Getting Started: Pendulum Lengths and Periods

Getting Started is a fast-paced introduction. Read the chapter for details.
A group of students is attempting to determine the mathematical relationship between the length of
a pendulum and its period (one complete swing of a pendulum). The group makes a simple
pendulum from string and washers and then suspends it from the ceiling. They record the
pendulum's period for each of 12 string lengths.*
