Soccer Ball Lab Essay Example for Free

Soccer Ball Lab Essay I. INTRODUCTION Speed, distance, time, and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed, distance, time, and acceleration. Distance and time are two formulas that are used to determine speed and time. For example, distance equals speed multiplied with time given, time equals distance divided by speed, and speed is equals distance divided time. Speed and time are required to determine acceleration. ( This is how they are an interdependent formula. ) These complex formulas will benefit you in situations , where as you are trying to find the missing equation value dealing with motion data. For example, in many situations, the problem gives information with only the values of time and distance. You are trying to solve for the speed in the given problem, so in order to determine the speed, you’d have to taken the given information and divide the time by distance. In other situations, you are trying to solve for acceleration, which only initial velocity, time, and acceleration are given. You would have to interrelate the given values and take the initial velocity and add it to the acceleration, multiplied by time, then your data and equations sum up to the final velocity. These formulas and equations, in particular, acceleration and speed, are related to Newton’s first law of motion. This is also known as inertia, inertia is the resistance of any physical object to a change in its state of motion and rest, or the ability of an object to resist any change in its motion. Objects at rest will remain at rest if both acceleration and speed are equal to zero . Newton’s first law of motion states â€Å"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.† An unbalanced force is when 2 forces are not equal they work against each other. It acts upon an object, either opposite, or beside it. Depending on the situation, an unbalanced force can make an object either decelerate or accelerate. Friction is a common force that forces  objects to decelerate. Now, acceleration is compatible with this situation because when an object is traveling at a certain speed, eventually it will slow down and stop. Inertia works with the situation, because inertia is a property of mass, meaning the larger the mass, the more inertia there is. Mass is a measurement of the amount of matter an object contains, therefore the larger the mass, the more the object resists its change of its state of motion and deceleration. All of these are interdependent and interrelated resulting in all the solutions to these complex equations dealing with motion and time. II.PURPOSE AND HYPOTHESIS The purpose of this lab is to determine whether a soccer ball will accelerate, decelerate, or travel at a constant speed when kicked from a certain distance to another. If a soccer ball is kicked from a certain place to another, while being timed, then the soccer ball will decelerate .This is because the incredible force of friction will work against the force moving the ball. The unbalanced force will cause the ball to decelerate and eventually stop. III.MATERIALS 1. (1) Stop watch 2. (2) Soccer Ball 3. (1) Chalk/ Marker- IVPROCEDURE 1. Position yourself at a designated, and marked place. These must be measured in units, in order to get an accurate description. 2. Stand in your designated area, until the soccer ball reaches it. 3. Have the ball be kicked.  4. When the traveling soccer ball reaches you, stop and record your time. 5. Record the time showed on the stopwatch on a piece of paper This can be redone multiple of times. V.OBSERVATIONSobser * QUALITATIVE: The group walked to the measuring area ( A parking lot ), where stations were set up. A straight line, that measured 10 meters was marked across with a  piece of chalk. The soccer ball was very soft and deflated to have a more accurate observation. The soccer ball traveled on ground until stopped by a person. * QUANTITATIVE: Distance (m/s)| Time (Seconds)| Instan. Speed (m/s)| Acceleration (m/s ²)| 2| .47| 4.25| -4.7| 4| .93| 4.30| -0.62| 6| 1.5| 4| 1.57| 8| 1.8| 4.44| 2.21| 10| 2.49| 4.01| 2.22| Graph, representing distance vs. time. VI.ANALYSIS AND CONCLUSION When the soccer ball was kicked, and measured, it traveled and eventually decelerated. Now, the ball decelerated, but not at a constant rate. It depended on various things in order to have taken the ball to either decelerate faster, or for the ball to have travel faster. But, in this case, the soccer ball accelerated very slightly on halfway to the 8 meter mark. This was due to friction and an unbalanced force, that took control of the 14 ounce soccer ball, and made it decelerate. The question, is why the soccer ball went at the speed, and not at a faster speed. Well, one person was chosen to kick the ball. The person, if they wanted to, could have either kicked the ball softly, or put more pressure into kicked it. If more people were selected to kick the soccer ball, the amount of force exerted on the ball might have been different. The factors that determine the speed the ball are the amount of force initially exerted on the ball and the unbalanced force. In this case, it was frict ion that acted upon the ball. VII.DISCUSSION Although, the group remained and recorded many accurate results, there were some complications. When conducting the lab, some people at other designated spots pressed their stop watches too early, resulting in different results. Another error that might have occurred, is that too much force was exerted on the soccer ball, when kicked. This could have resulted  in the soccer ball traveling at a faster rate. Either that that, the most observations and results were accurate.

The Paradox Of Community Essay -- essays research papers

The Paradox of Community   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"One can see that insiders are caught in the paradox of community: The same cultural vocabulary that undermines community is simultaneously that community's idiom of self-affirmation† (Greenhouse, et al. 175). In Law and Community, David M. Engel explores how ordinary people in a small, rural, Illinois town perceive the law, courts, litigants, and community. By analyzing the legal practices and relations in Sander County, it is evident that law and the courts play a central role in the processes of making and unmaking communities. Furthermore, this study illustrates how such manifestations, reflections of the â€Å"insider's† ideology, fail to live up to the promises for â€Å" law† in our society.   Ã‚  Ã‚  Ã‚  Ã‚  In the 1970s, Sander County was undergoing great social and economic changes. Agriculture, a central part of life for most residents, became more mechanized and a few large manufacturing plants opened, bringing in â€Å"quite a number of a certain element† Sander County had â€Å"never had before† (29). Long- time residents, worried about change, express what they believe to be â€Å"the new role of laws and the courts in the local and national societyâ€Å" (1).   Ã‚  Ã‚  Ã‚  Ã‚  Though personal injury litigation rates are lower in Sander County than other major types of litigation, a norm of aversion towards this legal discourse is evident throughout the majority of the community. Those who enforce personal injury claims are viewed by fellow residents as greedy, selfish, and â€Å"quick to sue.† Litigation is portrayed as weakening the collective values personified in the law as a means of turning the law against the community to make an â€Å"easy buck† (144). Even highly respected members of the community are criticized for making personal injury claims. For example, a minister filed a suit after slipping and falling at a school. A local observer commented by saying there are â€Å"a lot of people who are resentful for it, because...he chose to sue† (28). The long-time residents of Sander County were experiencing a prevalent sense of a collapse in the conventional dependencies and exchanges that had typified life in Sander County. Understandings of personal injury claims are largely shaped by these societal transformations as the local populace encounters them and also by the notion that traditional relati... ...ty (Carter 11). The irony lies in the fact that the power of the insiders as a whole disempowers the individual, whether the individual is an insider or an outsider. Every member of Sander County is rather powerless before the law; the efforts to keep the town safe from change paradoxically caused a lack of trust in the legal process. This lack of trust contributes to the chaos of community that already existed in Sander County.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Law is a language by which we constantly reconstruct our communities† (Carter viii). Instead of constructing community through just legal discourse, Sander County destructed what it had left of a community in a desperate act of warding of that which it did not understand (or did not want to understand). Law in practice, in Sander County, does not produce justice; it produces inequality. This prevalent inequality, or difference, is a â€Å"justification of litigation by ‘insiders' in defense of their community† (Greenhouse, et al. 175). They fail to see that their myth of community is challenging â€Å"community.† Disempowerment and inequality will not generate trust. Furthermore, of what use, or longevity, is a community without trust?

Opposites Attract

Opposites attract, similar to how magnets are drawn to each other. This tragic love story sheds light on Romeo and Juliet, a pair of star-crossed lovers. The play Romeo and Juliet, written by William Shakespeare, features a love story between the two main characters, Romeo and Juliet and takes place in Verona, Italy. There are two rival families, the Capulets and the Montagues, and Juliet and Romeo are the â€Å"star-crossed lovers† from the two opposing families. In Act II Scene II, Romeo is talking to Juliet on the balcony immediately after they meet.Here, Shakespeare reveals Romeo’s and Juliet’s personalities in the scene. Shakespeare reveals a passionate and impulsive side to Romeo, while on the other hand, reveals a hesitant and cautious side to Juliet. Shakespeare reveals that Romeo has a passionate, as well as impulsive love for Juliet. In the balcony scene he says to Juliet, â€Å"My life were better ended by their hate, than death prorogued, wanting of thy love. †(82) This suggests that Romeo is saying that he would choose death over Juliet not loving him, and reveals his fervent love for Juliet.Also, he boldly states, â€Å"Therefore thy kinsmen are no stop to me. †(72) He declares this because he is so deeply in love with her. He has the courage to say this even when he knows that Juliet’s relatives want to kill him because he is a Montague. Romeo’s impulsive behavior is suggested when he asks, â€Å"Th’ exchange of thy love’s faithful vow for mine†(134). Even though Romeo had just met Juliet that night, he proposes that they get married, which reveals that he is impetuous. Romeo is characterized as passionate but impulsive, which leads him rushing into decisions, and ultimately his death.Juliet is shown to be hesitant and cautious because is mature beyond her age. She is cautious about Romeo’s love for her, almost skeptical of it, because she says to him, â€Å"And if thou dost love, pronounce it faithfully† (99). This shows that she wants to be reassured that he truly loves her. When Romeo proposes for them to marry, she responds â€Å"It is too rash, too unadvised, too sudden† (125) which shows that Juliet thinks that they should be careful, because she believes their love is developing too quickly.She then compares their love to what it could be, â€Å"Too like the lightning, which doth cease to be† which means that like lightning, their love can disappear as fast as it appeared. She is worried that this will happen to them as well. Her cautious and hesitant behavior balances out Romeo’s character and actions. Shakespeare suggests that Romeo and Juliet are very different in character. Romeo is quick to act, while Juliet takes her time and thinks of the possible outcomes. Their personalities create a perfect balance.Although they complete each others’ personalities, their young and sudden love is like the always ch anging and tumultuous ocean. The two lovers should not rush into their love because their love for each other, as Juliet says â€Å"Follow thee my lord throughout the world†, foreshadows that Juliet will ultimately follow Romeo into death because of their love. Love holds the power to make people do extraordinary things but sometimes may lead to irreversible consequences, such as death.
