运用动量矩定理解题中常见错因分析

Analysis on the common errors of the students with moment of momentum theorem

动量矩定理是解决动力学问题的基本定理之一,在此主要分析了学生用动量矩定理解题常见错误及错误原因,提醒学生在应用动量矩定理解题时应注意公式的适用条件和范围。

It is a basic theorem to use moment of momentum theorem when solving a problem. In this paper, we analyze the common errors and their causes and remind the students that the movements in the moment of momentum theorem are all related to the inertial reference frame.
