1.When measuring the pendulum period, should the interface measure the time between twoadjacent blocks of the Photogate? Or is some other measurement logic used? Why?2.Plot a graph of the pendulum period,T,vs. amplitude in degrees using LabQuest, LoggerPro, or graph paper. Scale each axis from the origin (0,0). According to your data, does theperiod depend on amplitude? Explain.3.Plot a graph of the pendulum period,T,vs. length,, using LabQuest, LoggerPro, or graphpaper. Scale each axis from the origin (0,0). Does the period appear to depend on length?4.Plot a graph of the pendulum period,T,vs. mass using LabQuest, LoggerPro, or graphpaper. Scale each axis from the origin (0,0). Does the period appear to depend on mass? Doyou have enough data to answer this conclusively?5.To examine more carefully how the period,T, depends on the pendulum length,, create thefollowing two additional graphs of the same data:T2vs.andTvs.2. Of the three period-length graphs, which is closest to a direct proportion; that is, which plot is most nearly astraight line that goes through the origin?6.Using Newton’s laws, we could show that for a simple pendulum the period,T, is related tothe length,, and free-fall accelerationgbygT2, orTg224 Does one of your graphs support this relationship? Explain.Hint: Can the term inparentheses be treated as a constant of proportionality?EXTENSIONS1. From your graph ofT2vs., determine a value forg.2.Given what you observed in this experiment, write a set of rules for constructing a pendulumclock that is reliable under a variety of temperatures.

Pendulum PeriodsPhysics with Vernier11 - 53.Try a larger range of amplitudes than you used in Part I. If you did not see a change in periodwith amplitude before, you should now. Check a college physics textbook for an expressionfor the period of a pendulum at large amplitudes and compare to your own data.
