Your 'pearl pendulum' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Your general comment, if any: **
** Your description of the rhythm of the pendulum when tilted 'back' **
The sounds get closer and become quieter as they speed up.
** Your description of the rhythm of the pendulum when tilted 'forward' **
The sounds become further apart and quieter as the pendulum swings.
** Your description of the process used to keep the rhythm steady and the results you observed: **
Doesn't work. No pearl included in kit and can't find anything that will work.
** Your description of what happened on the tilted surface (textbook and domino), rotating the system 45 degrees at a time: **
** Your description of how you oriented the bracket on the tilted surface to obtain a steady rhythm: **
** Your report of 8 time intervals between release and the second 'hit': **
** Your report of 4 trials timing alternate hits starting with the second 'hit': **
** The length of your pendulum in cm (you might have reported length in mm; the request in your instructions might have been ambiguous): **
** Your time intervals for alternate 'hits', starting from release until the pendulum stops swinging: **
** Your description of the pendulum's motion from release to the 2d hit: **
** Your description of the pendulum's motion from the 2d hit to 4th hit: **
** Your description of the difference in the pendulum's motion from release to the 2d 'hit', compared to the motion from the 2d 'hit' to the 4th hit: **
** Your description of the difference in the pendulum's motion from the 2d to the 4th 'hit' compared to the motion from the 4th to 6th hit: **
** Your conjecture as to why a clear difference occurs in some intervals vs. others: **
** What evidence is there that subsequent intervals increase, decrease or remain the same: **
** What evidence is there that the time between 'hits' is independent of the amplitude of the swing? **
