A physical pendulum experiment now becomes essential in Physics Education. A physical pendulum consists of a rigid object, with a particular shape and size, swung by a pivot point on the object. One of the often-overlooked requirements in measuring practice by this experiment is the small angular displacement. Nowadays, there is little or even no literature explaining the period formula of a physical pendulum with large angular displacement. A typical period formula is used very firmly, requiring this to be related to the approach used in its derivation. Thus, if the pendulum angular displacement is quite large, a correction should be made to the existing formula. This research is aimed to get the formula for determining the period of the physical pendulum experiments with various swinging angles, both small and large angles. After the formula was obtained mathematically, the results were compared to the experimental measurement of the physical pendulum period with various swinging angles. Through the mathematical analysis of calculus and the measurement of the physical pendulum period with the level of time precision measurement to microseconds, it is obtained that the physical pendulum period depends on the swinging angle value of the pendulum but not in a linear relation. This fact emphasizes the formula achieved from mathematical analysis.
