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:
I purchased the Lab kit at the bookstore and all I recieved was a straw, rubber bands, paper clips and the required Cd's. On the Lab Kit list it shows all of the magnets, straps, a knife, marbles and I did not recieve any of this. Have they gave me a wrong Lab Kit or are these things just missing? It was a very small package for $33. Is there an alternate assignment I should do?
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?
That wasn't the lab kit you purchased. That was the CD package with initial materials.
The price they charged was for the Standard Kit. Tags must have been switched.
I'll talk to them tomorrow and see how they want to go about correcting the error. Hang on to the lab kit and your receipt.
I'll also be sending out an email about this.
