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.*
Length (cm) Time (sec) Length (cm) Time (sec)
6.5 0.51 24.4 1.01
11.0 0.68 26.6 1.08
13.2 0.73 30.5 1.13
15.0 0.79 34.3 1.26
18.0 0.88 37.6 1.28
23.1 0.99 41.5 1.32
