动量和能量的综合问题是高考命题的热点,而弧形槽模型则是其中的经典模型。这类题型综合性强、灵活性大、分析能力要求较高。若我们在复习阶段采取就题讲题的方法,不但课堂效率低,而且不便于学生知识网络的构建。因此,在物理专题复习阶段,采 The integration of momentum and energy is the hot topic of college entrance examination proposition, while the arc groove model is one of the classic models. Such questions are comprehensive, flexible, demanding analytical skills. If we take the problem-solving method in the reviewing stage, not only will the classroom be inefficient but also not convenient for the construction of students’ knowledge networks. Therefore, in the physical review phase, mining
