物理习题中有一类在解答过程中必须对研究对象的可能的物理状态、可能发生的物理过程或现象进行判断、讨论的问题 ,称之为讨论型习题 .学生在解答此类题时 ,往往考虑不周、丢三落四 ,因此有必要加强这类习题的教学 ,本文主要探讨造成物理习题讨论的几个原因及解法 .1　由矢量方 There is a class of physics problems that must be judged and discussed about the possible physical states, possible physical processes, or phenomena of the research object during the solution process. This is called a discussion type exercise. When students answer such questions, they often consider It is necessary to strengthen the teaching of such exercises. This article mainly discusses the causes and solutions to the problems caused by physical exercises. 1
