I. INTRODUCTION The purpose of this lab was to make observations, and interpretations, of simple harmonic motion of a mass hanging from a spring. In order to achieve this we not only measured the position of the mass as a function of time, but also compared the motion of the mass to a mathematical model. We were finally able to determine, through mathematical calculations the amplitude, period and phase constant of the observed simple harmonic motion. A video located inside of the Logger Pro software contained the mass loaded spring in movement for us to analyze. With the aide of this Logger Pro software we were able to not only make the aforementioned calculations, but were also able to translate them into Position v. Time graphs for quick analysis. II. PRELIMINARY QUESTIONS In this lab, a list of ‘preliminary’ graph sketches were requested to be drawn. The first type of graph requested was the Position v. Time graph (the same type of graph that was created from the lab video). Secondly, is the Velocity vs. Time graph. These two graphs reflect my personal prediction(s) on what the resulting Logger Pro graph will look like, (a comparison with the Logger Pro graph will a bit later):
III. THEORY On the Position v. Time graphs, the X-axis represents the amount of time passed in measurements of seconds. The Y-axis represents the position of the subject matter in meters. I predicted in this case that the quantity graphed would lie within the first quadrant since it is not
