曲线运动中的追逐与相遇问题,常涉及到多个物体,每个物体运动情况不相同,比直线运动中的追逐与相遇问题更复杂。面对纷繁复杂的运动过程,学生常常理不清头绪,找不到解决问题的切入点,难以下手。笔者在实际教学中,与学生一起探究,运用转化的思维方法,将复杂的物理过程化整为零,从而达到化繁为简、化难为易的目的。具体说就是:首先依次分析每个物体的运动情 The chase and encounter problems in the curve motion usually involve multiple objects. The motion of each object is different, which is more complicated than the chase and encounter in the linear motion. Faced with the complicated process of movement, students are often confused about the clue, can not find the entry point to solve the problem, difficult to start. In the actual teaching, the author explores with the students and applies the transforming thinking method to reduce the complex physical process to zero, so as to achieve the goal of simplifying and simplifying the process and making the difficult and easy. Specifically: First, analyze each object’s exercise situation
