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

Good Luck Symbols Many of us believe in carrying good luck symbols or charms with us‚ so that we are successful in our task. The article enlists some of the popular symbols that are believed to bring good luck. Being lucky or unlucky is merely a mind game and the definition of luck may change from person to person. It is just a belief whether you consider a particular incidence to be a good fortune or bad. A good luck symbol is nothing but an event or object that is believed to bring good luck

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

Imagine this world without Pit Bulls‚ Pit Bulls do not always have to be vicious‚ any dog can be vicious but people only care about if it is a Pit Bull or a dog that looks like a Pit Bull. Now should Pit Bulls be allowed as pets‚ YES! They are great family pets. First‚ we should be allowed to have Pit Bulls as pets. Pit Bulls as pets. Pit Bulls were a respected breed‚ Pit Bulls were brought by Irish immigrants. They were specified as working dogs‚ otherwise they were hunters and guardians and

This symbol reminds those handling the package to keep out of the rain and not to store it in damp conditions. It is normally found on card based packages which would be damaged if placed in contact with water. The broken wine glass suggests that the product inside the packaging could be easily damaged if dropped or handled without care and attention. The contents are fragile! The two hands holding or protecting the package is another reminder that the contents should be handled with care

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
