刚体转动惯量平行轴定理的教学讨论

The Teaching Debate on the Parallel Axis theorem of Rotational Inertia

结合教学,提出对刚体转动惯量平行轴定理的几点教学讨论,指出不少教材里证明过程中的概念错误,并介绍一种较严谨的证明方法及该定理的一般推广式.

Combined with teaching, this thesis has advanced some argumentation on the parallel axis theorem of rotational inertia and has indicated some errors in the proving process in some teaching materials. Furthermore, a more precise proving method and a common extensive expression of the theorem have been introduced as well.
