Momentum Essays - Mechanics, Classical Mechanics, Collision

Momentum Conservation of Momentum Kristin Favreau October 26, 1999 Purpose: To show that momentum is conserved in a closed system by illustrating the conservation of momentum in an elastic collision and an inelastic collision. Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved. 1.) Elastic collision: A strobe photo will be used that shows a large glider smashing into a smaller glider which is initially at rest. This will cause the smaller glider to move and the large glider will continue to move also. 2.) Inelastic collision: A strobe photo will be used that shows a glider smashing into another glider which is initially at rest. When they collide the two gliders will stick together and will move. -The masses, distances and times will be measured in order to calculate the momentums of the systems before and after collision occurs. Data: V = d/t P = m x v 1.) Elastic collision: When Mass Distance Time Velocity Momentum Glider A Before Collision .31215 kg .009m .6s .015 m/s .00468 Kg m/s Glider B Before Collision .15580 kg ? ? 0 m/s 0 Kg m/s Glider A After Collision .31215 kg .005m 1.0s .005 m/s .00156 Kg m/s Glider B After Collision .15580 kg .011m .6s .018 m/s .00280 Kg m/s 2.)

Elastic collision: Before After Glider A .00468 Kg m/s .00156 Kg m/s Glider B + 0 Kg m/s +.00280 Kg m/s .00468 Kg m/s .00436 Kg m/s 2.) Inelastic collision: Total momentum before = Total momentum after mv + mv = (m + m ) v (.3105kg x .016 m/s) + 0 = (.3105 kg + .3000 kg) x .008 m/s .0050 Kg m/s = .0049 Kg m/s Conclusion: Through experiments with strobe photos involving elastic and inelastic collisions, I was able to show that momentum is contained within a closed system. My efficiency for the elastic collision was 3.54% and my efficiency for the inelastic collision was 1.01 %. Less than 10 % of the momentum was lost in either collision indicating a good experiment. The lost momentum can be attributed to the transfer from mechanical energy to thermal energy. Sources of Error: 1.) The distances measured in the two strobe photos were estimated. 2.) The measurement of time was an average. % error = difference x 100 sum of all 1.) % error = .00032 x 100 = 3.54 % error .00904 2.) % error = .0001 x 100 = 1.01 % error .0099

The Southern Defeat essays

The Southern Defeat essays It is often said that the south couldnt have won the civil war, well this essay is going to reflect the various ways in which the Southern states attempted to fight a losing battle from the beginning. The economic dependency of the South on cotton on slavery was well known, whereas the North had companies and technology. The advantage also lay with the North because of reasons such as better communication and transportation, and even more soldiers. The leadership in the North under Abraham Lincoln was more orginized than the that under Jefferson Davis. In the 1850's the North was more urban with a higher population due to all the Irish and German immigrants. By1860, almost all of the biggest cities were in the North. The North also had almost 3/4 of the railroads, and more telegraph lines to send messages instantly. The North had a lot more industry also, with its factories the north was able to mass produce guns, where as the plantations in the south were making.. cotton? well who do you think will win the war! (Source 1) The South had more slaves and more cotton. This was not any sort of military advantage as I said, and it just proved to the North how reliant the south was on them. The first attack at Fort Sumter was poorly organized and was expected by the North. Lincoln had wanted to attack, but kept the troops in moderation there so they didn't waste their men. This worked well because it worked out as he wanted and their were less casualties than their would have been if he had more of his men go. Once the war began, the military expertise of Ulysses S. Grant for the North made it an uphill battle for the South. His military skill alone was enough to give Robert E. Lee's forces in the South serious problem, but the Union army also greatly outnumbered the South's troops. Though Lee would prove to be a worthy general, his strategic downfall at Gettysburg would begin the destine loss for the South. (Source...

Slang, Jargon, Idiom or Proverb Explained

Slang, Jargon, Idiom or Proverb Explained Slang, jargon, idioms, and proverbs. What do they mean? Heres a short overview for English learners that explains and gives examples of each type of expression. Slang Slang is used by relatively small groups of people in informal situations. As it is used by limited groups of people, slang also tends to be confused with dialect. However, slang can be referred to as words, phrases or expressions used within a language, in this case, English. Also, slang is used by some to indicate words, phrases or expressions used by various ethnic or class groups. It should not be used in written work unless that work includes quotes that contain slang. This category of vocabulary changes rather quickly and expressions that are in one year, may be out the next.   Slang Examples emo - very emotional. Dont be so emo. Your boyfriend will be back next week. frenemy - someone you think is your friend, but you know is really your enemy. Has your frenemy got you worried? groovy - very nice in a mellow sort of way (this is old slang from the 60s). Groovy, man. Feel the good vibrations. (Note: slang goes out of fashion quickly, so these examples might not be current.) Recommendation You can use the urban dictionary for definitions of slang. If a phrase is a slang, youll find it there. Jargon Jargon could be explained as slang for business or enthusiasts. Jargon can be defined as words, phrases, or expressions that mean something specific in a particular profession. For example, there is a lot of jargon associated with the internet.  It can also refer to specific words used in a sport, hobby or other activity. Jargon is known and used by those who are on the inside of a business or of some activity.   Jargon Examples cookies - used by programmers to track information on a users computer that has accessed the internet. We set a cookie when you first access our site. birdie - used by golfers to state that the golf ball was put into the hole with one less golf stroke than expected on a hole. Tim got two birdies on the back nine at the golf course. chest voice - used by singers to indicate a style of singing that has chest resonance. Dont push so hard with your chest voice. Youll hurt your voice! Idiom Idioms are words, phrases, or expressions that do not literally mean what they express. In other words, if you were to translate an idiom word for word in your own language, it most likely would not make any sense at all. Idioms are different than slang as they are used and understood by almost everyone. Slang and jargon are understood and used by a smaller group of people. There is a wide variety of idiom sources on this site for English learners.   Idioms Examples rain cats and dogs - rain very heavily. Its raining cats and dogs tonight. pick a language up - learn a language by living in a country. Kevin picked up a little Italian when he lived in Rome. break a leg - do well at a performance or presentation. Break a leg on your presentation John. Proverb Proverbs are short sentences known by quite a large part of any language speaking population. They tend to be old, give advice, and be very insightful. Many proverbs are taken from literature, or from other very old sources. However, they are used so often that the speaker does not realize who originally said or wrote the proverb. Example Proverbs The early bird gets the worm - start working early and you will be successful. I get up at five and do two hours of work before I go to the office. The early bird gets the worm! When in Rome, do as the Romans - when you are in a foreign culture, you should act like the people in that culture. Im wearing shorts to work here in Bermuda! When in Rome, do as the Romans. You cant always get what you want - This proverb means what it says, you cant always get what you want. The Rolling Stones knew how to put that to music! Stop complaining. You cant always get what you want. Learn to live with that truth!

War of 1812 Essay Example | Topics and Well Written Essays - 500 words

War of 1812 - Essay Example Similar to the War of Independence (1775-1783), the war of 1812 was a result of conflicts between the Great Britain and the USA over spheres of influence and power on the American continent. During the War of Independence, the Thirteen colonies overthrew the British rules and established a new state governed by the American people. During the revolutionary years, the Declaration of Independence was promulgated (1776). Nations desiring to achieve these beneficial ends will agree, therefore, that no part of the American union ought ever to be subjected again to foreign rule2. The American Revolution and the war of 1812 changed international relations and opened new opportunities for international trade. The American government received a chance to trade with the rest of the world and supply cotton, tea and other goods to the Old world. Spain did not fear the rising power of the independent United States as it had when the colonies were an extension of British imperial power3. Both wars had similar battles and military strategies applied by the US Army leaders. The main military confrontations took place in Quebec, Massachusetts, Great Lacks and New York. The result of the wars was that fforeign trade improved economic conditions of the United states and increased the state budget.

Indecision, Hesitation and Delay in Shakespeares Hamlet Essay

Hesitation in Hamlet   Ã‚  Ã‚  Ã‚   William Shakespeare's Hamlet is tragic because all of the enmity being the product of one man's inability to make decisions. I believe the play is showing the steps of hesitation a person goes through who cannot choose, and the resultant angst. This one man is Prince Hamlet. Throughout the play he comes into situations where he just can't move himself into action. In Act I, Scene 5 Hamlet has an encounter with a ghost who explains that it is Hamlet's deceased father. After a little while of talking the ghost tells Hamlet that he did not die of natural causes, but was in fact murdered. When the ghost says this Hamlet replies with: "Haste me to know't, that I, with wings as swift As meditation or the thoughts of love May sweep to my revenge." (Lines 29-31) Hamlet is swearing to avenge his father's death as fast as possible. The ghost then tells Hamlet that the villain who committed the murder was the King's own brother Claudius. This surprises Hamlet, but he knows he made a vow and he must stick to it, he then says: "So, uncle, there you are. Now to my word: It is, Adieu, adieu, remember me. I have sworn't." (I.V. Lines 110-111) After the scene with the ghost the reader would most likely believe that an enraged Hamlet gone straight to Claudius' room to kill him. This is the first incident when Hamlet is observed being incapable of making decisions. In Act II, Scene 2, two scenes after Hamlet was about to kill the king, he still hasn't done it, but during this scene Hamlet comes in contact with a group of traveling actors and asks them to play for the king. Hamlet tells us in this next quote of his tragic flaw of indecision and of his plan ... ...gh out the play tearing at his soul. So in the end it was Hamlet's inability to act that kills him and many others. Works Cited and Consulted: Bloom, Harold. Modern Critical Interpretations Of Hamlet.

The Islamism: Origin, Ideology, Aims & Objectives

Nations around the world follows different ideologies to generate a direction for themselves. An ideology is a way of thinking, a set of beliefs, aims and ideas. It sets the vision for the group attached to it. Its purpose is to bring a specific change or carry out a certain task among its followers in accordance with a thorough thought process. When ideologies differ it gets difficult for the people belonging to a certain group to stay coherent. Ideological differences have triggered such events that were found to be powerful enough that they have shrugged the atlas several times. Wars had been fought by those who reject leading their life in the ways that conflicts with their own ideological beliefs. Islamic Ideology Islam is a religion of having faith in the oneness of God, finality of Prophet-hood, following the code of conduct according to the principles mentioned in the Holy Book and practicing the preaching of Holy Prophet. Islam emphasizes on building individual characters in an exemplary way so that a foundation of an ideal society could be laid. All Muslims have been ordered by their God Almighty to follow instructions prescribed in their Holy Book Quran, the purpose of this guidance is to lay down a way of life in which the laws mentioned in the book regulates a men’s relationship with other men and with his God. It provides a guideline for a man to maintain his social life along with his communion with the God. It indicates to a Muslim in his quest for knowledge, principle that enhances his capability to observe universe and nature with more understanding. Quran is not a book of science; it’s basically a book that deals with the basic principles of human life it preaches belief in oneness, immateriality, absolute power of the creator, charity for needy, brotherhood among mankind, subjugation of passions, the concept of accountability of human actions in the life after death, a system that teaches men to be grateful to all those who help and development of a sense of social consciousness by carefully performing those actions that are sensible and right and avoiding those that are forbidden and harmful for self and others. Islamism Islam provides Muslims a code of conduct that has been written in the Holy Book. Muslims are supposed to understand and follow it and when it comes to understanding there are different possible interpretations of the same text. Islamism is not a single concept rather it’s a product of different ideologies that exists within the umbrella of Islam. Islam is a religion that provides guideline for the Muslims around the world. Islamism has ideological conflicts. In general all these ideological groups call them Islamists, a group of people that completely rejects accepting secular governments and institutions and aim to align the entire world and its establishments in accordance to Sharia, the Muslim Law. One single society could have several directions of Islamism contributing to the fact that it’s been initiated by different groups trying to enforce their own ideologies and they seemed to never cooperate. Islamism expects its followers to align his life in complete adherence to the sacred law of Islam and completely rejects any foreign influences that may try to force any law or code of conduct that contradicts what is being mentioned in Islamic law. Islamism has in its root anger for non-Muslims and it condemn west to greatest extent. What it aims is to convert a religion into a kind of ideology. Origin of Islamism A little more than just 200 years before Muslim world was considered the hub of science and literature. Muslim scholars have laid such foundations that were later used by European researches to build extremely beneficial artifacts that have amazed the world. During the prime era of Muslims, there were mathematicians, doctors, scientists, philosophers, researchers and artists that people from around the globe used to come and learn from them. The theories presented by Muslim scholars are the basis of most of the modern scientific inventions and innovations. The downfall arose when the Muslim world interacted with the Europeans; its dated around 200 years back in 1798 when Napoleon landed in Egypt and the Muslim worlds came in contact with the Europe. From here came the influence and impact of European culture and civilization on the Muslims. The two nations are not incompatible but the ideological differences became evident when conflicts triggered events that lead to development of anger and hostile feelings among contradicting nations. According to Daniel Pipes: This confrontation was clearly shown in the aftermath of the fatwa by Ayatollah Khomeini against Salman Rushdie. Contrary to popular expectation, the lines in 1989 were drawn not between Muslim and Westerners, but between those who supported the ayatollah, or in some fashion sympathized with him, and those who were against him. One found many Muslims and Westerners on both sides. This illustrates how it is ideas that count, not religion. (Distinguishing between Islam & Islamism, 1998) The origination of Islamism is neither a single event nor responsibility of a particular person. It is the fundamentalist Islamic approach carried forward by those Islamic radicals that completely rejects the western culture and way of thinking. Series of events in history builds such anger among the Muslims that were once the most successful nation on the map of earth that they started to rebel and participate in destructive activities so that world could again come in their control, this time if not by education or technology then by force and devastation. Aims and Objectives There can’t by another explanation of Islamism but just that it’s like the other utopian schemes that have been proposed and adopted world wide and provides its followers ways and guidelines to control a state, take measures that help running a society and extend philosophies in order to re-make human beings inhabiting that state. The concept has been given an Islamic touch but over all it’s a totalitarian scheme. It embodied a complete transformation of the actual traditional Islam. It has an element of modernization, for instance it deals with issues related with a modern society, address problems arises in urban living and modern day women issues, and it provides guidance for the non-traditional problems faced by my occupations. It completely ignores Islamic principle of restricting laws and regulations to the individual and society rather it tries to inject geographically restricted rules in its effort to come at par with western style geographic law. It’s not a system that has evolved as result of poverty and money. It’s a reaction to modernization by those thinkers that try to find their own ways out in changing world environment and politics. Many educated people are Islamists and running their states according to their own ideology. Islamism has been evolved lately as a huge force that is responsible for running countries like Iran, Sudan and Afghanistan. In Algeria, Egypt, Turkey, Lebanon, and Palestine they exists as the strong opposition force. Though its been observed that Islamists are not in majority but even if they consists of minority it’s a very active one. The countries where they have establishments they are very successful and they not only run their own territories but they also interfere in their neighborhood and participate in overall world politics. Its been feared that if they grow their powers they will be responsible for contraction of economic stability, women oppression world wide, human right violation, terrorism and arms race. The ideas presented by Islamists belonging to different countries differ in ideologies and they are very difficult to predict. All Muslims are all well aware that they were the superior military and cultural force in the world for centuries, and the reversed situation in the modern ages hurts the pride of Muslims. As many Muslim countries have tried to copy both the capitalist system, and others the socialist system, and all have seen little but marginal success, Islamists are working for re-establishing what the promote as a â€Å"third alternative†; a political system that they claim is similar to the one which once made unknown tribes grow into becoming lords of empires in a few decades. But in order to create such a society, the Islamists are not rejecting modern technology, and are very concerned about implement this on a grand scale in an Islamist society. And because of the technology, the Islamists believe that the coming Islamist society will be an even better society than the one of the Golden Age. (Islamism, 2008) Even if what Islamists are trying is to bring the Golden period of Muslims back they are overlooking the fact that being intolerant, conservative and violent is something that was even practiced by Muslim rulers of history who ruled the world. A liberal Islam that encourages peace and harmony has always been the pride of a Muslim. Islam in its fundamental teachings promotes tolerance and love. Islamists have originated from people having moderate background living in cities. Mostly youngsters have are its prime followers. They don’t consider themselves to be the revolutionaries rather they say they are bringing the lost values back to the culture and society. Islamism condemns the economic system that world follows and suggests the Islamic economic system where interest rates should be replaced by investments made on profit and loss basis. When it comes to women they have contradicting views leading from conservatives to liberal. Sometimes they encourage women to work outside and sometimes they advocate women taking care of their families as their prime concern. The Islamist ideology could in no way support democracy, dictatorship is what they profess. A leader is responsible for listening to people’s problems and solving them accordingly. The Islamists have started to adopt a violent approach towards addressing different issues and demands for almost last two decades and are considered responsible for many destructive activities killing thousands of people worldwide. Nowadays, Islamists have been feared as a long term threat as there are growing powers day by day with more and more young people joining their force.
