How to learn physics in high school to learn the door

There are not many types of physics questions, in fact, it is to memorize those typical physical model diagrams, understand?

Physics mainly lies in a kind of thought, when you seriously do the typical examples that the teacher has talked about one by one, when you make it, you will find that you have a kind of new gratitude, to grasp this feeling, day by day, if you can figure out all the physics formulas within a month, and know how to derive, then your physics will have a flying growth, understand?

Once you have mastered the formulas and the typical examples that you have already visited, you should continue to deepen until you know that one day you will find a sense of enlightenment, rejoice, you will have no problem passing 70 out of 100 in physics.

Remember what I said, physics lies in thinking, chemistry lies in memorization, and mathematics lies in a large number of problem types.

The most important ability to solve physics problems is to build a model. Whether it's mechanics, electromagnetism, etc. As long as you memorize some basic theoretical models and practice the ability to break down complex systems into multiple basic models, all physics problems can be solved with ease.

All high school physics students must develop two abilities: accumulating basic theoretical models and decomposing complex systems.

The main thing is the formula, but then there is an understanding of the basis of memorization.

Interest is very important, physics is not difficult, but the teacher is not good at it, in fact, it is very interesting.

Look at the basic equations and pay attention to correcting mistakes.

Get started with formulas and memorize a few typical examples! Do it right, you're still interested!

The most important thing is to listen carefully in class, I am from the past, I used to be at the same table with me, every time he listens carefully in class, I listen casually, go down and do a lot of questions, and review hard, but in the end he does not learn well, because you can't get what the teacher says you can't get from other places!

The second is to find that feeling, the simple point is to do more questions, and if you do more, you will have a feeling, so even if you get started in the future, even if you don't have to do a lot of questions, it will be very powerful! The premise is to listen carefully in class again!

1. The classroom must be listened to carefully, students basically spend a day in the classroom, if the classroom can not be missed to listen carefully, this is equivalent to building a house without even bricks, for the study of high school physics, the most important thing is to concentrate on listening to the class, pay full attention, do not open a small wheel to search for poor sales. The content learned in the classroom is the focus of physics learning, so you must listen carefully to the class, which is also the fundamental reason why most people can't learn physics well.

2. Poor foundation before class to preview, we all know the stupid bird flies first, due to our poor foundation, physics learning must be ahead of others, it is recommended that students with poor foundation must preview before class, so that the old knowledge related to it can be reviewed, if the new knowledge does not understand, you can mark out the focus of the class to listen, so that you can listen to the class with questions, because you have studied yourself, it is easier to keep up with the progress of the teacher's lecture when listening to the class, and there will be no loss of confidence and reluctance to listen to the phenomenon of not understanding.

3. Textbooks are thoroughly eaten first, students with poor foundation generally have not mastered textbooks, and even the most basic formulas and theorems have not been memorized.

4. Pay attention to physics mistakes, there is no need to brush a lot of questions for poor physics foundation, for the mistakes that occur every day, the mistakes summarized by excellent students, and the mistakes that the teacher focuses on explaining in class, we should conduct in-depth research in a timely manner, and classify and summarize them in time! Make the same mistakes and make mistakes again and again, and your physics grades will improve quickly.

1. Correct learning attitude. If you want to learn physics well, the first thing is to dare to endure hardships, cherish time, and study unrelentingly. Establish confidence, firmly believe that you can learn any course well, firmly believe in the transformation of energy and the law of conservation, and firmly believe that if you give a little, you should gain something.

2. Pay attention to the learning link. Among them, the learning link can be divided into eight links: making a plan, pre-class preview, concentrating on class, timely review, independent homework, problem solving, systematic summary, and extracurricular learning.

The most important thing here is: concentrate on class, review in time, work independently, solve problems, and summarize systematically.

3. Pay attention to the cultivation of self-learning ability. We can work on memorization, accumulation, synthesis, and improvement respectively. Memory:

In the study of high school physics, we should be familiar with the basic concepts, laws and some of the most basic conclusions, that is, the so-called most basic knowledge that we often mention. Accumulation: It is the work after memorization in the process of learning physics.

Synthesis: Physics knowledge is divided into chapters and sections, and the content that can be required by the physics syllabus is also one by one, which is not only related to each other, but also different from each other, so in the process of physics learning, it is necessary to continue to carry out small synthesis, and then carry out systematic synthesis after the knowledge of the third year of high school is completed. Improve:

With the memorization and accumulation of previous knowledge, and then careful synthesis, you can improve your problem-solving ability.

For some topics, we should first look at what the problem is, mechanics, thermal, electromagnetic, optics or atomic physics, and then clarify the research object, combine the conditions given in the topic, apply relevant physical concepts, laws, and can also use some physics first-level and second-level conclusions to obtain results.

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.
