力学导论中关于机械能守恒的几点注记
Remarks on the conservation of mechanical energy in introductory mechanics
摘要：
我们在普通物理课程的背景下讨论功能原理和机械能守恒定理。其动机是这样一个事实，即所有现代力学导论文本都显示了同样的概念上危险的陈述，除了抹杀机械功的概念，降低功能原理的重要性之外，还导致能量守恒定理的错误应用，同时消除了它与机械动量守恒原理的关系。
英文摘要：
We discuss the work-kinetic energy theorem and the mechanical energy conservation theorem in the context of general physics courses. The motivation is the fact that all modern texts on introductory mechanics show the same conceptually dangerous statement that besides obliterating the concept of mechanical work, diminishing the importance of the work-kinetic energy theorem, leads to erroneous applications of the energy conservation theorem and at the same eliminates its relationship with the principle of the conservation of the mechanical momentum.
