Second, perhaps more children are not interested in asking why often, are not sensitive to things around them, or have persistent beliefs, or are not good at finding and solving problems, so learning physics may not be easy. For such children, I suggest you always force yourself to ask why. After mastering some of these methods, practice makes perfect, and you can be as relaxed and happy as the students mentioned above. How to force yourself? Find some of the most common phenomena in life and get to the bottom of it. For example, in winter, the heating is hot, which is very common. There is a lot of implied physical knowledge, and there are also many questions that can be asked. Why is the heating hot? Where does hot water come from? How did you get to my house? What is the fuel for boiling water? Where does the fuel come from? Why use this fuel? Why use water instead of other liquids to fill the heating ... as long as you have the heart, there are many problems. In this way, in the process of finding answers, we can not only increase our knowledge, but also cultivate our habit of exploring questions and persistent pursuit. In addition, the difficulties encountered in the process are also a test, which is conducive to cultivating will and "fighting ability." As for whether the final result is correct, whether science is not the most important, the most important thing is the process.
Third, if you don't have this awareness, but you are about to start school in the eighth grade, and you want to get good grades in physics, then learning from the school teacher is the only way to learn physics well. Teachers are professional, and some experienced teachers can make students get twice the result with half the effort. In the process of learning with teachers, there will be many problems. If students can take the initiative to seek answers as mentioned above, that is the best. If not, then at least they should ask a teacher to solve the problem.
