The compound pendulum consists of a rigid body swinging about a point within it. The period of such a pendulum is given by r=2iW[(h2+ja)/j,, ... 

Any body having the possibihty to oscillate freely under a gravitational force around a horizontal axis, not passing through the body s CM, is referred to as a physical pendulum. In this case, all points of a rigid body move along an arc of concentric circles. Consequently, for the description of a physical pendulum s oscillations, the rotational laws of dynamics should be applied.
