理论力学运动学关键概念和知识体系梳理

Teasing out the key concept and knowledge system of kinematics in theoretical mechanics

总结理论力学运动学教学中的问题和经验,通过数学基础引入梳理运动学关键概念及点的运动学与刚体运动学的逻辑联系,建立运动学新知识体系,为理论力学运动学教学和教材改革提供参考。

The teaching problems and experiences of kinematics in theoretical mechanics is summarized, we tease out the key concept and logical relation of particle kinematics and rigid body kinematics by introducing mathemat-ics ,and then establish the new knowledge hierarchy, we show that these will provide an effective reference for the teaching and textbook reform in theoretical mechanics.
