The Simple Pendulum - Essay Example The oscillations were repeated nine times using the same thread, same ball, while varying the length of the thread. The data was collected and analyzed using a graph. The results showed that as the length of the thread was reduced so was the time taken for a complete oscillation. It is widely known that the acceleration gravity g = 9.8 m/s2. (PHY 123 Lab 1 - Error and Uncertainty and the Simple Pendulum, 2010). However, the acceleration gravity may vary and as such the experiment of a simple pendulum can be used to determine the acceleration gravity (L09. Measuring the Acceleration Due to Gravity with a Simple Pendulum). The movement of a fixed object from one point to the opposite side and back to the original point is called an oscillation (Gray, Costanzo, Conaway, Watterson, & Riley, 2005). The period of the oscillation is dependent on the length of the pendulum, the amplitude of the swing and the acceleration due to gravity (PHY 123 Lab 1 - Error and Uncertainty and the Simple Pendulum, 2010). There are a number of factors always ignored that could affect the period of the pendulum-the experimental errors (L09. Measuring the Acceleration Due to Gravity with a Simple Pendulum). The objective of this experiment was to estimate the value of gravitational fo rce (g), based on measurements obtained from a simple pendulum and comparing it to the value of widely accepted value of 9.81ms-2. Moreover, the project aimed at understanding the relationship between different parameters in an oscillating system. The relationship employed in this experiment was: The sphere (golf ball) was connected to a thread to create a pendulum. The length of the thread used for this experiment was 0.79m determined by the measurement tool. A stopwatch was used to set and record the time taken for the oscillations. The pendulum was fixed to a table in order to limit errors and to make the oscillations near perfect. The time was set before the oscillations then measured and recorded

Summary - Essay Example People always perceive that the city life is luxurious and convenient. Even though, this might be true, this is not always the case. For instance, in Aesop’s fable, the country mouse proved to the town mouse that town life is not always reliable as perceived since he could not even have a meal in peace (Carroll 1). This fable was widespread in the Classical era (Carroll 1). Artists such as Horace incorporated the fable in his satires concluding his stories with quotes from Aesop’s fable. Nevertheless, writers from the 12th century, such as Walter of England, contributed most to adapting Aesop’s fable. Aesop was a fabulist credited with numerous fables that are collectively referred to as Aesop’s Fables (Carroll 1). According to historians, Aesop might or might have not written his fables. However, his Romantic writings confirm that he wrote his own works and he should be given credit for writings that seem so contemporary yet
