Aswe counted each oscillation, a stopwatch was used to keep time. Starting the pendulum and stopwatch may have added some milliseconds between each start. Compare the spring constant that you obtain in Part I and that in Part III to see how close they are. Give reasons for the discrepancy. 5.CONCLUSIONThis experiment was completed in order for our group to understand how the simple harmonic motion is created and measured. The data was determined to be accurate once compared to other results. This lab had many forms of error. In simple harmonic motion, the
