Abstract

The rotary inertia of rigid body is an important concept,its measurement accuracy is not high.In this paper,we design a new method to test the rotary inertia of rigid body by the sensor produced by the PASCO Company of the United States,and according to the relationship between gravitational potential energy and kinetic energy,rotational kinetic energy to indirectly measure the inertia of the rigid body.In the same time we analyse and process the experimental data.
