Physics PENDULUM INVESTIGATION Aim of the investigation The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts‚ to the opposite end‚ and back again). This will give me an insight into what will effect the time of the swinging of the pendulum‚ be it weight‚ string length‚ the angle‚ or the swinging point. Planning my investigation

| The Ballistic Pendulum | Determining the initial speed of a projectile | | | | | THE BALLISTIC PENDULUM ABSTRACT The experiment was carried out to determine the initial speed of a projectile: i) by means of a ballistic pendulum. ii) by measurements of the range and vertical distance of fall during its flight. The initial speed for the ballistic pendulum was found to be 5.0551±0.0008m/s and the initial speed for the pendulum was found to be 4.72±0.02 m/s. INTRODUCTION:

The Ballistic Pendulum Crime Lab Physics You are a criminologist‚ and have been given a gun which has been used in the commission of a crime. Both prosecution and defense claim that "muzzle velocity" (speed of the bullet as it leaves the gun) is crucial to the case. Your job...FIND IT! Shown below is a diagram representing a "ballistic pendulum." The bullet is fired into the block‚ the bullet-block combination rises by a height h as shown‚ a little physics is applied‚ and ...voila!...there

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Pendula A pendulum consists of an arm of low mass with a bob‚ which has a higher mass‚ on the end. The top of the arm is pivoted so that the pendulum can swing. A pendulum will continue to swing back and forth indefinately‚ until it is stopped by air friction and friction within the pivot. When the angle‚ á‚ between the stationary line of the pendulum (the line towards which the movement tends) and the line of maximum amplitude of the pendulum is quite small‚ then the time period of the pendulum can be

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction‚ and we have instinctively learned to take advantage of friction‚ or the lack of friction‚ since our childhood. Simple devices that rely on friction are everywhere around us. This workshop will help you see and appreciate the role of friction. As we study friction‚ lets also think about the differences between what scientists do and what engineers do. In

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze
