The learning of physics is modular and is divided into four modules: 1 The understanding of concepts cannot be simply memorized. When faced with a new physical quantity, it is important to understand its role in the actual problem solving.
2 Application of the concept: Once the concept is understood, there is no major problem in applying it. The solution to the problem is, to grasp, every sentence in each question is giving you conditions, as long as the conditions correspond to the physical quantities, and then substitute into the corresponding formula, you can solve the answer.
3 Derivation 4 Synthesis: In the various chapters of physics, except for the relative independence of optics, the others are closely related, and care must be taken to connect them with each other. 2. How to do the exercises:
When doing exercises, especially science exercises, it is necessary to grasp the relationship between quantity and quality. Mainly focus on the quality of the questions. "I" never bought exercises in high school, mainly after completing the questions in the book and the questions given by the teacher, I summarized the solution ideas for each problem.
The process of solving the problem is divided into: 1 Analyzing the physical process: abstracting the process into physical quantities 2 Using mathematics to solve the problem 3. Study habits
1) You should listen carefully in class, and as for the learning method, you should adapt the learning method to yourself, rather than allowing yourself to adapt to the methods that others use well. 2) Think more and ask more questions when doing questions. "I" have always been very slow to do the questions, but every time I finish the questions, I look at how I got them, see what I can learn from in the future, and achieve the effect of drawing inferences from one another, instead of leaving them behind after I finish them.
In this way, "I" will be fast when I take the exam, unlike others, and when it comes to the exam, I will be busy deducing. 3) Ask questions immediately when you make mistakes, discuss problems with teachers and classmates, and don't be shy. 4) Review over and over again.
5) For reference books, students who do not have very good grades should look for books that have better analysis and summary when buying, rather than books that simply give answers.

Physics and physics need to be understood... It's useless to just memorize formulas and knowledge points, and the key is to use them flexibly. If you know what knowledge should be used for what questions, you will be satisfied with your learning.

Introduction: Physics is one of the key subjects in middle school, and learning high school physics must start together.
1. Preview and review
We all know the truth that stupid birds fly first. Due to our weak foundation, physics learning must be ahead of others. Students with poor foundation are advised to prepare for class before class.
Old knowledge related to this can be reviewed. Because I have already studied on my own once, it is easier to keep up with the teacher's lecture when listening to the class, and I will not lose confidence if I don't understand. For the new knowledge that has just been learned in class, after class, we must review the whole process of its introduction, analysis, generalization, conclusion, application, etc., and compare it with the similar old knowledge in the brain to see if there is any contradiction, otherwise it means that it has not really been understood.
At this time, it is necessary to rethink, read and study again.
Second, you must be able to read
Being able to read is the first step in learning physics. It is important to read books in any subject. Don't underestimate the book.
Only by reading the book and seeing it thoroughly can we do the topic correctly. The same goes for physics books. Key knowledge points should be marked, with emphasis on understanding and memorization.
The order in which they are compiled is regular. Through this, we can correct the Internet knowledge framework diagram, have an overall understanding of knowledge, and know what is the direct internal connection between each knowledge point. Reading a book a hundred times does not exaggerate one's opinion, but reading a book must be read and thought about with questions.
3. Read extracurricular books
Read an appropriate amount of extracurricular books to enrich your knowledge and broaden your horizons. Practice shows that students with excellent grades in physics have read a lot of extracurricular books. Because different books and different authors explain problems from different angles and in different ways, readers can deepen their understanding of physical concepts and laws from all aspects, and learn many clever and concise ideas and methods to solve problems.
In this regard, I myself have experienced, and if I see more, of course my thoughts will come to life.

First, the foundation of primary school and secondary school must be laid, and second, you must be interested in this course to be able to learn.

The most effective way is that we can do some physics experiments, through physics experiments to improve physics scores, we can also ask a physics teacher to give us 1-to-1 tutoring, we can also improve physics scores, and we can also learn the knowledge we have learned before several times a day, and do a lot of questions can also improve physics scores.
-
You must study hard, you must memorize more formulas, you must do more relevant exercises, you must do a good job of preview and review, and you must improve your understanding.
-
Children should be allowed to develop a good study habit, improve children's learning efficiency, let children find their own learning methods, you can ask some top students for learning experience and skills, and then you should also do more questions in related aspects, so as to improve the performance of physics learning.
-
Be sure to do more relevant exercises, be sure to memorize more formulas, be sure to do a good job of preview and review, understand different terms, improve your understanding, and ask the teacher if there are any questions.

When reviewing and preparing for the college entrance examination, we should not only grasp the important knowledge points of the subject, but also comprehensively, systematically and completely review all the required knowledge points, so as to highlight the key points and cover a wide range. Key content: Knowledge points:
Gravity, elasticity, friction, electric field force, ampere force, Lorentz force, centripetal force. Theorems and Laws: Newton's Second Law, Kinetic Energy Theorem (Law of Conservation of Mechanical Energy), Functional Relations, Lenz's Law, Faraday's Law of Electromagnetic Induction.
1. First of all, we must change the concept, junior high school physics is good, but high school physics is not necessarily good. The knowledge of physics in junior high school is relatively simple, and the content is not much, which is easier to grasp. In addition, in the late third year of junior high school, through a lot of practice, through repeated intensive training, the proficiency level is improved, and the physics score can be greatly improved.
But a high score does not mean that you are good at physics and can learn physics. If the interest in learning physics is not cultivated, and there is no good study method, it is difficult to learn high school physics well. Therefore, first of all, we should change the concept that if you are good at physics in junior high school, you will not necessarily learn physics well in high school.
So lower the starting point and start from the beginning.
2. We should cultivate a strong interest in learning physics, interest is one of the driving forces of thinking, interest is a strong and lasting motivation for learning, and interest is the potential motivation to learn physics well. There are many ways to develop interest, and from the student's point of view, it should be noted that physics is closely related to daily life, production, and modern technology.
3. Learn to integrate knowledge points, classify the information that needs to be learned and the knowledge you master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system. This promotes understanding and strengthens memory.
Practice more and do more. The fourth learning method of physics in the first year of high school is to practice more and do more. There is a saying that a good memory is not as good as a bad pen.
If you want to learn faster and remember more firmly, you must also do more practice, that is, you have to spend time and effort to do more questions, practice more questions, and do each type of question more times, and it will be natural to do it, and it will be easy to master these knowledge points.
Mistakes recorded. The fifth learning method of physics in the first year of high school is to record mistakes. To learn physics, if you want to learn well, it is recommended to learn to sort out the wrong questions, buy a record book of mistakes, record them one by one, and do them again every once in a while.
Prepare in such a short time, unless you can put it for two months in the summer, don't do anything else, buy a competition book to do, about 500 pages (32 folios, other analogies), basically first talk about knowledge points, learn some knowledge points that are not involved in high school physics (concepts, theorems, such as angular momentum, Kirchhoff's law), do some related basic topics to strengthen the understanding and proficiency of conceptual theorems, and then do comprehensive questions, and finally do the preliminary and semi-final sets of questions to find a feeling, The finals are expected to be slim, and they are for students in your province who participate in competitions specially organized by the school. You also need to learn a little calculus, which is very useful for high school physics competitions, and it also has some benefits for your senior year of math (but not that much). >>>More
I think physics is more focused on understanding and application. It is not difficult to learn physics, the point is to understand, understanding is better than anything else, those formulas, laws, theorems must be able to understand, do more questions, apply the knowledge learned to the questions, remember those laws and theorems do not memorize, rote memorization is useless, it cannot be applied to the problem at all, to understand what it is about, how it came about, in order to learn to apply. If the grades are too low, don't set the goal too high, step by step, understand everything in the book before the third year of high school, and if you have time to review in the third year of high school, you must learn to apply what you have learned when you do the questions. >>>More
I have watched Brother Zhen's online physics class before, and it is very useful, so I summarized it myself, and I hope it can help you. First, it is necessary to be familiar with various physical concepts and theorems, and most importantly, to grasp the conditions under which they are applicable. They are our tools to solve problems, and understanding the functions of each tool is the premise of using tools. >>>More
