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

The Devils Highway Valdivia 1 Have you ever wonder why they built borders? Or who built them? Or who prevents and controls illegals from crossing‚ and what they do to accomplish them from crossing? In the book‚ The Devils Highway‚ by Luis Alberto Urrea defines the effects the desert has to offer for the immigrant’s entrance. The Devils High Way is a measureless desert past Mexico and Sonora

In William Shakespeare’s "Othello"‚ the character Iago is‚ at least in my point of view‚ the main and most interesting character. Iago is in virtually every scene in the play‚ and has his hands in almost all doings within the play. Iago is truly one of the greatest villans in literature. Iago is viewed by all in the play‚ with the possible exception of his wife‚ as an honest and trust worthy man‚ which could not be farther from the truth. Iago plays all the characters in the play like puppets. He

CENTRIPETAL FORCE ON A PENDULUM OBJECTIVE To measure centripetal force exerted on a pendulum using the force sensor bob and in so doing compare this value determined by force calculations based on the height of the pendulum. THEORY Newton’s laws of motion are the basis for this experiment. Newton’s first law of motion states that a body in motion will remain in motion unless acted upon by an external force. Newton’s second law of motion states that the rate of momentum of a body is dependent on

the simple pendulum 2.0 Objectives The purpose of the experiment is to investigate the time taken on the greatest possible precision of period of simple pendulum and the value of g‚ acceleration due to gravity and two different periods of both big and small simple pendulum’s oscillations. 3.0 Summary of Result The results of the experiment have proven the acceleration due to gravity and the precision of period of simple pendulum. Besides that‚ the length of the pendulum did influence

Was Tom Powers a villain or a hero? Well it depends on who you might ask. From the outside point of view‚ you might see Tom as someone who is not so nice morally. He is rude to others‚ he grew up a thief‚ and did not seem like he was very pleasant. But if you were to ask this question to his best friend‚ he would probably say he really is a nice guy‚ just different‚ and is trying to make a living during the prohibition era. Tom also cares about his family. He does not get along with his brother very

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors. Materials Lab stand Protractor Cardboard Fishing line Stopwatch Weights Hook for weights Tape Ruler Weighing scale Logger Pro Variables Independent Angle of release Dependent Period Length

Pendulum Problems ACTIVITY 1: Copy and paste the example problem and the steps‚ so that the steps are in the correct order into a new Word document and upload it to Moodle. Example Problem 1: A hypnotist swings her watch from 20.0cm chain in front of a subject’s eyes. What is the period of the swing of the watch. Thus‚ we see that the pendulum used by the hypnotist has a period of 0.898s. | Before we can use this formula‚ however‚ we must ensure all our variables are in the correct units.
