02 - Galileo's Simple Pendulum

Steps:

• Determine the problem:  How do mass and length affect the period of a simple pendulum?

• Make a hypothesis:  Make a prediction of how you expect each mass and length to change the period.

• Test your hypothesis: Build a simple pendulum (see: you must see the videos:  https://www.youtube.com/watch?v=J-bIXf_xyAg     ) and record the results for each combination below.
• 1. Test the results using the pendulum lab 2.03 simulation located at the PhET site:  https://phet.colorado.edu/sims/pendulum-lab/pendulum-lab_en.html

• Analyze the data for each case:  What were the effects of mass and of length on the period?

• Draw a conclusion:  Report the results from your analysis of the period.

• Comment, in a final paragraph, on your experience with the experiment.  How was it?  What did you learn about the pendulum?  About yourself in the doing of a real experiment?
