PocketLab Voyager is perfect for performing an experiment on torsional harmonic oscillation. Voyager is taped to a mass hanging from a spring. The mass is given both an initial vertical translation and a torsional twist and then released. While simultaneously bobbing up-and-down and twisting back-and-forth, the two motions are recorded by Voyager. The period of the translational motion is recorded by the acceleration sensor. The angular velocity sensor concurrently records information for measuring the period of the torsional oscillation.
