高中物理中的有些问题要涉及三维空间,而空间题对学生的想象力及抽象思维能力要求较高,并且学生学习立体几何一般比较滞后,这样导致空间题通常较难,学生难以理解与掌握,因此需要引起重视并加强该方面的方法训练.下面本文将借助几道典型题的剖析来探讨剖解空间难 Some problems in high school physics involve three-dimensional space. Space problems have higher requirements on students’ imaginations and abstract thinking ability, and students generally lag behind in learning three-dimensional geometry. As a result, space problems are often difficult and difficult for students to understand and master. So need to pay attention to and strengthen the method of training in this area.This article will help with the analysis of several typical questions to explore the difficult space to dissect
