摘要
刚体的转动惯量是刚体的重要概念,其测量方法较多但精确度不高.利用美国PASCO公司生产的传感器来设计和研究刚体的转动惯量,根据重力势能转换成平动动能和转动动能的关系来间接测出刚体的转动惯量,并对实验数据进行了分析和处理.
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.
