PCS125 Lab – The Simple Pendulum Objective and Background Objective: The Objective of this experiment is to examine the simple harmonic motion and to determine the value of the acceleration due to gravity from the analysis of the period of the simple pendulum. [1] Background: There are three equations that will be used to calculate the period of motion of the simple pendulum. They are the slope of the line of the graph of T² against L‚ and the gravity of the pendulum motion. The period of

Shanise Hawes 04/04/2012 Simple Harmonic Motion Lab Introduction: In this two part lab we sought out to demonstrate simple harmonic motion by observing the behavior of a spring. For the first part we needed to observe the motion or oscillation of a spring in order to find k‚ the spring constant; which is commonly described as how stiff the spring is. Using the equation Fs=-kx or‚ Fs=mg=kx; where Fs is the force of the spring‚ mg represents mass times gravity‚ and kx is the spring constant

Types of Sampling In applications: Probability Sampling: Simple Random Sampling‚ Stratified Random Sampling‚ Multi-Stage Sampling * What is each and how is it done? * How do we decide which to use? * How do we analyze the results differently depending on the type of sampling? Non-probability Sampling: Why don’t we use non-probability sampling schemes? Two reasons: * We can’t use the mathematics of probability to analyze the results. * In general‚ we can’t count on a non-probability

I have had many opportunities to write and I have had both good and bad experiences as a writer. Some of the opportunities I have had recently are writing in my Fundamentals to Writing online class. I also keep a journal of my daily activities and thoughts. I think my most favorite type of writing would have to be free writing by blogging on social networks such as Facebook.. Writing brings out a variety of emotions in me. I feel anxious sometimes when I write and I tend

Simple Harmonic Motion Ethan Albers Case Western Reserve University‚ Department of Physics Cleveland‚ OH 44106 Abstract: In this lab‚ my partner and I observed oscillations that were translational and rotational. The two forms we studied must have a form of a restoring force that is proportional to the displacement of the object from its point of equilibrium. This produces the harmonic motion which this lab wants. At small and big amplitudes we measured/observed the translational oscillation

The Writers’ Voice A writers’ voice can easily change the mood of a story‚ whether it be a happy story or a drastic one. The voice that the writer projects through the selection of words and sentence structure shapes the story and defines its most ponderous points. When Mary Maclane wrote “Me”‚ she used a wide span of vocabulary that shaped the sentences into a more personal piece of writing. When Langston Hughes wrote “Salvation”‚ he used longer sentences to portray the important detail and feeling

The struggle for freedom has existed since the beginning of civilization. When creating a nation‚ leaders must decide who has power and how much power they should have. However‚ finding the balance between an excess of freedom and insufficient freedom is difficult. Two societies for comparison are North Korea and Somalia. North Koreans have little liberty to do as they choose. The government denies human rights and allows citizens to starve‚ while using wealth better spent on its citizens to grow

The gift of magi is a love story of the well-known American writer- O.Henry in which the true love is challenged by the poverty. The love of Della and Jim is apparentlty revealed by the ways they think for each other‚ get ready to sacrifice the most valueable possessions for each other. Especially‚ the devotion of Della is the evidence of intense love she spends for her Jim. Della’s love demonstrates partially Shakespear’s point of view. No matter how poor the living condition is‚ it can not

Simple things in life Have you smiled or said hi to someone today? If not you need to look back and wonder why not. Doing something simple as that makes someone’s day‚ or maybe even making then smile for a second‚ anything will mean something. There are many kinds of kind things you can do for someone‚ you have large actions that you can do for someone or there are smaller actions. No matter what size and kind action can go a long way. The smaller actions are ones that usually mean

Freedom of Change It ’s 2013. Women ’s suffrage has been obtained‚ legal racial segregation has come to an end‚ and labor laws now protect a person ’s livelihood in the workforce. Women‚ non-white citizens‚ and most workers in America‚ have worked very hard to fight for those freedoms and rights. Yet as a country‚ we cannot decide if people of the same sex should be given marriage rights. So will gay couples be given the right of marriage in the years to come? Will their fight for change‚ have
