动能定理是高中力学中十分重要的规律,它揭示了做功与动能变化之间的关系.动能定理不仅在解决力学问题时可以大显神威,而且在涉及动力学的有关电学知识中也会得到广泛应用.动能定理也是高考中必考的热点内容.因此,在物理教学中,必须弄清动能定理的涵义,必须掌握动能定理的运用方法.本文就动能定理的涵义和应用做初浅的探讨.一、理解五大要点1.动能定理的内容外力对物体所做功的代数和等于物体动能的增 The kinetic energy theorem is a very important law in high school mechanics and reveals the relationship between work and kinetic energy changes. The kinetic energy theorem not only shows great influence in resolving mechanical problems, but also in the relevant electrical knowledge related to kinetics Therefore, in physics teaching, we must clarify the meaning of kinetic energy theorem and must grasp the application of kinetic energy theorem.In this paper, the meaning and application of kinetic energy theorem are briefly discussed. First, understand the five major points 1. Kinetic energy content of the external work done by the algebra and equal to the kinetic energy of the object by
