EXPERIMENT: Pendulum and the Calculation of g
Questions: A. How did the change in the weight of the bob affect the resulting period and frequency? B. How did the change in amplitude affect the resulting period and frequency? C. How did the change in length of the pendulum affect the period and frequency? D. What would happen if you used very large amplitudes? Check your hypothesis by trial. What amplitude did you use? What is the result? E. Hypothesize about how a magnet placed directly under the center point would affect an iron bob? Try it and find out. Did your trial verify your hypothesis? F. How close was your calculation of the value of g at your location? What might be a few sources for error in your experimental data and calculations? G. What would you expect of a pendulum at a high altitude, for example on a high mountain top? What would your pendulum do under weightless conditions?
