Students analyze data from a swinging pendulum to determine the formula for the period of a pendulum using regression and dimensional analysis.
Students study the relationship between a pendulum's length and its period.
First, they examine a graph of pendulum position vs. time and determine the pendulum's period.
Next, they plot period vs. pendulum lengths for a number of pendulums.
Finally, students determine the equation relating pendulum length to pendulum period.
