Free Fall Methods Investigation Aim I am going to use three different methods in which I will find the value of gravity (g). Then I am going to compare all three methods to see which is the best. The three experiments will be - Pendulum - Spring - Electronic timer Background Research Free fall Is motion with no acceleration other than that provided by gravity‚ and no deceleration other than that caused by the aerodynamic drag of the object (hence the term also applies for moving

simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the masses‚ support for each pendulum‚ a stopwatch‚ and a measuring tool such as

Essential Theory In order to gain understanding on the workings of these phenomena‚ I will be starting with the mathematical expressions for both a single pendulum and the coupled pendulum system‚ in particular the equation of motion: Where J is the moment of inertia (=)‚ is the length of the pendula‚ and is the length down the pendulum of the coupling device. If we then use the identity‚ and assume that‚ for small angles‚ we can simplify this equation to: As the coupled pendula system exhibit

One conscientious student had breezed through the questions until he read the last one: "What is the first name of the woman who cleans at your floor in the school?" Surely this was some kind of joke. He had seen the cleaner several times

Galileo Galilei Galileo was born in Pisa (then part of the Duchy of Florence)‚ Italy‚ the first of six children of Vincenzo Galilei‚ a famous lutenist‚ composer‚ and music theorist; and Giulia Ammannati. Galileo became an accomplished lutenist himself and would have learned early from his father a healthy scepticism for established authority‚[15] the value of well-measured or quantified experimentation‚ an appreciation for a periodic or musical measure of time or rhythm‚ as well as the illuminative

PHYS 221 Experiment M10 Harmonic Motion of a simple Pendulum Jacob LaMarre Group members: Josh‚ Courtney‚ Ashley Abstract: Determine the acceleration due to gravity using a pendulum. Introduction: A simple pendulum consists of a mass suspended by a length of string. When set Oscillating‚ the mass will have a period “T” given by the following equation. This equation shows the only variables that affect the rate at which the pendulum swings is the length “l” that is measured to the center
