Experiment The equation of motion for Pendulums.
1) What are the most significant sources of experimental uncertainty? Be specific.
2) How did you ensure that the initial angle from which the bob was released was less than 15 degrees?
3) Which of the following variables affects the time it takes a pendulum to complete one cycle: mass, length, amplitude?
4) For each of those variables indicated in #3, describe how your data support your answer.
5) In this lab, you learned that dissimilar in measurement do not imply a important physical relationship.
Apply this lesson to your data and explain a case in this lab where the data does not support the conclusion that the independent variable affects the period of a pendulum.
