A torsional pendulum (Fig. $\PageIndex{1}$ ) consists of a mass $m$ attached to the end of a vertical wire. The body is then rotated slightly and released; the body then twists back and forth under the force of the twisting wire. As described earlier, the motion is governed by the rotational version of Hooke's law, $\tau=-\kappa \theta$ .
