How can I learn physics well in junior high school?

Persistence is required.

Clarify the basic concepts and familiarize yourself with where they come from and how they relate to each other.

It is necessary to do some questions independently, with quality and quantity. There should be a certain number of questions, not too many, not too few, but also a certain quality, that is, a certain degree of difficulty. Anyone who learns mathematics, physics and chemistry will not be able to learn well without going through this level.

Solving problems independently, sometimes slowly, sometimes detours, sometimes even unable to solve them, but these are normal and the only way for any beginner to succeed.

It is necessary to be clear about the physical process, and there is inevitably a hidden danger of solving the problem if the physical process is not clear. Regardless of the difficulty of the topic, you should draw as much as possible, some sketches are sufficient, and some should be precise to show the geometric relationship. Drawing can transform abstract thinking into figurative thinking and grasp physical processes more precisely.

With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.

Study materials should be well preserved, classified, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more. Marking means, for example, for practice questions, that the general questions are not marked, and the good questions, valuable questions, and error-prone questions are marked differently for future reading, and marking can save a lot of time.

It is necessary to attach importance to the knowledge structure and systematically grasp the knowledge structure, so that the scattered knowledge can be systematized. It is as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.

Preview has no effect.

There is a sentence in the physics book called "Learn physics with your hands".

I am a junior high school physics teacher.

Learn the concepts of physics and strive to achieve the "five skills".

In junior high school, students will learn a large number of important physical concepts and laws, and these concepts and laws are the basis for solving various problems

Expression: Be able to memorize and correctly describe the content of concepts and laws.

Expression: Clarify the expression formula of concepts and laws and the physical meaning of each symbol in the formula.

Understand: Be able to grasp the scope of application and conditions of use of formulas.

Deformed: The formula will be correctly deformed and the meaning of the deformation will be understood.

Application: Simple judgments, reasoning and calculations using concepts and formulas.

In fact, the most important foundation for learning physics is to be familiar with formulas and some theorems.

When you do the questions, if you think you can do it, but you always do it wrong. That's obviously because you're not practicing enough.

I'm going to teach you a stupid but effective method that I've used before, with a few steps.

1. Entrance exam. Go through the general topic first, and then write down the relevant formulas on the manuscript paper for later use. (If the formula is familiar and comes out casually, this step is omitted.) However, this can only be saved when you do the question and know how to do it when you read the question. ）

2. When you encounter a problem that you can't do, or you don't have a clue, you write out all the physical quantities in the problem, see what the question requires, and then go back to find out what formulas can be used to find the solution. If there are many formulas that can be used to derive this physical quantity, then you will see what known quantities the question gives you. Then find the right formula.

3. If you use the second step and find that there are one or two physical quantities in the formula that best suits you. Then you go back to those formulas and find the unknown physical quantity according to the meaning of the question and the known physical quantity. Finally, you can ask for it when you go back!

It is recommended to do more different types of questions to enhance your speed.

Take the class seriously, preview before class, and do questions after class, then don't talk about it. I'll just talk about the after-school time!

1. Apply what you have learned and learn to use what you have learned to solve some physical phenomena in real life.

2. Because the physics learned in the textbook is based on ideal conditions, some physical phenomena in life (not simple physical changes, or more than a few changes) are different from the physics in the book. So you have to learn to ask the teacher.

3. Do the exercises, there is no doubt that the tactics of the sea of questions are effective. However, it is best not to do all the exercises you buy, only do different types of questions, and doing the same problem more than 3 times is just a waste of time.

4. The questions should be targeted, and they should be aimed at the chapters or knowledge points that you do not fully grasp.

5. If you are for the exam, then it is recommended to study the syllabus more. Understand the key points and difficulties.

6. Help your classmates solve problems more often, because maybe your classmates will bring you a type of question that you haven't done yet.

7. Be accustomed to learning from various knowledge points. It's easy and easy to get started.

8. If possible, it is best to discuss with your classmates, after all, there may be different solutions to the same problem, so as to broaden your thinking. Because maybe, the next time this question is difficult to do with your method.

9. The formula should be flexible, and it is best to remember those principles. You can also reason about the connections between those formulas, because many formulas are interrelated and can be deduced!

I think the first thing to do is to be interested. Then do more exercises, memorize the formula, and understand the physical quantities in the formula. Write down some of the key points that the teacher said.

Actually, it's very simple, I started to learn physics very well in junior high school at that time, and I couldn't learn anything for a long time in between, but don't be discouraged, keep going, and there will definitely be a time when I will see the blue sky. In fact, the main reason is that physics in the third year of junior high school is more important, ask the teacher more.

Do more exercises, mainly to test comprehension.

I am a junior high school physics teacher, and I can say that it is not difficult to learn physics well, but it is not easy either. To put it simply, "Memory is the foundation, understanding is the key". First of all, you should eat the basic knowledge in the textbook thoroughly and absorb it into your own nutrition, such as:

Concepts, formulas, physical quantities, symbols, units, laws, etc.; Then the textbook or the usual supporting practice questions are answered; Finally, some representative typical topics are selected from the extracurricular books, which has achieved the purpose of further improvement.

In fact, no matter how much you say, as long as you are willing to learn physics well, think seriously and profoundly, and work actively and diligently, you will definitely be effective. Since you have this mind, this has the first step to learn physics well, and it is also a necessary condition, seeing you this, and thinking about many of my students, I am proud of you, proud of your parents! Believe in you, believe that you will reach the other side of success!

1.Good math helps a lot in physics;

Good physics and mathematics are basically better; Even if it is fast, it is very advantageous, and in addition, logic and drawing ability can also be reflected;

2.Comprehension, finding a way to understand all the knowledge, rather than just focusing on doing problems; But doing questions can help reinforce understanding.

3.Feeling and imagining, imagining yourself as an entity in a physical phenomenon, to feel the process of force, movement, and change.

4.It is very important (especially in relation to movement) to break down the whole process into different phases (from time, location, etc.).

The last unit of the first semester of the second semester of junior high school and the second semester of the whole book are electricity, the teacher said that this part is the most difficult electricity question is ever-changing, one step can not keep up, step by step can not keep up, I am now in the second semester of the second semester of junior high school, I don't know what the content of the third year of junior high school is, but you should take a good look at the content of the first two grades, will not ask the teacher or classmates, don't feel ashamed, think about it, after the exam a bad score is called a shame!

If you do this, I believe your grades will improve, but you won't suddenly become the first, be realistic, don't think there is any diameter, since you have the last period of the third year of junior high school, the most important thing is to study well.

Yes, that's how I was, and I did well in the exam, but I really paid a lot, bought some tutoring books, found a tutor, and then made up all the knowledge first. In the end, it is to do questions and questions, ask questions if you don't understand, know and understand, believe in yourself, and you will definitely be able to get a good score in the high school entrance examination.

1.Understand how the formula works.

2.Do more questions.

3.Remember theorem.

4.Connect with life.

Yes, as long as you find time to do more questions.

Yes, even junior high school drops, physics is much simpler than politics. But you have to step up your practice and work hard, believe you!

Yes, believe in yourself in order to succeed. Our teacher said: as long as you copy concepts, formulas, physical quantities, symbols, units, and laws every day. Grades will improve. In the exam, just bring the numbers into the formula!!

Junior high school physics is simple and not explained.

High school physics hurts.

First of all, we must be serious about this kind of problem, and we must rely entirely on ourselves.
