Period and pendulum length for a number of string and mass pendulums
constructed by physics students. The same mass was used throughout, but the
length of the string was varied from 10cm to 16 m.
Arguments
Format
A data frame with 27 observations on the following 3 variables.
length
length of the pendulum (in meters)
period
average time of period (in seconds) over several
swings of the pendulum
delta.length
an estimate of the
accuracy of the length measurement
