Abstract

A new moment of inertia experiment apparatus different from the existing one has been developed, which does not require deformationof a sample in order to fix it to the apparatus. This new experiment apparatus was able to experiment with constant-shaped objectsthat did not deform the samples, so that it enabled them for conducting an experiment which is close to an ideal rigid model dealtin the general physics course. The new experimental apparatus was easy and accurate in measuring the physical quantity by using theexperimental principle of physical pendulum. In the results of the measurement of the moments of inertia of the six samples, all measurementswere made to be accurate enough to measure with very small errors within 1%. In addition, it has been found to be useful as anexperiment apparatus to understand the concept of the moment of inertia and to prove the formula for moment of inertia. Therefore,if the new moment of inertia experiment apparatus developed in this study is used in students' experiments, it is expected that studentswill be able to greatly increase their understanding of the concept of moment of inertia.
