First of all, you have to put your mind in a good state of mind, don't think that physics is difficult, as long as you have the right method, you will find that physics is the best to learn. If you want to learn physics well, the main thing is to understand and master the physical quantities, laws, and theorems of physics, and not to memorize them. For example, when you see this physical quantity, you first think about what acceleration is, do you understand?
Instead of being lazy and blindly memorizing how it is calculated, I always think that it is okay to memorize the formula, and such memory is easy to forget, which causes me to always feel that physics is difficult, and the formula is always unable to remember, and the further I go, the less confidence I have.

1. Memorizing the basic formulas, concepts, and laws in the book is the premise of learning physics, some people say that the key to learning physics is to rely on understanding, but I don't think so, even the formula can't be remembered, how to understand?
2. On the basis of mastering formulas, concepts and laws, it is necessary to achieve the purpose of understanding through certain exercises. The purpose of the exercises is to identify your own shortcomings and correct them.

If you are a student of science, then if you are not interested, you will not be able to learn well. Mechanics is the most important part of the first year of high school, and even occupies a very important position in the college entrance examination. Therefore, mastering force analysis is the most basic skill, and mastering vector triangles is the key to solving mechanical problems.
The laws of conservation of energy and the law of gravitation require skillful application. This lays the foundation for the college entrance examination to solve the last comprehensive question.

Before reviewing, read your textbook thoroughly and attach a plan:
1: Make your own study plan in advance.
2: Review, preview, summarize, and take notes in advance.
3: Familiar with every knowledge point we are involved in, ask if you don't understand, do more, practice more.
4: Do a good job in each question, summarize it, and learn to draw inferences.
5: Change from passive to active follow-up every time.
If you don't understand something, even if it's very simple, you have to understand it, and you must not be embarrassed to ask teachers or classmates because it's simple.

Figure out every concept, every formula. At the same time, you should be good at summarizing, summarizing the different topics you have done and the different models you have seen!

1. Pay attention to the analysis of physical processes, and do not just set formulas, which will make it difficult to deal with difficult problems.
2. Connect with reality, but cannot answer questions with life experience, there are interference factors in life experience, and use formulas to derive conclusions.
3 The best way to know the formula is to do a good physics experiment. 4. Analyze the key sentences (in the textbook) thoroughly and grasp the foundation solidly.
5. After doing the above points, solve more problems and improve physical energy.
Force. These points are summarized by me in my physics studies, with reference to the advice of teachers and many comments on the Internet.
Physics, it is not difficult to learn well, this is a few experiences I have when I am studying, I hope it will help you: >>>More
In fact, there is no shortcut to this, and it is necessary to have a sea war. >>>More
Physics covers a wide area, including the electronic aspect of a lot of worth learning, now a lot of microcontrol technology is to learn physics to do, usually used mobile phones, computers, refrigerators, washing machines and other circuits, control motherboards are related to physics, this is daily, the mechanics of physics can be learned well enough to understand why the planet rotates, revolution, if there is a meteorite over the Atlantic Ocean in the morning where will fall, small to if I throw stones to the pool to use how much effort to use, etc., I think the value of physics lies in influencing our lives, social progress, and human development, and the value of learning physics lies in better research on things, better inventions and creations to improve life, and make human science more civilized and developed. Study physics well, I now hope that science is developed, and the robot nanny is popularized for 100 yuan a day for 10 years to be responsible for washing dishes, washing clothes, and cleaning.
(1) sharpening the knife is not a mistake to chop wood, the study of physics, first remember the formula, the formula is a tool for solving the problem, the formula can not be remembered, many problems are equal to "0" generally you can only remember the basic, other too complex temporary use in the use of the basic formula to push out. In the past, I had to summarize the formulas for a period of time, and organize and memorize all the formulas and some rules that I had gained from experience to use to solve problems. >>>More
I don't recommend you to study science, because you shouldn't like science very much, if you do, you will be very good in junior high school physics, and it is not difficult to learn physics in the first year of high school, and you should be able to learn it well. I also don't agree with what the above said, in fact, science mainly depends on understanding, of course, the basic theories are to be able to know, a question you understand the formula will not, can only say that you do not remember the concept of the formula, but if you can't understand the question will not be done, even if you know the formula. In fact, science is all related, like when I was in school at that time, I was good at science, so I was good at mathematics, physics, chemistry, biology and even geography. >>>More
