How do you learn physics in high school? From junior high school to high school, how should I learn

In fact, there are so many knowledge points, and the question types are also limited, as long as you understand it, take out a few more questions for analysis and analysis, so that you can connect a lot of knowledge points, and it is not necessarily that you want to do more questions, die to do questions, so that you analyze a few questions better than do n questions, it is recommended that you take out a few more questions to analyze, find out the difference, so that the next time you do such a question, it will be easy.

Listen to the teacher's lecture during class, understand the knowledge points taught by the teacher and apply them flexibly, you can try to do the questions, if you don't apply them flexibly, then you need to make questions to strengthen it.

Pay attention to daily life, pay attention to the processes of material phenomena when observing.

When writing questions, it is no problem to learn well in connection with reality.

You can't be clever in high school.

The amount of questions is a must, and to be honest, the sea of exam questions in China is still quite effective.

Doing a good job in the mentality of junior and senior high school physics learning is a learning bottleneck that every student needs to break through. Compared with junior high school physics, high school physics has more content, and it is necessary to learn a lot of new content that has not been learned in junior high school, such as the synthesis and decomposition of forces, Newton's law of universal gravitation, the theorem of momentum, the law of conservation of momentum, the nature of light, etc. It is more difficult, and some will move from qualitative discussion to quantitative calculation, such as the relationship between force and motion, the concept of kinetic energy, electromagnetic induction, nuclear energy, etc.; Competency requirements are higher; Flexibility is required.

Physics learning in high school should not only learn physics knowledge, but more importantly, improve the ability to learn physics knowledge and apply physics knowledge, and learn some commonly used physics research methods.

Therefore, there are newer and higher requirements for students in high school, which is a leap forward for students in all aspects. For example, the leap from qualitative to quantitative, from figurative thinking to abstract thinking, from simple logical thinking of single factor to complex logical thinking of multiple factors.

The first year of senior high school is an important period in students' learning path, and it is also a critical moment in students' psychological development. A considerable number of students are outstanding in junior high school, and after entering the school in the first year of high school, there is no problem when learning the movement of forces and objects, and they feel that high school physics is nothing more than that. Problems arise from the beginning of learning Newton's laws of motion, and later on when learning about curvilinear motion, laws of gravitation, momentum, mechanical energy, etc., the problems get bigger and bigger.

If you can't adjust your learning mentality and methods in time, you will feel that physics is difficult to learn, or even can't learn it.

A small number of students due to the weak willpower to bear the setbacks, shaken their will, the learning and development channel is blocked, the spiritual world will be self-closed, people become depressed and pessimistic, so that they lose self-confidence, and set up an obstacle for themselves psychologically, so that the learning problems accumulate more and more, forming a vicious circle, and eventually will give up the study of physics, so they made the decision to abandon science and literature in the first year of high school.

In view of this situation, we should first eliminate psychological barriers, and realize that learning physics is as difficult as learning any other course, and if physics is really difficult to learn, we should muster up the courage and make the greatest determination to use all our skills to learn. If you put in a little more time at the beginning, you will be able to learn well. In addition, even if physics is difficult to learn, it is the same for all students, the starting point is the same, and you should not admit defeat psychologically, you should be confident in learning physics well, and then adopt a learning method that suits you, you will definitely be able to learn physics well.

Physics in high school is more esoteric, so every student has to organize a knowledge accumulation book and a problem book, and when you organize all the content, you will get better progress.

The physics subject in junior high school is relatively simple, as long as you follow the physics teacher to do more basic experiments and practice more familiarity. In high school physics, a lot of time and experience are invested in making a summary.

In fact, physics should lay a good foundation, and it is also necessary to give more physics formulas and memorize some problem-solving routines.

You should keep in mind the relevant physics formulas, and at the same time you can do several more sets of questions to find ideas.

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.

The key is still in the classroom, to take good notes, and then do a good job of after-class exercises, to learn systematically, and most importantly, to understand some basic knowledge, to understand the derivation of formulas.

It is to think more, think more for yourself, that is, to analyze by yourself, after the teacher has finished listening and understanding, you should complete it independently once, do not do the question based on experience, analyze the specific situation, and ensure that you listen carefully in class! As long as I listen carefully in class, I make a workbook to take the test of 80, and I do five books at the same table to get more than 30!

The key is to understand the definition of the theorem, there is no problem, the first step, you need to memorize the definition of the theorem, and then do some special topics on the definition of the theorem.

Preview before class and review after class.

There is no shortcut or quick fix for learning mathematics and physics, don't think about those opportunistic things, of course, there is a strategy or method for learning. I was a freshman in high school in 2003, although it has been a long time since I graduated, but I still have some ideas about studying physics, my physics grades are a little better than other grades, and my method is like this:

1.Don't memorize formulas, you will never get a good score. It is very important to read more books, to read books as carefully as learning Chinese and English, to read the texts, not to think that science subjects do not need to read books and texts, but to carefully read or study the definitions, concepts, physical meanings and physical backgrounds in the texts.

Many students memorize all the formulas in the physics books, but they still don't know how to do the questions or they can't do them if the questions change slightly, which is a lack of understanding of the definitions, concepts, physics background, etc., so it is really important to read the texts carefully. If you read the text carefully, you have a certain understanding of the concepts, definitions, physical background, etc., or when you understand it a little, you will find that the formula will be remembered naturally, and it is a deep memory, that is, it will not be forgotten after a few years, and when you do comprehensive questions, you will find that when to use what formula will naturally emerge in your mind.

2.It is to do a sample problem in the textbook to see the "example problem" clearly, the example problem is to do a direct explanation of the concept and the use of formulas, to do a do, understand and understand. The practice questions and exercises at the back of the textbook should also be done well, these topics are selected by the experts who compile the book, and they are very representative, you must know that whether it is the usual final exam or the college entrance examination in the future, it is based on the textbook proposition, so we should pay attention to the topics in the textbook.

Many of the questions in the college entrance examination are changed from the questions in the textbook, or have the same physics background as the questions in the textbook.

3.When you have time, write down the basic formula, and see clearly that it is the basic formula, what is the basic formula, which is the defined formula, such as:"Speed"It is a physical quantity that describes the speed of the object's motion, its magnitude is the ratio of displacement to time, the velocity is a vector, and the direction is determined according to the specific problem.

Then v=s t is the basic formula that is defined. If you remember the concept of speed, isn't it a formula? However, there are many formulas in physics, and they will not be completely defined formulas, so those derivation formulas will also be deduced and derived by themselves, and the derivation formulas are doing problems, using basic formulas, and understanding the problem-solving ideas of physics.

4.Do a little practice, this is essential, the topic is not more but fine, pick a good extracurricular tutoring exercise, it is best to have a detailed explanation. As for which book to buy and go to the bookstore by yourself, everyone's situation is different, depending on your own situation.

The study of physics does not rely on rote memorization, but on the understanding and application of concepts and laws, and the knowledge of why it is the way it is and why it is the way it is. At the same time, this understanding and application should generally be combined with specific scenarios or models.

It's been eight years since I graduated from high school, and lately I've been reading a lot of other people's physics problems.

The first question should be asked, do you believe that a person's IQ is high or low?

I don't believe it, I believe that everyone's IQ is different.

It doesn't matter what you read, no matter what you do, how old you are, how many years you've walked, these are your experiences.

But why do some people just can't learn? In fact, most of the students do not know what they are facing, so they don't know what they are facing, so they don't know what the method of facing is the so-called smart people, not high IQ, and the so-called, deaf, clear, he is not confused to master physics, let alone confused, you have to master a discipline, just like catching animals, you must first find his weaknesses, this is much easier than catching animals, the key to physics, mechanics, grasp the line, you can control the kite, understand.

To master physics, mechanics, electricity, conceptual formulas, is only meaning, can not be spoken, you can only continue to be proficient, do problems, do an hour and a half a day, your physics grades will be very good, grasp the weaknesses, master the structure, the relationship between formulas and formulas, quantifiers, changes, motion, forces, and functions, these are enough to understand (the last is to remind that most of the students will fall in the force analysis, the right hand rule, the formula, these three things must be grasped, if their minds are not careful enough, Or practice more).

Do more, ask more. The other gods and horses are all floating clouds.

Select D, the ball B will not recover instantaneously because the spring deformation will not recover, so the spring elasticity is maintained, so that B remains stationary instantly, and the acceleration is zero.

And the ball A loses the rope tension and is only affected by the gravity along the downward slope of the component mgsin37°, and the spring pulls on A, this pulling force is equal to the gravity of B along the downward component of the inclined plane, mgsin37°, so ma1=2mgsin37°a1=
