电磁感应中的动力学问题,一直是高考的热点.这类问题的知识跨度大、综合程度高、涉及的知识面广,求解这类问题的难度较大、方法比较灵活.不过动力学问题的求解一般有两条线索:力学线索、功能线索.现就这两条线索的动力学规律的选择策略总结如下.一、力学方程的策略力学方程包括平衡方程和牛顿运动定律,是研究某状态下物体受力的规律.由于 The dynamics of electromagnetic induction has been a hot spot in college entrance examination.The knowledge span of such problems is large, the degree of synthesis is high and the knowledge involved is wide, so it is more difficult to solve such problems and the method is more flexible. There are two general clues to solve: mechanical clues, functional clues.Currently these two clues on the choice of kinetic law strategies are summarized as follows.First, the mechanical equation of the mechanical equations including the equilibrium equations and Newton’s law of motion is to study a state The law of force on the object
