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'

Your description of the rhythm of the pendulum when tilted 'forward'

Your description of the process used to keep the rhythm steady and the results you observed:

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?

The Pearl Pendulum experiment hasn't yet been assigned. At this point only the TIMER experiment has been assigned from the Assignment 0 Experiments.
