Car Accidents and Physics - 2070 Words

Every day, many Americans are hurt or killed in car accidents. Many factors can play into an accident. Road condition, mechanical failure, driver error, or simply an act of God? Despite the countless reasons for a car accident, one factor is always present, no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text, in science journals, and on the Internet, I will prove this to you. Take, for example, two cars traveling in opposite directions at 100km/h. One of the drivers dozes off and crosses over the centerline. The two cars hit head on. The driver of car A has remained inside the car and has broken ribs. The driver of car B, however, is on the hood of†¦show more content†¦This is a lot of force for one person. So I wonder how those parents with the unbuckled children in the front seat expect to hold back a child exerting 172.4 kg of force while they are trying to hold themselves from crash ing into the windshield with 949.5 kg of force. Newtons Third Law of Motion states that for every action there is an equal and opposite reaction force (Hewitt, 71). This law helps explain why a collision at low speed is less serious than one at high speeds. If a car exerts a small force on a brick wall due to low speed then the car and its passengers will experience a force of equal magnitude, but in the opposite direction. If cars of unequal mass collide the more massive car will force the smaller vehicle backwards and the smaller car will experience more force. This is due to the conservation of momentum. The Law of Conservation of Momentum states that in an isolated system the momentum before a collision is equal to the momentum after the collision, if we disregard friction (Hewitt 92, 93). So in the example above we can see that the smaller car gained the momentum lost by the larger car. If two cars of equal mass collide and all the potential energy is converted back into kinetic energy after the collision then the collision is said to be elastic. However if the twoShow MoreRelated The Physics of Automobile Accidents Essay examples580 Words   |  3 PagesThe Physics of Automobile Accidents Automobile accidents happen all around us.

Identifying with the Enemy free essay sample

In Jane Austen’s Pride and Prejudice, Caroline Bingley is a big, fat b-word. As a high school student, I feel justified calling her that, seeing as her attempts to command Mr. Darcy’s attention throughout the novel often stoop to the level of a high school girl (ahem, me, ahem). After all, Hell hath no fury like a hormonal teenage girl scorned. Still, I can’t help but sympathize with her. Here she is, a well-bred, well-to-do lady with a huge crush on this super hot guy. It’s like the basis for every problem that has ever occurred to me in high school. Then, out of nowhere waltzes in this uncivilized, pretentious, exercise-inclined girl and, suddenly, the man for whom you have nursed a particular soft spot is swept away with one look at her â€Å"fine eyes†. Yes, I understand completely, Caroline. Like you, poor Miss Bingley, I have coveted most fervently the boy of my dreams (blue eyes, dazzling smile, jaw line that could cut marble you know the type).

And yes, like you, Caroline, I have employed all my dastardly feminine wiles, including, but not limited to: gossiping about said girl, teasing said boy about said girl in hope to discourage affection, persuading my brother to not marry sister of said girl, despite their apparent adoration of one another. Alright, just kidding about that last one. In no way do I condone Miss Bingley’s actions. Quite the contrary, I’m all for Elizabeth and Darcy living happily ever after. I can just understand what it’s like to feel the keen sting of unrequited affection. Heck, that’s what high school is for. But don’t worry, Caroline. Some day you’ll find an equally well-connected young gentleman who will put up with your witchy ways. I can only hope the same fate for myself.

Willam Ramsay, biography of Essay Example For Students

Willam Ramsay, biography of Essay William RamsayWilliam Ramsay was born on the second of October, in the year 1852. William, and his parents, William and Catherine, lived in Glasgow, Scotland. William Ramsay performed his work in his native town, until 1870 when he went to Tbingen and earned his doctorate in 1872. When returned to Scotland later that year, he became an assistant chemist at the Anderson College in Glasgow. Eight years later, he was appointed principal and professor of chemistry at London University, which held until his retirement in 1913. Ramsays earliest works were in the field of organic chemistry. In his early experiments he showed that the alkaloids are related to pyridine, which he synthesized in 1876 from acetylene and prussic acid. Some of his first work was related with the study of a new Bismuth mineral, which was only recognized as a metal until the 18th Century. William Ramsay also verified Roland Etvs law for the constancy of the rate of change of molecular surface energy with temperature. Ramsay published his work in accordance to Dobbie, on the decomposition products of the quinine alkaloids. William was very successful and submitted many contributions to physical chemistry, being mostly on Stoichiometry and Thermodynamics. He also commenced the 1880s with his work with Sidney Young on evaporation and dissociation.

Ramsay and Rayleigh were communicating daily with their results to solve their curiosity of the unknown gas. Rayleigh determined that a liter of pure Nitrogen weighs 1.2505 grams, but a liter of Nitrogen gas generated from air, by removing the Oxygen, Carbon Dioxide, and the water vapor, weighed 1.2572 grams. This led to Ramsays prediction that there must be another unknown element. William and Lord Rayleigh devised a chemical reaction to remove Nitrogen and Oxygen from air. To isolate the unknown, they would repeatedly pass atmospheric Nitrogen over heated Magnesium. This would remove all of the real Nitrogen, intern leaving the solid, Magnesium Nitride or Mg3N2. When the two chemists performed this reaction, Mg + N? Mg3N2 + ?, the remaining gas which is approximately 1% of air, was named Argon from the Greek word for lazy or inactive. Ramsay and Rayleigh announced their discovery of Argon to the British Association in August of 1894. William Ramsay searched for sources of Argon in the mineral kingdom. He discovered Helium instead of Argon in a uranium-bearing mineral. Until this point, Helium was only known to exist on the sun. Ramsay determined that this element was in fact Helium by viewing the minerals bright yellow stripe under a spectroscope which corresponded with the Helium that is on the sun. Helium was originally named by Lockyer. This led Ramsay to believe that there is a new group of elements. Ramsay was guided by Mendeleevs periodic table and began work with the British chemist, Morris W. Travers. Argon was now available in much larger quantities, through experiments by Claude in Paris, by the fractional distillation of air. Ramsay prepared a large quantity of Argon and fractionated it. He isolated three new elements. The first was called Neon, meaning The New One. The second was named Krypton, meaning The Hidden One, and the third one was called Xenon, meaning The Alien One, or The Stranger. Each of the new elements were unique by examining their spectrum. Then in 1910, Ramsay discovered Niton, or Radon in the radioactive emissions of radium, which was the last of the noble gases. .u0519943430a548041a12984433906373 , .u0519943430a548041a12984433906373 .postImageUrl , .u0519943430a548041a12984433906373 .centered-text-area { min-height: 80px; position: relative; } .u0519943430a548041a12984433906373 , .u0519943430a548041a12984433906373:hover , .u0519943430a548041a12984433906373:visited , .u0519943430a548041a12984433906373:active { border:0!important; } .u0519943430a548041a12984433906373 .clearfix:after { content: ""; display: table; clear: both; } .u0519943430a548041a12984433906373 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0519943430a548041a12984433906373:active , .u0519943430a548041a12984433906373:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0519943430a548041a12984433906373 .centered-text-area { width: 100%; position: relative ; } .u0519943430a548041a12984433906373 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0519943430a548041a12984433906373 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0519943430a548041a12984433906373 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0519943430a548041a12984433906373:hover .ctaButton { background-color: #34495E!important; } .u0519943430a548041a12984433906373 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0519943430a548041a12984433906373 .u0519943430a548041a12984433906373-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0519943430a548041a12984433906373:after { content: ""; display: block; clear: both; } READ: Nuclear Weapons Essay ThesisSince the gases that Ramsay discovered, had remarkable inertness, or completely unreactive, led to their use for special purposes. Helium was used for lighter than-air crafts instead of Hydrogen because Hydrogen is highly flammable whereas Helium is unreactive. Also, Argon was used to conserve the filaments in light bulbs. The inertness of the gases contributed to the Octet Rule in the theory of chemical bonding. Linus Pauling believed that compounds of the noble gases should be possible. Ywis, in 1962 Neil Bartlett prepared the first noble gas compound which is Xenon Hexafluoroplatinate, XePtF6. Currently most compounds of the Noble gases have been found. William
