Make and test a hypothesis about the Period of a Physical Pendulum.

You will be given a physical pendulum consisting of a meter stick with holes drilled at various locations, like the 10, 15, 20, 25, 30, ... cm marks.

What factors will control the period of the pendulum? Pick one factor and make a hypothesis about its effect--be as specific as possible (Bad: "factor X will change the period" Better: "Increasing factor X will increase the period." Good: "Increasing factor X will increase the period proportionally.")

Test the hypothesis. You must make measurements carefully enough that you can convincingly tell whether your hypothesis is valid, and this means taking enough accurate data to be able to give an uncertainty.

Report: One brief report per group (probably no more than one page in length) due next class.

  1. It must tell clearly what your hypothesis is,
  2. Describe carefully the procedure you followed,
  3. Give the data
  4. Give a sample calculation of each type of calculation (i.e. show explicitly how you get one average, then just give the other averages),
  5. Make conclusions based on your data.
