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 the

Q1. Outline the historical development of the models of the universe from the time of Aristotle to the time of Newton. Aristotle: Geocentric model of the universe involved a series of 56 concentric spheres to which celestial objects were attached. The Earth was not in motion as the stars showed no measureable parallax. Each planet‚ the Sun‚ and the Moon were in their own sphere and the stars were positioned on a larger sphere surrounding all the others. Ptolemy: Geocentric model of the universe

Introduction: The study of the ballistic pendulum began with Benjamin Robins in the early 1700 ’s. Robins was an English mathematician and writer on ballistics‚ and used this testing apparatus for the evaluation of the strength of gunpowder and the measurement of air resistance (Calvert‚ 2006). At the time of the American Revolution a loyalist named Benjamin Thompson also utilized and expanded the use to the ballistic pendulum. He further evaluated the efficiency of gunpowder. He fired from

.:First experiment:. .Problem: How will the length of a pendulum affect the amount of swings per minute? .Hypothesis: I believe that the length of the pendulum will affect the amount of swings per minute because when the string is shorter in length‚ there would be less friction between the string and the atmosphere‚ causing the string to go faster. .Materials: * String ( should be 70-90 cm long) * Metal washers * Stopwatch * Metric ruler * Stand * Extra washers (You will

Method/Pendulum Exercise Worksheet 1. What is the difference between an observation and an inference? Observations are based on collecting knowledge through our senses. An inference is making an educated guess based on observation. 2. In doing science‚ why are hypotheses either supported or not supported‚ but never proved beyond all doubt? There are many other factors that could be unknown and new data could be found in the future to support or not support a hypothesis. 3. For this pendulum exercise

Pit Bulls are commonly recognized as wild‚ vicious and inherently dangerous animals‚ which is false. “Singling out a particular breed or type of dog has repeatedly been proven to be ineffective because breed alone is not predictive of whether a dog may pose a danger” (The HSUS). How can you look at any given dog or certain breed of dog and know whether it is dangerous‚ just by the way it looks? The answer to that question is‚ you can’t. Look at it this way‚ as a similar scenario‚ how do you know

Misconceptions of Pit Bulls Tori Renfro Few dogs are as renowned and as feared in America as the Pit Bull. The American Pit Bull Terrier is the product of interbreeding between Old English Terrier and English Bulldogs to produce a dog that combined the gameness of the terrier with the strength and athleticism of the bulldog. These dogs were initially bred in England‚ and arrived in the United States with the founders. In the U.S.‚ these dogs were used as catch dogs for semi-wild cattle and hogs

` Pit Bull Stereotyping Has anyone ever come in contact with a pit bull and felt fear that you were going to be attacked or mauled? I bet at least some of you have. I to was one of those people who thought I was going to be attacked‚ But after I owned a few I thought differently. Pit Bulls are banned in some state and counties because the government feels that it is the breed’s aggressive behavior is a threat‚ instead of the owners who made them that way. The pit bull breed has the stereo-type
