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

the ceiling. They record the pendulum's period for each of 12 string lengths.*
