HSC PHYSICS 2011 HSC PHYSICS 2011 PENDULUM MOTION BY NATHAN LOCKE Image taken from http://www.practicalphysics.org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In

Symbolism Symbolism is the use of symbols to signify ideas and qualities by giving them symbolic meanings that are different from their literal sense. Symbolism can take different forms. Generally‚ it is an object representing another to give it an entirely different meaning much deeper and more significant. Sometimes‚ however‚ an action‚ an event or a word spoken by someone may have a symbolic value. For instance‚ “smile” is a symbol of friendship. Similarly‚ the action of someone smiling at you

The Swinging Pendulum of Prison Philosophies Brett Spratt Mr. Robert Leonik Contemporary Issues In Criminal Justice November 5‚ 2002 The corrections leg of the criminal justice system is ineffective because the efforts being made to rehabilitate criminals and keep society safe are failing substantially. The reason for the failure of the current correctional system and all correctional systems in the history of American prisons is an imbalance in the goals of criminal sentencing. These goals

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine

Are Pit-Bulls an overly vicious breed or are they just misunderstood by today’s American society? Jessica Williams Strayer University ENG215046VA016 June 04‚ 2011 When you see a Pit bull‚ what is the first thing that goes through your mind? For some‚ it is a sense of fear and for others it is the thought that this breed is misunderstood. Have you ever stopped and thought about if the Pit bull breed is really a vicious breed‚ or are they just misinterpreted due to the reputation that others

An Anonymous author stated‚ “Pit bulls are beauty without vanity‚ strength without insolence‚ courage without ferocity‚ and all the virtues of man without the vices.” (Anonymous) As a Pit bull proprietor‚ I feel that Pit bulls are consistently confounded animals. In fact‚ any animal‚ pit bull or even a Chihuahua can be merciless or delicate. Additionally‚ adore and minding wins out with animals basically as it guarantees with individuals. Furthermore‚ affection is the item that makes a good or repulsive

Dimensional Analysis: Investigation on bifilar suspension Ho Yuk Him (Date of experimentation :20th and 29th October‚ 2010) This paper presents a study on the application of dimensional analysis on the formulation of an equation concerning the periodic time of a rod rotating at an angle about the vertical axis suspended by two strings at each end. We find that period is inversely related to distance between the strings parallel to each other and directly proportional to the both the square root of
