How to learn physics well in high school, and whether there are good physics materials

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.

I feel that the textbook is completely interpreted and not bad, but the questions are a little less, and it would be good to buy a workbook full of questions, and I am not an advertising landlord.

On the basis of the above two, try to use mathematical thinking to think about the physics problem when solving the problem, it is generally wrong to solve the physics problem with ordinary physical phenomena, do not ask the teacher or classmates when you encounter the problem that you feel difficult, this is only useful for this topic, it is not helpful for the whole study of physics, you should find and cite the knowledge points of physics, find your own way to solve it, and after you solve a certain amount of problems, there is nothing to stump you, I started physics very poorly when I was in high school, Later, I learned to quote knowledge points to solve problems and integrate knowledge points, I scored 120 points in physics when I took the college entrance examination, and I took 118, of course, the questions in our physics college entrance examination that year were very simple.

First of all, grasp the most basic foundation and master the formula. Then have faith in yourself. The most important thing is to analyze the physical process of each problem, as long as you understand the motion process of things, and then use the formula.

Pay attention to the things around you, and understand how things work. Take your time and do some typical questions, and be sure to have confidence in yourself.

After thoroughly understanding the basic knowledge in the textbook, all the information is a floating cloud.

This is something to consider.

It depends on whether you are a sophomore or a senior in high school.

If you are already about to take the college entrance examination, there are not many points you want to improve in a short period of time, but after all, there is still a way.

If you are just entering the second year of high school, it will take time to hone if you want to study more easily in the future.

The way to improve your score in a short period of time is that if your score is less than the passing line, you will grasp the concept and grasp the basic question type, if your score is in the passing line to the excellent line, do 20 big questions a day, it is necessary to meet the test standards, don't bother yourself with the competition, it is best to only do it yourself, you will not do it will be annoying, if you understand the basic question type, it means that the concept is familiar, do some questions that you can do to enhance your confidence, but not too simple.

If you want to learn physics easily, it will take at least half a year, of course, if you have a strong comprehension ability, but you don't know how to face the problem, then the time can be less.

The first is to summarize the main points of your knowledge, physical mechanics and electromagnetism, accounting for 80% of the points, generally except for electricity, it will not be too difficult, mechanics includes the important thing is the conservation of momentum, the conservation of mechanical energy (I personally prefer the conservation of energy, but the range is large, unconditional, but relatively few people can accept), electromagnetism, must be proficient in judging the right-hand rule, the most prone to error.

In addition, a formula is a thing that is easy to harm people, remember, it is very simple to be proficient in a formula, when you do a problem, you substitute each value of the formula into its unit, just like a fixed number, the left and right sides must be the same unit. After doing this for a long time, think about the formula S=VT(M=M S*S), v=at(M S=M s 2*S), or G=MG(N=KG*M s 2), of course, you need to know some basic unit conversions. n=kg*m/s^2)

In fact, high school physics is only very basic, it is not like Chinese English to memorize a lot of things, nor is it like mathematics that exhausts the method, but many people are very reluctant to accept an unfamiliar subject, don't be afraid, physics is still physics, it is just a subject derived from mathematics, much simpler than mathematics.

You don't need to listen to the teacher talk about the concept in class, but you must spend a little time to listen to the teacher's lectures, and some people have said that you can listen to the teacher, but you can't do it yourself, you must not copy notes, then you will not be able to keep up with the speed, follow the teacher's train of thought, and then bury your head in the notes, and eventually you will become lost. Generally, it is good to spend ten to twenty minutes listening attentively in a class, remember the concept after class, don't do too many questions, and do one question, which is better than a hundred questions, don't bother yourself with the questions. Do a little, but if you can't do it, you must remember that it is to remember where you stopped, not to remember the topic.

Understand the principle of formula derivation and master the application.

It's useless to say more, don't get distracted in class, it's over if you get distracted, remember. When doing the questions, do it yourself, remember the question types and formulas, and be able to use them. Start with the basics, and then consolidate comprehensively.

A smart brain physics requires a certain amount of talent.

The basic difference is mainly based on books, and the basic things are thoroughly understood and then expanded.

And then I did a lot of questions, and I was like that, and it wasn't bad.

The important thing in physics is not the textbook, but the practice questions. You have to do crazy questions to understand what physics is learning, and that's the key. If you do it to a certain extent, you will realize a lot. It also has to be summarized.

1. Clarify the learning objectives.

Independence in the application of new knowledge. First of all, it is necessary to clearly put forward the specific purpose of learning, and the purpose of learning is the guarantee of learning and gain. Purposeful learning can stimulate strong mental energy.

The determination of the purpose of learning should be dispersed into each learning, that is, each learning should put forward specific and achievable goals, so as to avoid getting lost due to the lack of goals and avoiding the failure of the learning plan.

2. Be diligent in thinking.

If we clearly understand the common essential factors between various knowledge points in terms of content and methods, and have a high level of generalization of existing knowledge and experience, and can reflect the essence of physical phenomena and processes, we can accurately classify new problems according to their characteristics, and we will avoid guessing, blindly trying, or rigidly setting formulas regardless of the surface characteristics of the problems.

In learning, physical conceptual models, physical process models, and typical problem-solving processes can all be abstracted into "prototypes" in the learner's mind. In the process of learning, we should pay attention to the learning and training of basic concepts, basic laws and basic skills; Pay attention to the study and thinking of typical examples; Focus on the analysis of typical physical processes; Pay attention to inductive ideas, methods, and skills.

3. Practice in a timely manner.

At different stages of learning, constantly examine and compare what you have learned or the exercises you have done to find out what they have in common. This common denominator can be varied, for example, conditional, conclusion, formal, physical process, thinking method, problem-solving skills, and so on. Timely training is to prepare for analogical thinking, classification of propositions, selection of ideas, methods, and skills, and acceleration of the change of ideas in the future.

Fourth, timely summary.

When the learning is over, it needs to be summarized. Firstly, the category, nature and meaning of knowledge are analyzed, and the knowledge learned is classified into a knowledge system to form a new knowledge system. It is necessary to understand the nature of knowledge and its role from different perspectives.

understand the nature, interconnections and differences of the components of a knowledge system; Master the rules, methods, and steps for solving various topics, and form a certain cognitive structure. Understand the internal logical relationship between concepts and laws and the corresponding dependence and analogy.

Learning is important in perseverance, and benefit in method. I hope that you will have a clear understanding of the purpose of learning, and that you will be able to adjust and control your learning methods according to the purpose and make continuous improvements.

Learn physics well, logical thinking ability is very important, how to improve logical thinking ability, class is very important, listen carefully to the teacher's analysis of problems, learn the teacher's ideas for analyzing problems, the next thing is to do your own questions, do more questions, do different types of questions, according to the teacher's ideas to analyze problems, physics is not difficult, it is really important to have a good teacher! But you can't blame the teacher for not learning well, do more questions, ask more classmates with good grades, listen to the ideas of students with good grades to solve problems, and think about your own analysis of mistakes!

For those formulas, it is best to see how it is derived, so as to distinguish which formulas can be used in which situations, and then know the physical meaning of the formulas when they do a good job, and then do the questions.

Classes are the most important, the teacher is talking about the essence of things, a lot of self-exploration will draw a lot of time, if you feel that physics is difficult, you can roughly preview it before class, listen to the class more targeted, and then go back in the evening to review the notes and deepen your understanding.

As soon as you have a question that you don't understand, you should immediately ask the teacher and classmates to understand it, which will affect the later learning and not let the questions pile up.

Of course, physics still needs to do more questions, and science requires a lot of practice.

Let's cultivate an interest in physics, and if you are interested in physics, physics will not be bad.

Physics is about thinking more and making fewer mistakes, thinking less and making more mistakes, and not wanting to be all wrong.

My advice below is for high school students! To learn physics, we must understand the meaning of the physical formulas in it, and secondly, we must combine drawing, especially mechanics. Physical mechanics and kinematics are undoubtedly the two most important parts, and these two parts mainly describe physical principles through formulas, so we must understand the meaning of physical formulas, and then when doing problems, we must start from the problem and work back from the back, rather than starting from the formula.

Through the problem, determine the physical formula to be used in the problem, and then there must be some variables in the physical formula to be used, and then use other formulas to find these unknown variables, and finally bring in the formula to operate. For example, find the acceleration of a moving object.

The first thing that comes to mind is Newton's second law: f=ma; a=f/m；At this point, one or both of f and m may be unknown, and then we can do that. f can be obtained by drawing a diagram of the action of the force, by the synthesis of the force, while mass can be obtained from the motion characteristics of the object.

Finally, bring in a=f m. In short, the physics of the first year of high school is the most important, mainly mechanics and kinematics. In the future, whether it is the conservation of energy or various electromagnetic forces, you will have to use the principles of mechanics and kinematics, so it is recommended that you consolidate the physics of the first year of high school.
