First of all, the biggest obstacle to learning physics is mathematics, because physics is more logical, just like mathematics. If you want to learn physics well, you must thoroughly understand every concept and basic figure in the textbook. When solving physical problems, graphics can often provide us with many known conditions.
Second, the habit and ability to think independently. There are many kinds of physics problems, but few concepts and formulas are impossible. You must think positively after class, and you can't ask slightly difficult questions. Thinking can sort out and reintegrate the learned knowledge.
Third, don't get into trouble. Physics is very rigorous, but many physical problems or questions are based on theory, and it is impossible to achieve this condition in real life. For example, without friction, it is impossible to achieve in real life. So don't let the details affect the solution of the problem.
Fourth, besides listening carefully in class, we should be good at summing up problems after class. We should think and summarize some questions raised by the teacher ourselves, and don't wait for the teacher to "instill" in the next class. Junior high school is a new stage, not "nanny education", so self-study is also a lesson in junior high school.
Fifth, the investigation of physical experiments, physics should not only test theoretical knowledge, but also rely on calculation ability, but also test practical operation-experimental questions, which is often the most serious problem. It is the basic requirement of senior high school entrance examination to cultivate their observation ability and experimental operation ability consciously and purposefully.
