Effect of Force and Mass on Acceleration Essay

Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships, my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a â€Å"frictionless track† where it was pulled by a string bearing mass over the edge of a table. In the first relationship tested, applied force and acceleration, mass was moved from being on the cart to being on the end of the pulley. My partners and I measured the acceleration with the LabQuest computer every time the cart was released. In order to test the relationship between mass and acceleration, my group added different amounts of mass to the cart and measured the changes in acceleration. From all of the data collected we concluded that force and acceleration have a direct, linear relationship. We also determined that mass and accele ration have an inverse, quadratic relationship. Background: When my lab partners and I started this lab, we came in knowing some background information on what we were doing and the concepts involved. We knew that we had to determine the relationships between acceleration in a system and the net force acting on the system. We also knew that we had to discover the relationship between acceleration and mass in the system. Some major concepts we had to understand prior to the lab were Newton’s Fist Law of Motion, acceleration, net forces, and inertia. Newton’s first law states that an object at rest will remain at rest, and an object in motion will remain in motion, with the same speed and direction unless acted on by an unbalanced force. This is important because we were aware that when an object is moving at constant velocity there is a net force of zero. This gave my group our basic understanding of acceleration, a rate of change of velocity over time; because we realized that when there is an unequal net force the object must be accelerating/ decelerating. This also allowed my group to understand how net forces work, which is especially important since this lab consists of net forces that are not zero. Because the track the cart rode on was considered to be â€Å"frictionless,† my group used our prior knowledge to assume that the only unbalanced force in the system was from the horizontal tension in the string. My groups’ understanding that inertia is an objects’ tendency to stay at rest and resist motion helped us during the lab as well. With this background knowledge we were able to perform the appropriate experiments to gain the correct results for our lab. Purpose: The purpose of this lab was to determine the relationship between mass and acceleration. Another purpose was to determine the relationship between the acceleration in a system and the net force that is acting on the system. We wanted to deepen our understanding of these relationships by proving already known theories for ourselves. Hypothesis: If the mass of the cart is kept constant but the net force of the system increases (hanging weight over the pulley), then the acceleration will increase. The acceleration will increase because a larger force will cause the object to move faster. This is because as the forces become more unbalanced in the horizontal axis the easier it is for an object to overcome its inertial tendency to stay at rest. However, if the mass of the cart changes but the force is kept constant, then the acceleration will decrease. This will happen because the heavier the object is the more force needed in order for it to move. Adding mass would increase the object’s inertial tendency to stay at rest. Lab Drawing: Procedure: To test the relationship between acceleration and force (constant mass) my lab partners and I set up a metal cart on a metal â€Å"frictionless† track. The cart had a string attached to it that ran over a pulley, alongside the edge of the table, where it was connected to a hanging mass (as the above drawing indicates). We hooked up a LabQuest data logger to the track in order to document the carts acceleration while being pulled by the hanging weight. My lab partners and I then placed two 500 gram blocks on the cart in addition to five 50 gram masses. On the end of the string hanging was a 50 gram mass. The cart was then released from its held position on the track, and the hanging weight caused the cart to accelerate. This acceleration was documented by the LabQuest data logger. My partners and I performed three trials and then found the average acceleration. Once the average acceleration was calculated, we took a 50 gram mass from on top of the cart to the hanging mass. The cart was released and the LabQuest data logger documented this new acceleration. We did this three times as well. My partners and I did this until all of the 50 gram masses were transferred from above the cart to onto the hanging string (6 different forces, 15 different trials). After this was completed we found the applied force by multiplying the hanging mass by 9.8 m/s2 (acceleration due to gravity). We then plotted the points and graphed the data to discover the relationship. To test the second relationship, mass and acceleration, my lab partners and I used the same cart and pulley set up on the â€Å"frictionless† track. We calculated the mass of the cart prior to adding any more mass, which was about 500 grams. Once we discovered this number we added five 500 gram masses to the cart. We released this cart three times, using a constant force, and had the LabQuest document the acceleration. We then found the average acceleration for the 3 kg cart. After, we removed one 500 gram mass from the cart. We released the cart three times with this new mass and found its individual and average acceleration. We repeated these steps until all of the 500 gram masses were removed from the cart, and then tested the cart with no added mass (6 different masses, 18 different trials). Once completed, this data was plotted and graphed, and the relationship determined.

5 Tips for Writing a Stellar Vanderbilt Supplement Essay

5 Tips for Writing a Stellar Vanderbilt Supplement Essay SAT / ACT Prep Online Guides and Tips Vanderbilt is one of the United States’ highest-ranking colleges. With an acceptance rate of just 10 percent, it’s ranked as extremely competitive. It’s no surprise- Vanderbilt is known for having a wealth of appealing programs, including its school of medicine, the Peabody College of Education and Human Development, and Blair School of Music. Because it’s extremely competitive, you’ll need to set yourself apart as a prospective student. That doesn’t mean just your grades and impressive extracurriculars; it also means writing a killer essay to go along with your application. In this guide, we’ll tell you everything you need to know about Vanderbilt’s supplemental essay, including some ideal topics, some pitfalls to avoid, and even some analysis of past Vanderbilt essays that have worked. The Vanderbilt Supplement Basics Vanderbilt’s application is fairly straightforward. They accept multiple application formats, including both the Common and Coalition Applications, as well as Questbridge. What application you use is up to you. There are many reasons to choose one or the other, but regardless of which application you pick, you’ll still be answering just one supplemental essay prompt from Vanderbilt. Choose whichever application works best for you. In addition to the essays required for your Common, Coalition, or Questbridge Application, Vanderbilt requires one supplemental essay. There’s only one prompt with a 400-word limit, so you won’t have to choose between prompts. However, having just one prompt means that you’ll need to put a lot of attention into making your essay as good as it can be. You only have one chance to prove yourself in your essay, so make it count! A little latte art never hurts. What Is the Vanderbilt Supplement Essay Prompt? Vanderbilt has just one prompt for their supplemental essay, which must be answered in 400 words or less. Please briefly elaborate on one of your extracurricular activities or work experiences. The question is straightforward- Vanderbilt is asking you to discuss one of your extracurriculars in depth. This doesn’t just demonstrate to the admissions office that you’re dedicated to your interest, but also that you have passions outside of school. Vanderbilt wants to know that you’ll bring something besides academics to campus, and this is the space to tell them about it. Keep in mind that Vanderbilt isn’t looking for a list of activities or just a short discussion of one of your extracurriculars. They specifically ask for one, but you have 400 words to cover- which means you should spend some time unpacking not just the activity itself, but why you do it and why it matters to you. Be thoughtful; really think about your activities and why you do them beyond that they look good on your college application. Don’t just pick the extracurricular activity that you think Vanderbilt would want to hear about. If you’re a champion Mathlete but you really feel fulfilled when you’re making short films with your friends over the weekend, you should be writing about the short films. If your short film was played at a local film festival but you find more meaning in the time you spend knitting, write about knitting! It’s not about being impressive here. Plenty of other applicants will be discussing their charity work or science team victories. Use this space to discuss yourself, and why the things you do matter to you. If the most impressive thing in your repertoire and the thing that’s most personally meaningful line up, great! But don’t feel like you can only write about things like academic success, leadership roles, or entrepreneurship. Write about what’s meaningful to you and Vanderbilt will see your personality- which is really what they’re looking for- shine through. Reading Vanderbilt essays that worked is like planting a seed for your own success. Vanderbilt Essays That Worked: Analysis Vanderbilt doesn’t use the same prompts from year to year, but that doesn’t mean that looking at past successful essays can’t be useful. Consider this one from an accepted Vanderbilt student: â€Å"Never help a child with a task at which he feels he can succeed,† Maria Montessori once said. School was about letting my curiosity lead me and teaching myself at my own pace. For example, at the start of 7th grade, I was handed the Algebra I book and told to complete it anytime in the next two years. I was intrigued to have a real textbook, but a bit overwhelmed, as the math looked like a foreign language. After reading a chapter, I’d take a stab at the problem set right away. It wasn’t about getting the problems right or wrong; it was about trying to understand the material. As frustrating as this process was, each time I conquered a new idea, my exasperation was transformed into new energy. I learned how to solve problems independently and to know when to ask others for help. ... When I did get to high school, I was surprised at how well prepared I was. My two strongest skills, time management and the ability to work well independently and in groups, mad e the transition easy for me. The Mesa Sands experience shaped me outside the classroom, too. One of my strongest qualities is trustworthiness. Because my school did not have a set structure or rules, I’ve in effect worked under an honor code from the time I was three years old. This essay was written for a different prompt, but the fact that it was successful shows you that it contains features that Vanderbilt likes to see. The writer of this essay discusses their education at a Montessori school, which doesn’t take the same approach to education as many other schools. Throughout, they refer to the school’s teachings and how they shaped their learning, not just but the things they were taught, but the way that they were taught. Not everybody had this same educational experience, but that doesn’t mean that you can’t use some of the same ideas in your own work. The writer draws a clear line between how they were brought up and the person they are now- you could do a similar thing by connecting the person you are with the activity you’ve chosen to write about. What have you learned about yourself because of what you do? The writer is also able to discuss academic strengths without referring to their GPA, which Vanderbilt is no doubt already familiar with. Instead, they discuss their strengths as traits, like adherence to an honor code, trustworthiness, and time management. More importantly, they write about where those traits come from- something you could easily do by referencing the importance of the activity you choose. What’s most important to take away from this essay is the way that the writer connects the experience of attending their unique school to the person they became. No matter what your education was or what activity you choose to write about, you can do a similar thing in your own essay! Don't be afraid of multiple drafts- they make the difference between a good essay and a great one. 5 Key Tips for Writing Your Vanderbilt Essay Vanderbilt is a prestigious school, but there are some essay standards that hold true no matter where you’re applying. Follow these steps to write an essay that’s sure to impress! #1: Start Writing Starting is the step that sounds the easiest, but it’s actually the hardest. No matter what you have to do to start writing, whether it’s freewriting, brainstorming, or just pumping out a first draft as fast as you can, you need to do it. At this point, don’t worry about quality or being impressive. Just get words down on paper so that you can edit them into shape later- if you spend too much time worrying about starting with a perfect beginning, you’ll never make it past that point. #2: Edit Step two is when you can start worrying about quality. Read your essay aloud and see if you can spot problems with word choice and flow. If you’re struggling to read it, change words and add punctuation as necessary. Also think about your overall point. Does it make sense? Are you able to trace your logic all the way through without a problem? If not, find ways to connect your thoughts from beginning to end. Be thorough in cutting extraneous words. 400 words isn’t a lot, and you’ll want to make sure you’re making your essay count by picking vibrant, active verbs and clear language. Don’t worry about being flowery or busting out the thesaurus, but do be sure that your wording doesn’t feel tired or dull. #3: Seek Feedback One of the best ways to find holes in your logic or other issues in your essay is to get others to give you feedback. Find people who want to see you succeed, but preferably not those who aren’t going to give you criticism if you need it. Teachers and other mentors are a good choice, if they’re available. Don’t feel like you have to use every piece of feedback you receive, but do consider all of it. Your essay should always be your own work, so try to rephrase suggestions in your own words or rewrite confusing passages how you would write them, not how others suggest. #4: Take a Break With deadlines looming and other essays to write, it may be tempting to just rush through after getting feedback and fix everything. But take some time away from your essay, focusing on other college application duties or on other things entirely. Anywhere from a couple days to weeks to months can be good for improving your essay, though do leave yourself time to revise.Taking a break lets your mind forget what you’ve already written, so that when you come back to revise you do so with fresh eyes. This way, you can see holes in your logic or places where your language isn’t as tight as it could be. You’ll never be able to completely shed your attachment to your essay, but spending some time away from it can give you a whole new outlook on your work! #5: Revise Now that you’ve had some time away and you have notes to incorporate, it’s time to revise. Revision can be something you do multiple times, combing through your essay for errors and places to strengthen it, but eventually you are going to have to turn it in. Don’t get caught up in perfection- focus on making your essay the best you can. Check it for spelling, grammar, and punctuation errors to be sure it’s clean and easy to read, and send it off! What's Next? Starting your essay is often the hardest part. If you're unsure where to begin, check out this guide to starting a college essay perfectly, and don't be afraid to just dive right in! A good essay is just one part of a successful Vanderbilt application. If you want to really wow the admissions office, be sure your grades and test scores are up to snuff, too!

Free Essays on Abu Simbel

Abu Simbel The great temples of Abu Simbel are located south of Aswan, in northern Nubia. Pharaoh Ramses II built this monument some say as a gesture of love for his wife Nefertari between 1290 and 1224 B.C., when most of Nubia was under Egyptian rule. The Abu Simbel temples were carved out of a mountain on the west bank of the Nile. There are two: the colossal temple of Ramses, which was dedicated to the Egyptian gods Ra-Horakhty, Amun, and Ptah, and to the deified pharaoh himself. The smaller temple of Nefertari was dedicated to Hathor, the cow-headed Egyptian goddess of love. In the doorway to the main temple are four statues of Ramses, each more than 20 meters high, accompanied by smaller statues of the Queen Mother and Nefertari. Above the doorway stands a figure of the falcon-headed sun-god Ra-Horakhty. Inside, eight statues of Ramses hold up the roof of the Hypostyle Hall; the reliefs on the wall show the pharaoh victorious in various battles. In the next hall, Ramses and Nefertari are shown in front of the gods and the solar barques that will carry them to the underworld. The innermost chamber is the sacred sanctuary, where the gods (including Ramses) sit on their thrones. Every February 22 and October 22 at sunrise, light penetrates the temple and illuminates the faces of these figures....

THE ANALYZING AND INTERPRETATION OF MOVIES - Essay Example Analyzing a movie is especially essential in writing a carefully planned review of it. Furthermore, the pleasure of analyzing a work of an expert and well-known moviemaker can help you take pleasure in a film to a different level on the whole. It’s all a matter of perception. Opportunely or inopportunely, skilled moviemakers do not frequently share the perception of the viewers. Hence, it is important that one appreciates the essence of another’s point of view. There are numerous things about a film which can be analyzed and interpreted to obtain the best idea about what a movie is all about. Movies can be analyzed and interpreted in innumerable ways, and each is acceptable. This essay will discuss what essentially has to be done. Suppose you were asked to write a film analysis for a local newspaper or as university homework. Even if you are a certified movie buff, you do not know anything about doing a film analysis and hence it may appear to be a difficult assignment. Nevertheless, making a movie analysis is not that hard as some people believe. Aside from proficiency in the English language, what a movie analyst needs is some fundamental knowledge about how to construct a film analysis (Rutsky & Geiger, 2005). First, it is important to conduct research work. Prior to watching the movie, it is especially vital to carry out research work (Rutsky & Geiger, 2005). Try to make sense of the movie’s context, such as the underlying plot, the main characters, filmmaker, script writer, and others. Try to determine if the story is a true or original story, sequel of another film, or adaptation of a work of fiction. Movie analyst should also explore earlier works of the actors and the filmmaker (Nelmes, 2003). This aids in identifying the meaning or content of the movie. Second step is watching the movie. In order to make an accurate

War, Revolution and Reconstruction in Europe (1914-1929) Term Paper

War, Revolution and Reconstruction in Europe (1914-1929) - Term Paper Example The protests, revolutions, and the end of World War 1 will also be depicted and a concluding remark will summarize the content of the whole sections of the paper. The Impact of War in Europe The collapse of four empires, Germany, Russia, Austria-Hungary, and Ottoman, was the total impact of fighting on all fronts in Europe. Because of the war, the Treaty of Versailles was laid to settle potential problems and conflicts for the twentieth century. The treaty’s primary purpose was to establish and maintain peace and order, political and economic stability, and to ensure justice for all concerned. Also, the League of Nations was formed to promote global cooperation and attain international peace and order. However, Germany was unsatisfied with the treaty. The whole war was blamed to Germans and they were expected to pay for all the damage they caused. It must be noted that Germany lost a maximum amount of territory and its military declined along with the formation of new independ ent countries (Strachan 228-238). Moreover, because of the various allies that were formed by national leaders in order to protect their land, the whole Europe had been devastated--some of its industrial and agricultural assets. ... This implies that businesses could not sustain its operations that would lead them to stop. Aside from this, employees appealed for wage increase as living cost surged up to three-fourths. Employers were incapable of meeting workforce’ demand for wage increase resulting to a strike. It must be noted that these were the primary reasons that some of the industrial and agricultural businesses compelled to stop on its business operations (Self and Storing 15-36). The Toll of Trench Warfare The toll of trench warfare commenced from September 1914 to March 1918 when Germany and France had nowhere else to go except to use grounds to win the battle. It must be noted that trench warfare was a primitive strategy, but it was in World War 1 that this had caused the highest number of death tool as new defensive weapons, such as barbed wires in the ground and the enhancement of artillery weapons, emerged in the battlefield. Moreover, the trenches built in the war were used by soldiers as th eir hiding place and it had been also used to gain advantage in the warfare as enemies would not detect any trace when opponents attacked through trenches. However, these trenches left troops vulnerable to physical and mental health conditions. These trenches were made because of three reasons: it was easy to make, cheap, and it did not require more troops for defense (Sowder 534-542). Propaganda The â€Å"Rape of Belgium† rooted the propaganda which was made to attract the attention of the powerful country, the United States of America (Manning and Romerstein 324). Prior to this, German invaders burned buildings, sabotaged rail lines, shot offenders, and killed over 6,500 French and

Super Bowl Commercial 2014 Essay Example | Topics and Well Written Essays - 250 words

Super Bowl Commercial 2014 - Essay Example In less than ten seconds, each scene tells a story of a thousand words. There is no mention of the brand name or image of the Microsoft logo throughout the commercial until the very end of the commercial. I believe the commercial brings out the personality of Microsoft. Microsoft strives to invent and develop amazing computer software that caters for not only ordinary people, but people with specific or special needs also. Technology has made life simpler and better. Technology has made people’s dreams a reality and Microsoft is at the forefront of such initiatives. The Super bowl 2014 Apple Inc commercial a competitor of Microsoft known for its IOS operating systems and OS X computer software did not have such a creative well thought through commercial (O’Grady, 2014). The Apple Inc commercial concentrated on their product iPhone and not a broader perspective of what they are all about. The Microsoft commercial was far more superior in terms of quality and was able to market Microsoft as a brand that cares and not a brand that wants to sell only. My favorite spot in the Microsoft commercial was a scene showing a small girl jumping up and down and screaming from seeing her father probably through Skype. It brings out the aspect of how technology builds relationships. The Super bowl Microsoft Commercial 2014 was

In-band or out-of-band SAN appliances Essay Example for Free

In-band or out-of-band SAN appliances Essay Out-of band SAN appliances allow for independent flow of data between servers and storages since it does not function within the data path (InfoWorld, 2001). In addition, execution of management functions by these appliances is independent of application servers, a factor which dictates for having host drives. This has the implication that the positioning of an out-band SAN appliance posses performance concerns in the system (InfoWorld, 2001). Another implication is that increase in the number of server in such a system complicates administration issues. Still, out-of band SAN appliances have its meta-data and control operations separate from the data path. This coupled with the need for having a driver at each host frees the host to engage only in transferring data to and from the storage. Nevertheless, this configuration has the advantage of caching due to the request time delays involved in linking data path information and the appliance for processing. On the other hand, in-band SAN appliances employ a single device for executing all the basic storage management functions namely; data path, control operations, and meta-data management (Kornfeld, 2001). This has the implication that no additional driver software is needed in the host. Also, this enhances scalability of the SAN system. However, this limits the application of in-band SAN appliances in a busy SAN since both meta-data and control operations share the same data path. Despite this, in-band SAN appliances enjoy the privilege of allowing for caching and clustering (InfoWorld, 2001). In addition, being a single device, in-band SAN appliances boast of low cost of implementation and ease of administration (Kornfeld, 2001). Therefore, both in-band and out-of-band SAN appliances have advantages as well as disadvantages. Considerations before choice of a SAN appliance should thus be based on the needs in the particular organization.
