摘　　要：本文从刚体平动的实例出发 ,指出在高中物理教学中将刚体简化成质点所带来的种种弊端 ,进一步说明新编高中物理教材中引进力矩概念的重要性。Based on the examples of the translation of the rigid body,this paper points out that if the rigid body is simplified as the particle in physical teaching in senior middle school,it will bring us many disadvantages. Therefore,the writer explains the importance of introducing the concept of the moment of force to the new textbook of physics for senior middle school.

关 键 词：刚体 平动 力矩 平衡方程
