Torsion pendulums are commonly used in physics experiments to study phenomena such as torsional oscillations, torsional resonance, and the torsional properties of materials. By measuring the period of oscillation and other characteristics of the pendulum's motion, researchers can gain insights into the behavior of mechanical systems and the properties of materials under torsional stress. Torsion pendulums are also used in geophysics to measure the properties of the Earth's interior and in seismology to detect and study seismic waves.
