连接体问题一直是高中物理学习中的难点,尤其弹簧连接系统更是学生较难掌握的内容。由于学生对弹力大小和方向的变化过程缺乏清晰的认识,不易建立与之对应的物理模型并快速分类,导致面对这类问题时,出现解题思路不清、效率低下、错误率高的现象。因此,弹簧试题也就成为高考命题的热点,下面 Connector problem has always been a high school physics learning difficulties, especially the spring connection system is more difficult for students to grasp the content. Due to the lack of a clear understanding of the change process of the elastic force and the direction of the students, it is not easy to establish a corresponding physical model and quickly classify them. As a result, students face unclear problems in thinking, inefficiency and high error rate in the face of such problems . Therefore, the spring test questions will become the hot topic college entrance examination, below
