Abstract

The moment of inertia theorems, crucial for determining the moment of inertia of objects with diverse shapes, were assessed through experimental analysis using a physical oscillator in the Mechanics Laboratory at the Faculty of Physics. Results from this study demonstrate that the theorems of parallel axes and the additivity of moment of inertia can be accurately validated through the oscillator experiment. The physical oscillator emerges as a valuable tool in mechanics, physics, and engineering labs, facilitating precise determination of moment of inertia and acceleration due to Earth's gravity. Employing the physical oscillator method for experimental investigations of moment of inertia theorems necessitates adopting a unique perspective on experiences, yielding valuable results through comprehensive data analysis.
