Education, which penetrates the method of physics, emphasizes the importance of analyzing and dealing with the problem of transformation and conservation of energy.
Second, the key, difficult analysis
1. The law of conservation of mechanical energy is an important law in mechanics knowledge. Knowledge is a key. Especially the law of the applicable conditions and physical significance, and specific applications as high requirements.
2. The law of conservation of mechanical energy in the understanding and application of suitable conditions, for most students, although after a phase of learning, often is not enough, still all sorts of mistakes. It also suggests that this is the difficulty of teaching.
