Prawns, can you tell me how to learn physics 15

1.Pre-study, it's important. You can use some tutorial books that explain comprehensively and have a certain degree of difficulty.

Recommend the "Synchronous Guide" issued by the school 2Be sure to listen carefully in class and don't get distracted. 3.

The homework must be done, and you will not be able to look at the answers and imitate the answers and solve them again. That's enough.

The most important thing is to combine with reality, I used to study physics and never memorize by rote, physics is different from chemistry, remember the simplest formula, and you can convert it to each other in later use.

Personally, I think the core idea in physics is the conservation of energy.

No matter which chapter you study, the conservation of energy is the same.

For example, magnetism generates electricity, and electricity is vivid. The core idea is nothing more than the mutual transformation of energy.

When you learn force analysis, you can also understand force as energy in several different directions, which can be at rest or at a constant speed, indicating that the force on the object in all directions is equal, and the equal can cancel each other out.

Your understanding is not good, and there is something wrong with the way you do the questions. When I was in junior high school, I focused on the understanding of key knowledge, and in high school, I focused on the understanding of basic physical phenomena. Your problem is comprehension, so it is recommended that you review the textbook more often, build your understanding of the basics, and then complete the corresponding textbook questions based on your understanding.

After force analysis, you just need to remember the orthogonal two-direction equation is basically 5ok pull, the circular motion is simpler, since you remember the formula, just put the formula aside, see which equation the known and unknown conform to, sometimes you need to use some geometric knowledge, the three laws of the universe will not be tested in high school, you just need to remember that it is an equivalent derived formula, what is equivalent to the solar system as a ball problem with uniform mass, and then exaggerated is a particle.

I think there should be a lot of experience in buying a book of materials and brushing the questions, as well as physics learning, I think it is necessary to listen carefully in class, some basic knowledge and basic problem-solving methods and problem-solving thinking teachers will mention in class.

I've seen a lot of ways to learn physics. But the most important thing is the foundation. Basic concepts, basic models, and basic methods.

Wrong question set = = really, this is too important, and there is a circular motion and the laws of the universe or something drawn on paper, the data like what centroid spacing are marked by themselves, and it is quickly understood, well, you can add a buckle, and show it to you.

Science focuses on understanding, if you only remember the formula, and don't understand the split understanding of the formula, you can't learn well; And some questions are the superposition of multiple knowledge, indicating that some knowledge is related! ~

I have only just come into contact with physics in my second year of junior high school, and I feel that learning physics is an interest, and I can find a lot of problems when I am interested.

Learning methods: 1. Memory: In the study of physics, memorize the basic concepts, laws and some of the most basic conclusions. Incomplete memory will have an internal adverse effect on the formation of knowledge of the entire physical system, so learning physics should start from memorizing basic concepts and laws.

2. Accumulation: On the basis of memory, collect relevant information about physics knowledge in textbooks and reference materials, and analyze and classify different knowledge points in the process of collecting and sorting out to find out the similarities and differences. Through repeated memorization, the knowledge is comprehensively and systematically, and the connection between formulas, theorems and laws is closer to achieve the purpose of accumulation.

3. Synthesis: Chapters are continuously synthesized during the learning process, and systematic synthesis is carried out after the semester. The content of the chapters is interconnected and analogous to each other, and the knowledge is integrated and connected, so as to improve the understanding of physics from the synthesis.

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way: a vacuum is really empty, there is nothing.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.

First of all, read the textbook several times to ensure that you understand various physics concepts, which is the basis for learning physics. The second point is to complete the preview task assigned by the teacher before class, if the teacher does not assign it, then complete the preview of the corresponding chapter first, including supporting exercises and after-class exercises, etc., so that you have a certain understanding of the content to be learned, and you also know where you don't understand, and you can listen to the class in a targeted manner. Thirdly, after completing the day's study, find a time in the evening to review what you have learned today to deepen your understanding and impression of the knowledge.

Fourth, be sure to understand the exercises thoroughly, rather than just brushing them. For the exercises that you do wrong and can't do, when looking at the standard answers, you must know why the answer is written this way, and you must be able to explain it to yourself, so that you can truly understand and remember the use of the formula. Fifth, you can make a mistake book, collect the exercises you did wrong and the questions that you think need a little problem-solving skills, take it out and look at it, do it, and avoid falling twice in the same pit.

Sixth, after you have a good enough grasp of physics, you can try to answer questions for your classmates, and in the process of answering, you can also sort out the knowledge you have mastered. Hope.

The three basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient. In the process of learning physics, it is very useful to summarize some concise, easy-to-remember and practical inferences or assertions to help solve problems and learn physics well.

To do the questions independently, you should do some questions independently (meaning not relying on others) and with quality and quantity. Solving problems independently, sometimes slowly, sometimes detours, but this is the only way to success.

The physical process should be clear about the physical process, and there will inevitably be hidden dangers in solving the problem if the physical process is not clear. Regardless of the difficulty of the topic, try to draw as much as possible. 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.

Listen carefully in class and don't get distracted.

The notebook class is mainly for listening to lectures, and there is also a notebook where there are some things to write down. Knowledge structure, good problem solving methods, good example problems, things that you don't understand well, etc., should be written down. After class, I also have to organize my notes, on the one hand, to "digest well", and on the other hand, to supplement my notes.

Study materialsLearning materials should be well kept, classified, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more.

Time is precious, and without time there is nothing to do, so be careful to make the most of it, and using time is a very masterful art.

To learn from others, we should learn from others with an open mind, learn from our classmates, learn from the people around us, see how they learn, and often communicate with them "academically", teach and learn from each other, and improve together, and we must not be self-righteous.

Knowledge structure should attach importance to the knowledge structure, and it is necessary to 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.

Mathematics is so important for learning physics that calculations depend on mathematics. Learn mathematics well and make good use of mathematics as a powerful tool.

Physical activity: A healthy body is the guarantee of good learning, and vigorous energy is the guarantee of high learning efficiency.

To learn physics well, you must have good observation and abstract thinking skills, and you must be good at studying and using your hands and brains when you encounter problems. Pay attention to learn the most basic things, and the definition of the law must be clear.

Studying physics is the same as studying other disciplines, first understand the theory and definition. In the process of learning, you should be full of imagination and understand various knowledge points in physics, such as mechanics, optics, electricity, and the laws and states of their motion. This is to do the problem, and any subject must be practiced repeatedly in practice.

If you want to learn physics well, you must first learn the basic knowledge well, and then when the basic knowledge is laid, we need to focus on the after-class exercises in the book, and then slowly draw inferences from one another, and gradually deepen the difficulty of the questions.

When you find a type of exercise that is better classified, you can find the rules of certain knowledge points when you do the exercises, and then slowly form some ways and methods to do the problems yourself.

Don't memorize by rote!! In addition to learning physics in class, we also need to operate in real life and understand ...... deeply

In life, we should observe more and study more! Use your brain!!

Physics is a discipline that is very close to life, and it is not possible to learn about the world by learning it in the classroom.

Be sure to be good at discovering and thinking about the problems in nature!! Interest is generated!!

Physics comes from the trapped orange nature!! Born from nature!

Don't put too much pressure on yourself in the subject of physics, don't.

Alarmist. Target.

Listening to others say that it is difficult to learn will produce pressure, but in fact, every study of envy Lu science will not feel difficult when you enter it!

I hope it helps, I'm in my second year of junior high school, and I'm not bad in physics (to tell you a little secret, I actually don't finish my homework sometimes, but I'm still good in physics, and sometimes I'm still the highest grade).

As for me, I'm just very curious!! So I'm interested in physics!! A teaching tool for our physics lessons.

When I go home, I make it myself, so I can see the construction for myself and deepen my impression! I did it myself.

It was also exhibited in the school year and used as a teaching aid.

Hope it helps.
