How to learn physics to progress, how to learn physics well! How can I improve?

1。To pay attention to the study of theoretical foundations, we must keep in mind concepts, theorems, and laws. It is necessary to understand it from natural phenomena.

It's easy to remember. For example, the same car with the same slope, different materials of the road, the car slides at different speeds, so you will review the law of inertia, the object is forced to change the original state of motion, friction resistance, friction coefficient, the three elements of force, mass, weight, speed, distance, time, work, power, friction generated by useless work into heat energy, specific calorific value, mechanical efficiency. Wait a minute.

2。Focus on the improvement of experimental skills, for example, the components of circuits, the measurement of resistance, the measurement of voltage, the measurement of current, why are civil circuits connected in parallel? Proficiency in the use of measuring instruments.

3。Self-learning promotion and deduction. The first type is the reading analysis question, which allows you to analyze the principle of the existing test method and judge the right and wrong.

One is informational questions. Give you a bunch of equipment, what theories to use to back it up, and make measurements. One is the knowledge transfer question, which interprets common phenomena in life and confidently deduces an idea.

For example, if two people pull a rope together, and each person pulls a rope at different angles, analyze its effect.

In short, it is the essence of learning physics to study physical phenomena in depth and interpret them theoretically.

It's okay to pay a little attention to the subject of physics.

It's actually quite easy.

On the basis of doing more questions, physics is nothing more than a combination of several types of transformations, think more. Conservation of momentum, conservation of energy, analysis of force, electricity is power, active and reactive, etc., personal summary is very important In comparison, physics has a lot less to memorize than chemistry.

Physics is a difficult subject for students who are not good at rational thinking, so how can they learn physics well? I have compiled some learning methods for the study of physics for everyone's reference.

Maintain a good mindset

In the process of solving physics problems, there are often bad mindsets that affect us. These are the things we are trying to overcome. It's even more important to develop a good mindset!

A good mindset is to think of what you see! For example, when you see "inertia", you think of "quality"; When you see "combined velocity", you think of "actual velocity"; When you see "friction", first analyze whether it is static friction or sliding friction; When I see the "resultant external force", I think of "acceleration"; When I see "energy changes", I think of various corresponding "functional relationships" and so on.

Be justified in your speculation

Galileo, on the other hand, pioneered the combination of experiment and theory to derive solutions to physical problems. Thus overturning the error of Ya's empiricism and assumptions. Therefore, when studying physics, we should strive to be "well-founded" in drawing every physics conclusion!

Be able to derive your conclusions from physical formulas, theorems, and laws.

It is necessary to pay attention to the examination of the topic

The examination of the questions must be slow and careful. Special attention should be paid to outlining the "keywords" and "keyword eyes", which can not only increase the speed and accuracy of the examination of the questions, but also avoid errors in the examination of the questions. When reviewing the question, it must be combined with the image given by the question, and the general process or state should be drawn on the straw paper; When the specific physical situation is very clear, and the analysis is very clear, then write on the test paper.

At this time, the slow review of the questions will increase the speed and accuracy of the questions.

Grasp the basic formula

Special attention should be paid to basic formulas, laws, concepts. "Rote memorization will never make you learn physics! "The smartest students look for the source of mistakes in basic formulas and concepts, and are able to review a large amount of knowledge from a single mistake - the most important sign of whether a student is enlightened in physics!

The first spine is the first, and the textbook is read repeatedly. This step is crucial, and almost all top students have experienced it. Textbooks are the best teachers.

Many students will say, "The textbook is so simple, and the exam is so difficult, is it useful to see it?" "That's not right.

In fact, as far as I know, anyone who has a bad or mediocre score in physics is not a solid basic knowledge. They think they have learned well, but in fact they do not understand the most basic concepts and theorems. If you don't believe it, you can open the textbook table of contents and carefully review the relevant content section by section, and then you will understand what you don't understand.

For a physical concept, you have to understand it at a deep level. Let's say two small balls collide, what can you think of from that? What's wrong with momentum?

What's wrong with energy? You don't have to think about these questions when you have to do the questions. These questions may seem simple, but when you think about it, you can come up with a lot of questions. Moreover, such simple questions are the root of hundreds of millions of exam questions.

Second, do some simple questions. This second step, like the first step, is despised by many. They may think that doing those easy problems lowers their status, or that they are too busy with difficult problems to do the easy ones.

What is a "simple question"? It is those that directly examine basic definitions and theorems, such as exercises in textbooks and slightly more complex questions. The purpose of doing these questions is not to answer the right question, but to understand the question thoroughly and associate something from the simple question.

Some so-called puzzles are actually a combination of several simple problems.

Then, read more sample questions from the reference books and do some general questions of medium difficulty. Personally, I like to read the example questions in the reference book the most, because the number of questions is small, and it is typical, and the answers are very standardized. After class, do a few medium topics to practice, the effect is often very good, do not ask for more, a few are enough.

It's still the same old saying, think back to it when you're done.

Finally, for the difficult problems, look at them with an attitude of appreciation and playfulness. To be honest, there are no difficult questions in the current comprehensive exam, at most they are related to the reality of life. And the practical questions are often not too difficult, but the lack of reading the questions intimidates a group of people.

At least 70% of the questions in the comprehensive examination are easy or medium, so for most people, the focus is to lay a good foundation and do a good job in simple and medium questions; Besides, only when these questions are done well can we have the time and ability to do the so-called difficult problems. One more word of caution: the so-called medium difficulty questions are just simple questions that are slightly more complicated.

Hope it helps the landlord!

Don't dig the reputation and be blind to death to do the topic, find some example questions to see.

Junior high school physics is not difficult to be stupid, and the high school entrance examination is not too difficult, so it is necessary to record the questions that you did wrong in the exam and homework to figure it out.

Learn to draw inferences.

First of all, you have to be interested, and secondly, remember not to ask people at every time you do a physics problem, but to say to yourself: this problem is simple, I will definitely be able to do it. In this way, every time you finish a question type, you will firmly grasp and remember, so it is very important to remember every question you have done, before each class, you should ask yourself whether the content you want to teach today is previewed, preview is not the same as mastering it, but do not understand after reading the tutorial book and do not understand to stay, listen well in class, so as to reduce a lot of burden.

If you really don't have time to preview, you can prepare a book, you can remember what the teacher says in class, you don't have time to do it, that's your notes, you can remember them all at the beginning, if you are proficient, you only need to remember some important ones in class, remember, sometimes important teachers will only mention it, and will not write it down, only primary school and junior high school are more special, the teacher will write it down, but a high school class contains a lot of knowledge, the teacher will not remember it all, sometimes the teacher will not take notes, our physics teacher is like this, I never take notes, the notes are all written down by us in class, I am used to writing the day's notes and mistakes together, so that it will not be too troublesome to wait until the time of review, I like to catalog the notes, so a thick book of notes, it will be very convenient when I want to look through the homework.

After memorizing a lesson, remember to review Zheng Huai's debate and review, as long as you take a cursory look.

Pre-class preview, serious class, comprehensive class notes, and after-class review. It is not easy to do these four bright files, you need to persevere, you can put your homework away and don't put it too much, if you want to learn physics well, you need a good tutoring book to help you prepare, ask the teacher, and let him recommend a tutoring book for you.

Do more questions again: If you are in contact with more questions, you will naturally know the meaning of the questioner when you see the question, and the problem will be solved.

Finally, communicate more: whether it's asking for advice or helping others, it's a very important learning process.

Good luck with your physical progress!

1) Pre-class learning. The previous day the class talks about the content, the next day the teacher looks and finds out the real difficulties will listen very carefully to the difficulty of the teacher, the teacher speaks, you understand the ideas, if your original understanding is the same, you will deepen the image, if the teacher is talking about you understand differently, you can find your own problems and can leave a deep memory.

2) The class keeps up with the teacher's train of thought. What do you want the teacher to speak, listen to and think about. If you don't understand, or the teacher uses mathematical formulas, physics formulas and concepts, and you forget to keep up with the teacher's train of thought, then don't always think about these questions as soon as possible to write down the questions, so as not to affect the following lectures.

Ask the teacher to discuss with the students after class.

Review after class. Clarify the problems that the teacher talked about, and these knowledge points are in those causal relationships, these progressive relationships, and these parallel relationships. The teacher talked about the examples in the book, but the teacher did not speak with examples to do it again.

It's rare for someone to pick so many topics before doing this, which is very important because reading comprehension doesn't really understand these issues.

4) Clear connotation. The physical quantities represented by each symbol in the formula are, of course, clear, but the concepts and the physical meaning of the formula should be better understood. For example, acceleration represents the magnitude and direction of the velocity change of a physical quantity (which is the physical meaning of acceleration), and the definition of acceleration is a physical meaning that represents it.

The physical quantity can have different definitions, for example, there are three definitions of magnetic induction intensity (only one is learned in high school), but its physical meaning is the same. Generally speaking, the skills of physics problems, mathematics, physics and chemistry are memorized, but it is difficult to understand the content of any subject, physics confuses physical concepts and laws of physics theorems and physical formulas in mind, and will be replaced by stone. Physics can't help, but remember, rely on rote memorization to make mistakes.

Restart the scope of its application of the laws of physics and sort out the possible relationships between the laws of physics, and sort out the problems to pay attention to when you use this formula to analyze and deal with the problem. For example, f is the momentum theorem and external forces. Another example is that there are generally three ways to solve a mechanical problem:

Newton's laws of motion, the theorem of momentum and the law of conservation of momentum, functional relations. In this case, a better approach is to recognize that in addition to different approaches to a deep understanding of the relevant laws of physics, there are three ways to solve the same problem, and that is, a given problem.

5) Work independently. Some problems that he will not solve are normal, not to solve the question? The textbooks and handouts that I read don't seem to have any, and once again ask students and even students to look at themselves when they work, and never copy them.

The fine for doing a question is not too big to make a headline is to really understand the problem, especially the different types of questions, typical headings. To solve the problem, it is necessary to pay attention to analyzing the physical process, creating images, and thinking clearly.

6) Good unit summary of systematic knowledge.

I once heard about a Shanghai middle school student's summary of "more understanding, more practice, and more summarization". I think this method is a good way to summarize the essentials of physics learning in high school.

To understand more is to grasp the preview, listen to lectures and review, and understand the knowledge learned at different levels and from multiple perspectives. Preview can be divided into coarse reading and intensive reading. Take a cursory look at what you're going to learn and circle the important parts under subheadings.

Then read the circle part carefully for a deeper understanding, i.e., intensive reading. During class, you can purposefully listen to the teacher explain the difficult points and answer questions. In this way, the knowledge will be understood more comprehensively and thoroughly.

In addition to understanding and memorizing the formulas and theorems, we should also deeply understand the teacher's lecture ideas and understand the "central idea" of problem solving, that is, grasping the knowledge points of the example problems and prescribing the right medicine, what theorem formulas to apply, so as to make them organized and procedural.

More practice refers to both the practice of consolidating knowledge and the "practice" of mental quality. Consolidation of practice means not only completing in-class exercises, but also completing a certain amount of extracurricular exercises. However, it is not advisable to simply "question sea tactics", and some representative question types should be done selectively.

Students with a good foundation should also do some comprehensive questions and application questions. In addition, we should pay attention to adjusting our mentality and cultivate a calm and confident psychological quality.

To summarize more, we must first classify and sort out the classroom knowledge in detail, especially the theorem, and deeply understand its connotation, extension, derivation, application scope, etc., summarize the connection between various knowledge points, and form a knowledge network in the mind. Secondly, it is necessary to analyze and summarize the solution methods of various question types. Another way of summarizing is to analyze your mistakes and weaknesses after your usual practice and exams, so that you can overcome them later.
