In the matter comprehension question, because the examination question is not thorough enough; or the understanding of the physical process and physical model is not accurate enough; or the application of the mathematical method to solve the problem does not give the actual physical meaning, etc., it will mislead the object understanding problem and solve the problem. There is an error. The following is an analysis of some typical mistakes in the junior high school physics exercises for readers’ reference.
