普通物理学中动能定理的几个层次及其应用

Layers and application of kinetic energy theorem in common physics

用统一的数学表达形式表示不同模型的动能定理,突出了动能定理的本质,提出按模型分层次理解和应用动能定理教学体系。

This paper describes different models of the kinetic energy theorem in unified mathematic formula,gives prominence to the innate character of the kinetic energy theorem,advances teaching system on basis of the different models and different layers of understanding and application of kinetic energy theorem.
