestions individually and as a congregation of born-again believers in Christ, the community will respect it and even be drawn to be part of it. What the world needs is a dynamic loving church that nurtures and understands not one that judges and bites. If Christians follow these suggestions individually and as a congregation of born-again believers in

WALMART'S OPERATIONS AND MANAGEMENT Essay Example | Topics and Well Written Essays - 500 words

WALMART'S OPERATIONS AND MANAGEMENT - Essay Example Market analysts are of the opinion that Walmart will retain its top position ("Turning Point"). With this trend, it seems that Walmart will definitely continue its dominance in the consumer market, at least in the foreseeable future. It definitely does not hve a problem with the number of retail stores it owns; in the United States alone,it has about 3900 retail outlets ("Annual Dividend"). Walmart is a very aggressive company, and is currently opening about 1.45 stores per day. Although Walmart shares have mostly not grown, it will most likely increase in the immediate future. In a research note, Edward Jones analyst David Powers said "We believe Wal-Mart's growth outlook remains favorable." Powers believes that by April this year, growth will accelerate to nearly 13%. (Van Riper) Walmart's main concern is its slow growth rate, although this seems to be a minor problem at the moment. In January 2006 Walmart's same-store sales growth was 4.7%, compared to the previous december's 2.2%. (Van Riper) It is interesting that Walmart has what is probably the world's largest computer database, in its 1000-person Information Systems Division. This database has a capacity of 460 terabytes, equivalent to almost half of the information on the Internet. (Bianco) Walmart is able to reduce payrol costs through automated generation and adjustment of work sch

Media in China Term Paper Example | Topics and Well Written Essays - 3000 words

Media in China - Term Paper Example This is entirely wrong. The Chinese people have revered the color red since ancient times . . . The color red represents life, vitality, youth, ardor, brightness, vividness, strength, fullness of life force. (Bandurski, 2011, para. 14) In a press conference last week, Chongqing mayor Huang Qifan announced that CTV could expect to lose 300 million yuan in advertising revenues due to its â€Å"red† makeover. The city will reportedly subsidize its local television channels under CTV at a rate of 150 million yuan. Purpose of the Study CTV’s revolutionary reform comes at a time when neoliberalism and the commercialization of media are the dominant and overwhelming platforms on which China is making its ascension atop the global economy. While the party-state has maintained its firm grip, and is gradually modernizing its methods of control, market forces have permeated and transformed every aspect of the media system. Party-state power is increasingly converging with the powe r of capital in the Chinese media through a series of intertwined processes of accommodation, appropriation, state-engineered market consolidation, and selective incorporation of private and foreign media capital (Zhao, 2004, p. 1). This fusion of party-state and market power has resulted in a media system that preserves the well being of the country’s political and economical elite, while silencing and marginalizing any and all opposition (Zhao, 2004).
