PHY 122 Chapter Notes -Errors And Residuals, Tennis Ball, Stopwatch
Document Summary
Abstract: this experiment was done in order to determine the effects amplitude, length and damping have on the motion of a pendulum. For part one, a tennis ball was attached to varying lengths of string and the period of motion for ten oscillations was found. For part two, the period of ten oscillations for varying amplitudes of the tennis ball pendulum were found. For part three, the motion of a styrofoam ball pendulum was recorded for two minutes. From part one, an experimental value for the acceleration of gravity was found to be 12. 5 +/- . 1 m/s^2. Although that value is much larger than anticipated, the error was largely due to human error in the recording with the stopwatch. For part two, by graphing the amplitude versus the period there was no correlation found as the slope was close to zero (. 003 +/- . 002 sec/deg).
