4. DISCUSSION
 Analyze each of the reasons for errors:
o Timing the oscillations (start and stop):
 Oscillations were noted by starting the pendulum from a set degree. As
we 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. CONCLUSION
This 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
