Negative Exponentially Damped Harmonic Motion from a PocketLab Pendulum

Rich ·
This experiment allows one to do a quantitative investigation of the damped harmonic motion of a swinging pendulum. The pendulum is a piece of wood about a yard long from a Michael's hobby shop one end of which has been attached to a PocketLab by a rubber band. The other end is taped to the top of a doorway, allowing the resultant pendulum to swing back-and-forth as shown in the image below. The y-axis is perpendicular to the XZ plane of the swinging pendulum. Therefore, the main item of...

Quantitative Experiment to Determine the Relationship Between a Pendulum's Length and Period

Rich ·
PocketLab is a perfect device for determining the quantitative relationship between the length of a pendulum and its period of oscillation. Pendulums of known lengths were made from balsa wood strips such as those available from Michaels and other hobby stores. The photo below shows six such pendulums of lengths 15, 30, 45, 60, 75, and 90 cm alongside a meter stick. The picture shows that PocketLab was taped with double-stick mounting tape to the pendulum whose length is 45 cm. The photo...
