Learn Middle School Physics Feelings 5, learn Middle School Physics Feelings

I got it; I'm about to be a freshman in high school, and I know all about junior high school physics, but my biggest feeling is that I haven't touched these things for more than a month, and now those junior high school students' questions, some of the questions that I have done before, have forgotten a little.

Therefore, practice makes perfect, he is a physics teacher, as long as he does not touch physics for a few months, his level will definitely have an impact.

Physics in the second year of junior high school is just an entry-level physics, and it is not very difficult, you just need to gnaw on the books, and once you don't understand something, ask the teacher immediately, or come here to ask. Don't just ask the answer to the question, that won't do you any good, ask why this is right and why that's wrong, how should you think about this kind of question? What are the tips for solving these kinds of problems?

As for some of the things you haven't learned, you'd better understand them quickly during the holidays, come and know that it's okay to ask, ask teachers, and ask classmates, don't waste time on anything else, it's okay to relax appropriately, don't throw away your studies.

I regret it now, I haven't reviewed the books and exam papers for more than a month, I have forgotten a lot of things in junior high school, and the science things are okay, that is, Chinese, I have forgotten the ancient poetry and ancient texts, and I have forgotten a lot of English words and meanings.

I sincerely advise you to nibble on more books! There are very few books to use! 9011

It's super hard to write, so it's OK to write about what physics is a discipline of life or something.

Physics in junior high school includes measurement, preliminary knowledge of electricity, electricity and magnetism, heat and cold, changes in the state of matter, preliminary knowledge of sound, simple optical phenomena, optical instruments, mechanical motion, mass and density, and force.

In the third year of junior high school, you will also learn about pressure, sinking and floating, simple machinery, mechanical work, heat transfer, heat, the law of electric current, electrical work and power, energy, etc.

I hope I can help you with your doubts.

I am a junior high school physics teacher, and in fact, learning physics is very simple, it is a science. As long as you understand and understand this theory, you will almost never forget it, and junior high school physics is still closely related to our daily life, and many problems and principles can be learned in connection with reality. Hope it helps.

Junior high school physics is very simple, but mechanics is a little more difficult. My magic weapon is to listen carefully, review in time, do more exercises, and ask questions if you don't understand. I was very good at physics back then. What is practical is the basic principle, just stick to it, don't leave the basic principle.

Understand definitions and memorize definitions and formulas.

In fact, the definition is understood, and the general ones contain formulas, as long as these are synthesized together, physics is not difficult to understand, junior high school physics is still very simple, they are all intuitive things, as long as the definition or something is understood, it is okay, and the memory depends on itself. In addition, what phenomena can be associated with what you usually see, see what it is related to, many things in life are related to junior high school physics, practice makes perfect is also possible, that is, it will be slower, but the memory will be more solid.

In fact, it is useless to talk about as much as you want, and the most important thing is to ask your teacher for advice.

Read more books and listen to teachers!

I forgot what I learned in junior high school.,Tragedy.。。。

Physics is a new subject that we have added in the second year of junior high school, and I think it is very important to develop good study habits in the learning process of physics. In the study of physics, the first thing is to learn to prepare, and consciously cultivate the habit of pre-study. The objectives to be achieved in the preview are:

Know what to learn; Clarify which parts of the knowledge to be learned are basically understood, and which knowledge needs to be explained by the teacher during the lesson. Second, we must learn to listen to lectures with goals and focuses, which is inseparable from the preview, and only when the purpose of the preview is truly achieved, can we make the lectures have goals and focuses. Third, we must learn to complete homework independently, and the independent completion of homework here does not simply refer to not copying other people's homework, but also refers to not writing homework against textbooks and class notes when doing homework.

Refers to the ability to complete assignments independently. Grasp the three links of preview, lecture listening, and homework in the learning process, and summarize the knowledge learned every week.

Strengthen training and master basic physics skills. In the study of physics, there are two basic skills to be mastered: one is the ability to express problems in physical terms and standardize the writing of physical formulas and problem solving formats; The writing of physical formulas and the format of solving physical calculation problems should be standardized and proficient. They are the foundation for learning physics well.

The second is the basic operation ability of physical experiments. The operation skills of physics experiments must be mastered through a large number of hands-on experiments, and the operation skills can be found on the basis of mastery. During the experimental operation, you should use both hands and brains, ask yourself more questions, and then find a way to solve the problem.

It is necessary to learn to observe physical phenomena, learn to analyze and summarize physical phenomena based on physical phenomena, combined with existing physical knowledge, and draw conclusions.

Pay attention to the basics and focus on understanding physical concepts. In the learning process of physics class, it is important to pay attention to the understanding of physics concepts, basic concepts and basic laws. When learning every physical concept and physical law, we must not just memorize it mechanically, but also have imagination and correct thinking ability, so that we can truly understand its essence.

Therefore, in the process of learning physics knowledge, we must pay attention to the learning of physical concepts in each chapter, and pay attention to understanding every physical concept and every physical law. In the process of doing questions, we should pay attention to the foundation, start from the basic questions, lay a good foundation, and then do difficult problems. In the process of doing problems, you should use your brain more, think more, have a deep understanding of the problem, learn to be flexible, and lay the foundation for future learning.

When we study physics, it is not enough to listen carefully in class to learn physics well, we should put what we have learned in class into life, and understand it more carefully in life. In this way, you can not only consolidate your knowledge, make what you have learned more profound in your mind, but also may find some knowledge that you have not found in **, and your knowledge will be higher improved.

The concept is dead, the subject is alive. When you memorize the concept well, it means that your foundation is good, it means that you are willing to work hard, but everyone will memorize the physical concept, to be honest, I don't memorize the concept of this thing, my key is to do more questions, study the topic, and understand the concept at the same time, and will not forget to do the physical body to have "scenario analysis thinking" in the future, because the topic is alive, the topic of the dead formula is what we take the test less in the middle school entrance examination? It is a series of possible situations in which the object is moving, and finally get the result, don't think about the formula as soon as you get a question, but analyze it first.

In this way, you can learn physics well.

My disadvantage is that I don't know how to memorize things, and I don't bother to memorize them, so I am relatively weak in liberal arts. It's a partial subject, but I'm still very confident in physics. Don't doubt yourself, believe in yourself, your brains are not benzene, because you still know how to learn, but you didn't develop the habit of analysis before, and you will be fine in the future, believe in yourself.

Textbooks are the foundation.

Don't do too much of the exercises.

However, it is important to be clear about what is in the textbook and the exercises after class.

To strengthen the understanding of experiments, it is best to have the habit of pre-study before learning physics.
