Physics of A Coaster essays

Physics of A Coaster essays Individuals love to go to the amusement parks and try out the rides that are available. The most common and thrilling ride is the roller coaster. An amusement park is not an amusement park if it does not contain a roller coaster. What makes these roller coasters so fun that every amuse parks has one. A lot of people would say it is their extreme high speeds that makes it very exciting. That is a valid answer, but it is the wrong answer. The speed has nothing to do with the excitement. It is more than likely that most people travel faster on their ride along the highway on the way to the amusement park than they would in a roller coaster. Basically the thrill all comes from the acceleration and the feeling of weightlessness that they produce. Roller coasters thrill people because of their ability to accelerate them downward one moment and upwards the next; leftwards one moment and rightwards the next. How does this thrill machine work? There are two ways that this question w ill be answered. First, through the basic principles and then through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill, the cars possess a large amount of potential energy because they are elevated very high above the ground. The potential energy depends on the mass and the height of the object. As the cars are released they lose a lot of their potential energy but they gain kinetic energy because all of the potential energy is transferred into kinetic energy. The kinetic energy depends on the...

The Principles of Possessives

The Principles of Possessives The Principles of Possessives The Principles of Possessives By Mark Nichol The rules about forming possessives can seem confusing, especially because forms differs according to which style manual a publication is following. But the primary styles are relatively simple. In this post, I will refer only to the two prevalent styles in mainstream publishing: that of the Associated Press Stylebook, the resource of record for American newspaper publishing, as well as some magazines, many websites, and various other forms of written communication, and The Chicago Manual of Style, the bible of American book publishing, as well as many general-circulation periodicals. Guides for certain academic and scholarly subjects may differ. AP Style Newspaper style is simple and minimalist: To form a possessive construction from a singular common noun, add an apostrophe and the letter s: â€Å"The girl’s hair is red.† However, if the noun ends in the letter s and the following noun begins with an s, add an apostrophe only: â€Å"The waitress’ smile was infectious.† Treat a proper noun the same as a singular common noun: â€Å"Jim’s car ran out of gas.† But if a proper noun ends in s, add an apostrophe only: â€Å"Lewis’ training regimen is impressive.† If a plural noun ends in s, use an apostrophe only: â€Å"Cats’ claws are retractable.† If the plural does not end in s, use an apostrophe and an s: â€Å"The men’s room is to the right.† If the possession applies jointly to two singular nouns, apply the apostrophe and s only to the latter noun: â€Å"Green eggs and ham’s popularity has declined.† (In this sense, â€Å"green eggs† is plural in construction but singular in meaning; it’s a menu item, not a grouping of eggs.) But if the two nouns are distinct, apply the appropriate possessive form for each noun to that noun: â€Å"My hat’s color and my shoes’ color match.† Chicago Style Book style is simultaneously more complex and more consistent: No exception is made depending on whether singular nouns preceding and following the apostrophe end and start with s, respectively: â€Å"The waitress’s smile was infectious.† (However, all plural nouns are treated the same as in AP style.) Some ambiguity occurs, though, with traditional expressions following the â€Å"for (blank) sake† form: When the noun ends in an s, an apostrophe alone is employed (â€Å"For goodness’ sake, put on some clothes!†), while expressions with singular nouns follow the normal style: â€Å"For expedience’s sake, I faxed the form.† Better yet, in this case, relax the expression: â€Å"For the sake of expedience, I faxed the form.† The primary difference in style between the two resources is that singular proper nouns are always followed by an apostrophe and an s, even if they end in s (or x or z). For plural forms of proper names, however, if the name ends in one of these letters, add an es and an apostrophe: â€Å"We saw the Thomases’ house.† Otherwise, add an s and an apostrophe only: â€Å"We found the Smiths’ cat.† In the most recent edition of the manual, the style for two special cases has changed: Words ending in an unpronounced s are treated the same as words with a normal s sound (â€Å"Dubois’s translation is better†), as are words ending in an -eez sound (â€Å"Xerxes’s defeat was definitive†). However, common nouns plural in form but singular in meaning take an apostrophe only: â€Å"Economics’ complexities are daunting.† The same is true of proper names: â€Å"The Rocky Mountains’ discovery by European explorers prompted exploitation of mineral and other natural resources.† However, many writers find these constructions awkward, and prefer to relax the constructions: â€Å"The complexities of economics complexities are daunting†; â€Å"The discovery of the Rocky Mountains by European explorers prompted exploitation of mineral and other natural resources.† The distinction in AP style between joint possession and separate possession (see the last paragraph in the previous section) also applies to Chicago style. Some other special cases include possessives with the genitive form (â€Å"Three hours’ delay made all the difference†); a possessive form of a phrase that appears attributive (â€Å"The farmers’ market has a wide selection of tomatoes,† but â€Å"I have a Diners Club card†); and plurals of publication and composition titles. In the case of such titles, if it is italicized, add an apostrophe and an s (â€Å"I read the New Yorker’s article about it,† but, because the following title ends in an s, â€Å"The New York Times’ editorial supports the bill.†) If quotation marks are called for, relax the construction: â€Å"The first line of ‘My Life in Verse’ appropriately describes her birth,† rather than â€Å"‘My Life in Verse’’s first line appropriately describes her birth.†) Possessives followed by a gerund a present participle (a type of verb ending in -ing) acting as a noun should use an apostrophe and an s if singular (â€Å"The doctor’s telling of the story was interrupted†) and an apostrophe alone if plural (â€Å"Doctors’ taking on of more responsibility are a factor†). It might be better, however, to revise the sentence in such cases: â€Å"The doctor’s account of the story was interrupted†; â€Å"Quality of care is affected when doctors take on more responsibility.† Also, this grammatical structure should not be confused with the similar participle form, which is not possessive: â€Å"Doctors taking on more responsibility are likely to offer a lower quality of care.† The apostrophe is optional when a noun (or a pronoun) follows a preposition: â€Å"They thought of their friends moving away as a personal affront† could also be rendered â€Å"They thought of their friends’ moving away as a personal affront,† where moving refers to an act of moving that â€Å"belongs† to their friends.

The War in Vietnam Dramatically Affected American Foreign Policy Essay

The War in Vietnam Dramatically Affected American Foreign Policy - Essay Example The War in Vietnam Dramatically Affected American Foreign Policy There was a significant increase of the focus on American foreign policy by the then president Lyndon Johnson after the conflict in Vietnam (Gallagher, 1). However, there were issues regarding statistics depicting that there were cases of racial discrimination; the foreign policy in America has undergone significant changes for a period leading to a reflection on their national interests. In fact, these changes were experienced after new revolutionary war, whereby America’s principal national interest was aimed at maintenance of independence from various countries in Europe. For instance, America has developed a significant foreign policy, which is supported by the Atlantic Ocean and typified through Monroe Doctrine. This foreign policy focuses on imposing constraints on European attempts to further colonization of the western hemisphere. Apparently, in America, formulation of these policy focuses on avoiding entanglement with other countries, thereby concentrating on developm ent of a nation covered the continent. These foreign policies have played a significant role in facilitating the process of industrialization, which focused on the foreign markets and colonies. Moreover, America managed to attain a minor level of imperial power by the end of twentieth century through war with territories such as Spain for Cuba, and with Philippines taking over Hawaii. (Mehmet, 1). On the other hand, the World War 1 involved Americans concerning European issues, though after the war, there was a form of isolation; for instance, Americans turned down the idea of joining the League of Nations, though it turned inward once again. Numerous issues and functions are taken by the foreign policy in America; for example, it focuses on establishment and maintenance of diplomatic relationships with other counties and international institutions such as United Nations (Mehmet, 1). The foreign policy has contributed in the process of maintaining peace, whereby America is able to work with their allies in a way that faci lities regional and international security. On the other hand, there are wide ranges of international economic issue that entail international trade and business that are affected by a change in foreign policy. Foreign policy has facilities involvement in issue such as aid and disaster relief, whereby American takes significant role of leadership these and other issue such as negotiation of treaties and maintaining peace. Therefore, America has taken an important function that involves seeking ways to address international economic and environmental issues. There are three branches involved formulation and implementation of foreign policy in America; in fact, these branches collaborate with necessary governmental institutions and agencies. On the other hand, this process involves the president and executives branches with the ultimate role of formulating and implementing

Nursing Research Paper PICO formated question Example | Topics and Well Written Essays - 1500 words

Nursing PICO formated question - Research Paper Example A terminal prognosis is generally not disclosed in Asian countries where passivity and acquiescence to authority are important traditions. Conversely, the same prognosis would usually be approached openly in the US and the UK and many European countries where autonomy and free will are widely valued. This paper aims to explore, analyze and find a way to better communicate terminal diagnosis and related prognosis to affected patients and their families. Attitudes related to disclosure of terminal prognoses have shifted dramatically in the Western healthcare tradition, including the UK, over the past four decades (Chochinov et al, 2000). Research conducted in the 1950s and early 1960s revealed that only 10%-31% of physicians routinely disclosed a diagnosis of cancer to their patients (Fitch, 1994; Thomasma, 1994). This practice was due in large part to the widespread belief that such a diagnosis would create severe emotional disturbances that could potentially lead to suicidal acts (Thomasma, 1994). However by the late 1970s, nondisclosure practices had reversed (Fitch, 1994; Thomasma, 1994). This is evidenced by the 1979 survey results of Novack et al. which indicated that 98% of physician respondents disclosed the presence of terminal illness to their patients (qtd in Field and Copp, 1999). Comprehensive aspects of end of life medical care have been brought to public attention through the development of both health psychology and behavioral medicine. Each field has made a unique contribution to the understanding that physical health is impacted by numerous biological, psychological, and sociological elements. The upsurge of interest in these biopsychosocial interactions led to an increase of studies in many areas, including that of coping with, and adjusting to, life-threatening illness (Fitch, 1994). Findings generally indicate that given appropriate psychological and social support, disclosure of terminal prognoses does not lead to permanent loss of hope or untimely medical decline (Fitch, 1994), the reasons most often cited for the maintenance of nondisclosure practices. Moreover, attitudes toward truth-telling in terminal illness have also been significantly affected by the biopsychosocial approach to end of life care found in hospice organizations. The hospice move ment arose out of a need for palliative care for those whose needs were unmet by a medical system whose primary focus was prolonging life at all costs (Chiu et al, 2000). Hospice care has been a welcome alternative to traditional end-of-life practices (Chiu et al, 2000). In their analysis of shift from diagnosis non-disclosure to disclosure, Fields and Copp (1990) indicate the following reasons: (1) improvements in therapeutic success; (2) changing societal attitudes; and (3) in the USA, legislation enforcing the patient's right to "informed consent" (p.461). From the critical perspective, no one wants to be the bearer of bad news and there is a great deal of tension surrounding the complex issues of whom to tell, what to tell, when to tell, and how to tell about the existence of a terminal prognosis (Fitch, 1994). Physicians frequently believe that it is their duty to have ready answers for every possible question,

Sociolinguistics and Fairy Tales; An Integrated Approach to Adult ESL

Rationale The purpose of this study is to consider the current materials adult ESL students’ use and incorporate authentic material (through the use of fairy tales) as a way of helping adult learners achieve proficiency in second language through a mock prospectus. This study investigates the sociolinguistic, sociocultural and psychological features found in fairy tales, including Grimm’s tales, and the potential of using modern fairy tales as practice material for ESL learners. It explores various dimensions of fairy tales and demonstrates how they can be used as content to instruct and provide language practice to ESL learners. Fairy tales are predominantly taught to native English primary school students. They are a ‘semi-logical’ language that is inherent to the English language. Teachers can use similar texts so that adult ESL students can benefit becoming familiar with certain grammatical structures and vocabulary. It is essential to discover whether adult ESL students can comprehend the language used in fairy tales. Therefore, the following hypotheses can be made; Are the linguistic features in a modern fairy tales similar to standard/basic everyday texts? Do these texts have the potential to be authentic enough for standard language use? Can these texts allow students to be more active and confident in their English proficiency and self-development? What problems can occur if the mock prospectus is implicated? The main theory used in this study will be Krashen’s Input Hypothesis; the ‘i’ as the students’ familiarity with the stories and the +1 as the target language acquired. Teachers must provide students with opportunities to use meaningful language and, allow for immediate corrective feedback. Storytell... ... Little Pigs’ New York: Viking.

Humanities Paper Essay

Humanities is a topic that has so many wide-ranged meaning in regards to historical literature and arts. After conducting much needed research on the topic at hand, the author will discuss their informational findings in a research paper. In this paper, the author will define the meaning of humanities, discuss a cultural event that has been experienced such as music, dance, theater, art, literature, etc. The author will then elaborate on how a particular event was an expression of what he/she knew about the humanities, art, style, genius, and culture of the time  period it represents. Finally the author will explain how the selected form of cultural expression compares with other forms he/she know about from the same time period. Hopefully after reading this paper, the audience will have a better knowledge about Humanities in the Past, Present, and Future. Humanities Humanities can be very abroad, but one of the meanings of humanities, according to the American Heritage Dictionary, is â€Å"Those branches of knowledge, such as philosophy, literature, and art, that are concerned with human thought and culture; the liberal arts† (American  Dictionary, 2000). Culture is a big part of humanities. These patterns, traits, and products are considered as the expressions of a particular period, class, community, or population (American heritage dictionary, 2000). Humanities has really helped paved the way for future endeavors such as the way we think, conduct ourselves, and the way we observe things. Select a cultural event you have experienced, such as music, dance, theater, art, literature, or others. 3 Defining the Humanities Paper Growing up in Louisiana, I have had the honor and pleasure of experiencing many  cultural events, but I must say my favorite cultural experience would have to be music. Music is one of the many ways I could escape from the turmoil in the world. In high school I was in the choir and my favorite instrument at the time was the piano. I use to lead the choir and sometimes, I was able to perform a solo piece while playing my piano. This was a great experience for me because I had an outlet to express myself without even speaking. My high school choir had the honor of performing at a nursing home in St. Francisville where there were a lot of singers,  ex-musicians, and dancers who were in the choir and performed around Louisiana just like my school. They really enjoyed our performance and they shared great stories about the times when they were in high school in the choir, and how music has changed since their days of playing music. Explain how your selected event was an expression of what you know about the humanities, art, style, genius, and culture of the time period it represents. I learned so much about the expression of humanities just by listening to the older  individuals talk about their experiences and the different ways they made music. They did not have the use of different instruments like we have now back in their day. These individuals made music with whatever they had and enjoyed every minute of it. They also expressed their concerns about the schools eliminating the music programs, they feel that they are taking â€Å"art† and â€Å"freedom of expression† away from our youth in the schools. Discuss how your selected form of cultural expression compares with other forms  you know about from the same time period. 4 Defining the Humanities Paper By listening to the elderly individuals at the nursing home it really gave me some insight on the cultural expression I chose which was â€Å"Music†. It showed me just by listening to each of them that music was relevant just as much then as it is now. They just had a different way of making music and expressing themselves while doing so. They made music with cups, buckets, washboards, keys, and anything that made some kind of noise. In today’s society, we now have  advanced technology which allows each one of us to have access to different instruments, such as the piano, guitar, drums, etc. Although the elderly individuals did not have access to the instruments we have today, they still appreciated what they had. Conclusion In conclusion, after conducting research on the topic at hand, the author discussed their informational findings. The author defined the meaning of humanities, discussed a cultural event that was experienced such as music, dance, theater, art, literature, etc. The author then elaborated on how a particular event was an expression of what he/she knew about the humanities, art, style, genius, and culture of the time period it represents. Finally the author explained how the selected form of cultural expression compares with other forms that he/she knew about from the same time period. Hopefully after reading this paper, the audience now have a better knowledge about Humanities in the Past, Present, and Future. 5 Defining the Humanities Paper Reference www. ahdictionary. com/.

Copd Chronic Obstructive Pulmonary Disease - 1179 Words

COPD, or Chronic Obstructive Pulmonary Disease, is one of the most common lung diseases. Thousands of people are diagnosed every year, and it recently moved up to the 3rd leading cause of death in the U.S., behind heart disease and cancer. This paper will discuss disease pathology, the most common and recently discovered diagnostic tests, as well as treatment options. It will also address end of life care. COPD is a multi-system and multi-symptom disease. This means that it attacks the respiratory system, primarily, as well as the cardiovascular system. It also produces several symptoms that can be disguised for other pathologies and diseases. It is a progressive disease, meaning that treatment generally consists of easing symptoms, not curing them. Since it ends up being a terminal disease, a large part of treatment and patient care is developed around quality of life and the final stages of the patient. Several tests have been a part of diagnosing COPD for many years, incl uding the most common, Spirometry. Spirometry is a lung function test that measures the total volume of air that the patient can expel from the lungs after maximum inspiration. Although this test is successful in helping diagnose COPD, it has been said to be overlooked more and more in primary care. Spirometry testing is essential, along with thorough examination and history taking, to avoid missed or late diagnoses.
