The “V” shaped bifilar arrangement of the string insures that
the pendulum will swing back-and-forth in the same plane.

Measuring the Period of a Pendulum:
DataStudio: When using DataStudio software with a Science-
Workshop interface, go to the Experiment Setup window and
click the icon of a digital channel on the picture of the inter-
face. Select the “Photogate and Pendulum” choice from the
“Choose sensor or instrument” panel. Click OK.
When using DataStudio software with a PASPORT interface,
go to the Experiment Setup window and click ‘Setup Timers’.
Select the “Photogate and Pendulum” choice from the “Choose
sensor or instrument” panel. Click OK.
Check the PASCO web site at www.pasco.com for information
about using the SPARK Science Learning System (SPARK
SLS) to measure the period of a pendulum.
Data Recording: Align the pendulum with the photogate so
that the pendulum will block the photogate beam as the pendu-
lum swings back and forth. Pull the pendulum back a few cen-
timeters and release it so it swings through the photogate. Press
‘Start’ to begin recording data. Let the pendulum swing several
times, and then press ‘Stop’ to end recording data. Use a Table
display to view the data.
Using this experimental setup, students can investigate the
relationships between length and period, mass and period, and
amplitude and period. In all cases, the effects of air resistance
are held constant since the shape and size of the pendula are
identical.
