Finding G Using Simple Pendulum Experiment

Finding G Using Simple Pendulum Experiment Abstract This report shows how to find an approximate of ‘g’ using the simple pendulum experiment. There are many variables we could see into, some of them are displacement, angle, damping, mass of the bob and more. However the most interesting variable is, the length of the swinging pendulum. The relationship between the length and the time for one swing (the period) has been researched for many years, and has allowed the famous physicists like Isaac Newton and Galileo Galilei to get an accurate value for the gravitational acceleration ‘g’. In this report, we will replicate their experiment, and will find an accurate value for ‘g’. Finally it will be compared with the commonly accepted value of 9.806 m/s2 .

Equation 1 shows that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: With T the period in seconds, l the length in metres and g the gravitational acceleration in m/s2. Our raw data should give us a square-root relationship between the period and the length. Furthermore, to find an accurate value for ‘g’, we will also graph T2 versus the length (l) of the pendulum. This way, we will be able to obtain a straight-line graph, with a gradient equal to 4Ï€2g-1 . Equipment and Method For this investigation, limited resources like, clamps, stands, a metre ruler, a stopwatch, a metal ball (bob), and some string were used. The experimental set-up was equal to the diagram, shown in figure 1. In this investigation, the length of the pendulum was varied (our independent variable) to observe a change in the period (our dependent variable). In order to reduce possible random errors in the time measurements, we repeated the measurement of the period three times for each of the ten lengths. We also measured the time for ten successive swings to further reduce the errors. The length of our original pendulum was set at 100 cm and for each of the following measurements, we reduced the length by 10 cm. Figure 1 As stated earlier, it was decided to measure the time for ten complete swings, in order to reduce the random errors. These measurements would be repeated two more times, and in total ten successive lengths were used, starting from one metre, and decreasing by 10 cm for each following measurement. A metre ruler was used to determine the length of the string. One added difficulty in determining the length of the pendulum was the relative big uncertainty in finding the exact length, since the metal bob added less than a centimeter to our string length, measured from the bob’s centre. This resulted in an uncertainty in length that was higher than one would normally expect. The table clamp was used to secure the position of the tripod stand, while the pendulum was swinging. After the required measurements, one experiment was carried out to find the degree of damping in our set-up. Damping always occurs when there is friction, but exactly how significant the degree of damping in our experimental set-up was, remained uncertain. Depending on the degree of damping, it may or may not have a significant effect on our measurements. All measurements were taken under the same conditions, using the same metal bob, the same ruler, in the same room, and at approximately 26 degrees Celsius. Data Collected Table 1 In table 1 the  ±o.46 sec uncertainty in time was obtained by comparing the spread for the different measurements. The time measurement for the 0.50 metre length, had the largest spread ( ±0.4 seconds), and was therefore used as the uncertainty in the time measurement. In table 1 the theoretical uncertainty in the length measurement would be 0.05 cm (a metre ruler was used). However, in the experimental set-up, the two end points (the one tied to the clamp, and the one tied to the metal bob) gave rise to a bigger uncertainty, as the exact end-points could not be precisely determined. We estimated the uncertainty in length to be 0.5 cm, or 0.005 metres. These data in table 1 need to be processed, before we can continue our analysis. First of all, the average of the three trials need to be found, which will reduce our error. Secondly, the time for one swing (or one period) must be found, which will reduce our absolute error, but not our percentage error. It should also be noted, that for all the measurements, a constant, and small, angle of maximum displacement (amplitude) was used. The angle was kept between 5 ° to 7 °, small enough to ignore the friction present in our experimental set-up. Apart from these measurements, one more experiment was done to see how much damping was present in our set-up. It took, on average, between 100 and 150 swings, before the motion had seemed to stop. This showed that there was damping present, but this did not significantly affect the measurement of just ten swings. Table 2 shows the processed data and the uncertainties. While drawing the graph for the data in table 2, the relationship between the variables used is clearly not a linear one. The suggested square-root relationship shows it, and to linearise this curve, it must be interchanged and the axis must be modified. (the graph is shown in Graph 1) Table 3 Based on the theory of Simple Harmonic Motion and equation 1, it should be a linear relationship between T2 and Length. When graphing these two modified variables, the regression line must be linear, passing through point (0,0) and with a gradient equal, or close to 4Ï€2g-1 . Graph 2 Conclusion and Evaluation Graphing the length against T2 clearly shows a linear relationship, in agreement with the theory. The actual line of best fit does not go through (0,0) which suggests a systematic error in our experiment. But when graphing a line of best fit, with the condition it should pass through (0,0), we find a line with a gradient of 4.128 and a correlation coefficient of 0.993, which further suggests a very strong linear correlation between our chosen variables. The value for ‘g’ can be calculated by dividing 4Ï€2 with the gradient of the line of best fit; The uncertainty in this value was found, by taking half the difference of the lowest possible value for ‘g’ and the highest possible value for ‘g’: Comparing our calculated value for the gravitational acceleration ‘g’ with the accepted theoretical value gives us an error of 2.5%, well within the error margins that we calculated. This is a reasonable result, given the equipment and the time constraints that we faced. Looking at our graph, we cannot identify any outliers. However, our data values suggest a line of best fit that does not pass through (0,0). When we do fit a linear regression onto our data values, that passes (0,0), we see that the line does not ‘hit’ all the horizontal error bars (the uncertainty in the length). This may suggest a systematic error in the measurement of the length of our pendulum. Further Improvements To reduce the systematic error in the length measurements, one should take accurate measurements of the diameter of the metal bob used. In this experiment, it looks as if we systematically used a length for the pendulum that was too short. If 1 cm was added to our data, we would get a value for ‘g’ that is equal to the theoretical value of 9.806 m/s2 . The theoretical value used, is the average value for ‘g’ on Earth, and may be slightly different from the one that was measured. Instead of three measurements, taking five measurements would be better, as it would not take too much extra time, and this would further reduce our uncertainty in the measurement of the period of swing. Alternatively, measuring the time for 20 swings, instead of 10 swings, would also reduce the uncertainty in time. Lastly, a photogate could be used in the future, to measure the period with higher precision. A nice extension to this experiment would be the use of different metal bobs, of different diameter and/or mass. This would allow us to calculate the effect of air resistance on this experiment.

How Does Ethical Dilemma Occur - Free Essay Example

Sample details Pages: 6 Words: 1733 Downloads: 3 Date added: 2019/05/17 Category Society Essay Level High school Tags: Ethical Dilemma Essay Did you like this example? According to Murray (2017), an ethical dilemma occurs when obligations, principles, rights, values, and beliefs are in conflict (p. 73). They arise when the only choices available are undesirable (Murray, 2017, p. 73). With outcomes of patient demise with either choice, physician assisted suicide (PAS) clearly meets the criteria of an ethical dilemma. History Euthanasia has a long history around the world as well as the United States. The first set of ethical standards that were established to guide the practice of medicine was in 400 BC at the School of Hippocrates. These ethical standards are found in what is known as the Hippocratic Oath. This oath, held by physicians, guides them to treat the patient to the best of their ability while maintaining the privacy of the patient and promising to teach younger generations the knowledge of medicine. Don’t waste time! Our writers will create an original "How Does Ethical Dilemma Occur?" essay for you Create order In the 1900s, the right to death was a topic of discussion throughout Europe. In 1920, in Germany, home of the most scientifically advanced medical community in Europe, a booklet titled Permitting the Destruction of Unworthy Life was published (Vizcarrondo, 2017, p. 1). This booklet brought to light the ideation that it should be legal to kill people that were deemed unworthy of living. In Germany, after this booklet was published, physicians and nurses legally practiced the organized killing of human beings. PAS has now made its way to the United States (U.S.). As of 2017, five states have passed a statute governing PAS. In chronological order, they are: Oregon (1994), Washington (2008), Vermont (2013), California (2015), and Colorado (2016) (Sullivan, 2018, p. 50). There are 17 other states who are currently considering the passage of death with dignity laws. There are requirements for PAS laws. The requirements include that eligible patients must be 18 years of age or older and have a terminal illness, with a death prognosis of six months or less. In regards to the physician, they must have an active license in the state and must inform the patient of all possible options. The last requirement of the PAS laws deals with timing. There must be an Initial verbal request, followed by a 15-day waiting period. There must then be a second verbal request to the physician, followed by a written request. Finally, there must be a 48-hour waiting period before the patient can pick up the medications from a participating pharmacy (Sullivan, 2018, p. 50). These requirements are important to the PAS laws because they establish criteria for who may receive and who may administer this procedure. With such a highly debated ethical topic such as PAS, clear guidelines are necessary to help prevent misuse of this procedure. Ethical Principles In nursing there are eight ethical principles that nurses must practice including autonomy, beneficence, nonmaleficence, justice, fidelity, veracity, privacy, and confidentiality (Murray, 2017). So, how does a nurse juggle their ethical responsibilities and their own personal beliefs when it comes to PAS? The ethical principles which relate most to PAS are autonomy, beneficence, and nonmaleficence. Each of these principles have specific factors which can lead to significant moral distress in nurses and can have weighing effects on the patients as well as the patients family and friends. Autonomy Autonomy is defined as self-governance, in that an individual is free to make choices about what can be done to his or her body (Murray, 2017, p. 65). This ethical principle is one which can be very challenging in the context of PAS. From a nursing standpoint the nurse should always advocate for their patient as far as what the patient wants and what is best for that patient. In situations such as this, the nurse may be experiencing significant moral distress related to his or her own beliefs regarding PAS. Furthermore, as a persons death approaches, dilemmas around quality of life and wanting to proactively end life can be complicated and distressing for all concerned (Costello, 2014, p. 55). Therefore you cannot just look at the nurses feelings of the situation, you must also consider the patient as well as their friends and family. The patient may want to end their life, but they also may want to be there to comfort their friends and family throughout the end of their life. On the other hand, the patients family and friends may wish for the patients suffering to end but are not prepared or ready for their loved one to die. In reality, the patient should have full autonomy over choices regarding their care; however, in most states in the U.S. it is illegal to provide PAS. This means that patients typically do not have this option whether it is within their wishes for end-of-life care or not, which ultimately limits their autonomy. Beneficence Beneficence is a core principle of patient advocacy and refers to any action intended to benefit another (Murray, 2017, p. 66). When referring to beneficence arguments can be made regarding PAS as to whether or not it supports this ethical principle. According to Kiger (2015), if the patient has no hope of recovery and might spend further weeks or months in discomfort, living a life devoid of value, ending that life would be an act of kindness, which would essentially an act of beneficence (p. 4). Another point of view would be that if the patient wishes to participate in PAS, but they have a chance of recovery or their condition is not one with debilitating factors that may significantly decrease their quality of life, then providing PAS would defy the ethical principle of beneficence. Nonmaleficence Nonmaleficence is the moral obligation to do no harm or injury to another person (Murray, 2017, p. 66). If a patient is constantly in significant pain, has a remarkably decreased quality of life, and has no hope of recovery then ending that life would prevent needless pain and suffering (Kiger, 2015, p. 4). In other words, it would be an act of nonmaleficence and would be considered ethical. From another perspective, the patient may have a chance of recovery with the hope of decreasing their pain and increasing their quality of life. In this scenario it would be considered a breach of nonmaleficence to allow or advocate for PAS. In doing so the nurse is advocating for the patient to die without good reason; therefore, causing harm to the patient. Ethical Platform When a nurse decides whether or not to take an ethical stand for or against PAS many are set in their beliefs and firm in where they stand. Through this study, the platform reached was divided evenly down the middle, which is reflected in the research and in surveys reviewed. Each opinion was formed and framed based on individual experiences and beliefs. When faced with an ethical dilemma such as PAS, each nurse should reflect upon their own beliefs and know where they stand morally and ethically. There is no specific right or wrong, and nurses may differ in their opinion with each situation they encounter. The American Nursing Association (ANA) Code of Ethics was developed more than 65 years ago, with many provisions being made over time, yet the principles remain the same. Ethical code 1.4 Right to Self-Determination is described as, Nurses should provide interventions to relieve pain and other symptoms in the dying patient consistent with palliative care practice standards and may not act with the sole intent to end life (Code of Ethics, 2015, p. 3). Respecting patient autonomy is to respect a patients right to self-determination (Murray, 2017). Patients can make choices to what extent of care or life sustaining treatment they want to receive, and as previously stated there are states in which a patient with a terminal illness can decide to end their life. PAS is illegal in the majority of our country, and the ANA states that, nurses are strictly prohibited from participating in PAS (Pedersen Tariman, 2017, p. 25). Where is the line drawn in deciding how far a nurse can go to respec t a patients autonomy? Concerning beneficence and adhering to the duty to do good nurses must uphold and constantly advocate for a patients needs and wishes (Murray, 2017, p. 65). Nurses working in areas such as hospice, critical care, or oncology are often faced with patients who are suffering from unrelieved pain, and many request help with ending their suffering. This leaves nurses in an ethical predicament; does one allow their patient with stage four terminal esophageal cancer who has requested death with dignity to suffer from pain and starvation or does the nurse empower the patient by advocating for their request. To determine a nursing standpoint on such dilemmas, 539 nurses in Nevada were given an end-of-life survey. Out of those nurses surveyed, 53% expressed support of PAS, including death with dignity (Pedersen Tariman, 2017, p. 35). The ANA stands against PAS, yet the nurse may administer pain medication that may potentially hasten the patients death based on the principle of double effect, which is defined as the justification of claims that a single act having two unforeseen effects, one good and one harmful, such as death, is not always morally prohibited if the harmful effect is not intended (Pedersen Tariman, 2017, p. 26). This seemingly contradicts the ethical principle of nonmaleficence. Even though a harmful effect was not intended, how can the principle of double effect be ethically justified? Yet, nurses who participate in PAS can still face criticism. In San Francisco, out of 24 different health care facilities serving AIDS patients, 54% supported PAS for its ability to relieve suffering (Pedersen Tariman, 2017, p. 35). While many nurses are supportive of PAS for their strong beliefs in patients dignity and autonomy those who are unsupportive cite that personal ethics, religion, and the potential fo r abuse of PAS defines their moral disapproval of PAS (Pedersen Tariman, 2017, p. 36). Conclusion When questions of moral rightness or wrongness underlie a nurses decision making and care of patients in a beneficent manner, ethical issues will arise (Stanhope Lancaster, 2017, p. 51). These ethical issues grow into dilemmas when there are justifiable reasons for either option (Stanhope Lancaster, 2017, p. 51). It is clear that there are arguments for and against PAS, with each side justifiable by basic principles of ethics. While at this time the ANA Code of Ethics prevents nurses from participating in PAS, there may come a time when nurses will have to choose for themselves. It is key that each nurse examines their own personal beliefs and feelings prior to facing such a decision. If necessary, they need to be prepared to step aside and let another nurse provide care during PAS if they cannot resolve doing so with their own beliefs.

The Science Fiction Film Genre Essay - 1691 Words

The science-fiction film genre serves as an excellent medium for examining shifting power structures, social paranoia and Cold War politics during the 1950s. A number of films released during this period, including: Invasion of the Body Snatchers (1956), The Day the Earth Stood Still (1951), Them (1954) and Attack of the 50ft Woman (1958), are particularly symptomatic of the social and political atmosphere of the time. These films navigate not only narrative based issues such as the threat of aliens and science experiments gone wrong; but also wider issues of the time, such as the Cold War, changes in the US film industry, urbanisation, politics, the growing power of women and most significantly, social concern about nuclear energy. Before analysing individual science-fiction films from the 1950s, it is important to gain a clear understanding of the social, cultural and political background against which these films were set. Paranoia is a term frequently used to describe an acute, anxiety dominated medical condition (Paranoia, 2009), however in the context of 1950’s America, this term can be used more accurately to describe the general, delusionary mood of the nation. The first important event that influenced a paranoiac filmmaking atmosphere was the Cold War. As opposed to the ‘hot war’ (WWII) that involved active military hostilities, the Cold War was based on heightened tension and suspicions between Western Bloc (USA) powers and Eastern Bloc (Soviet Union) powers (TheShow MoreRelatedThe Science Fiction Film Genre Essay1683 Words   |  7 PagesScience Fiction Films The science fiction film genre has been around almost as long as movies have, but like the cinema it is still a fairly young art form.
