It s the third year of high school at the beginning of the semester, and physics is my weakness, so

In the past, in the physics class, I used to take out the tutorial book, sort out the most basic principles at the beginning, put it in a notebook (with a tree diagram or network diagram), and then summarize the content of a section and a chapter after I have a general direction, and you will find that the knowledge of the book is regular, and after mastering the basic principles, you have to start doing the questions, I suggest that you start with the college entrance examination questions, first do multiple-choice questions, you can exercise whether the basic concepts are wrong, if you don't understand something, you must turn the book, and then write it back in the notebook, if you have a big question, you can do a simple first to sort out the general idea Use kinematics or dynamics to build your own problem book, mark the answers that you don't understand, cultivate your senses, think more, and you will find that you will gradually have ideas.

Well, I should be okay with physics, so I'd like to give you some advice here.

There don't seem to be multiple-choice questions in physics for the college entrance examination, at least I'm here. Well, for multiple-choice questions, you can ignore the uncertain options first, and choose the ones who will choose first, at least get the basic score. If you encounter a big question in the exam that you can't do, first sort out your thoughts, first understand what this question is about, and then write a few formulas to solve this kind of question.

Substitute the data to calculate and see what conclusions can be drawn, and often you can have some ideas when substituting.

Usually, if you review by yourself, you must know how to summarize the knowledge points, for example, if you have a pendulum, you can draw an image of a pendulum, mark ** is v maximum, ** is a maximum, the direction of centripetal force, the combination of graphics and words can help memorization.

I'm not good at speaking, I hope you understand what I mean.

Let me tell you the easiest way, buy a physics review material, be comprehensive, but not too thick, because your summer vacation is not long, do it seriously, do every question, don't let go of any topic you think is not important, I reversed it last year, really.

In fact, physics can still be learned well through hard work, and many students have a problem.

First, the basic knowledge has also been mastered, but the basic knowledge is not well understood. Causing knowledge to be right and wrong, and laying the root cause for not knowing where to start when doing problems in the future. This is also the reason why I don't know how to do the questions, and the teacher doesn't think it's difficult when I talk about it.

Second, you can't summarize your trivial physical knowledge into a line and connect it into a network. It is to summarize the knowledge points and figure out the connections and differences between the knowledge points.

It is not difficult to overcome these two points, but it requires a process. My experience is that when learning knowledge, we should pay attention to the basics and go from the shallow to the deep. It's not too late for the third year of high school, act now, divide the volume, review (study) independently in chapters, and buy basic materials (for example:

Ren Zhihong's "Optimization Design" is good), close to a material review can be, each chapter should have its own independent summary, read more textbooks, think more, summarize more, I believe that your physics can catch up, and become an advantage of the subject!

To see how weak it is, you should need to make a reasonable plan.

To be honest, even if you are the first in physics, you may be confused in the final exam.

Sometimes it's better to do more questions and find patterns in them than to memorize formulas.

Of course, it is more important to have a proper open mindset, and you can't just do it brusquely.

First of all, you must be interested in physics, which is the most important thing, but also do more questions, memorize the formulas and figure out the ins and outs of the books.

Do more questions, think more about the basis for doing the questions, and remember some common test questions.

Have a perseverance and persevere.

Be careful, not self-righteous, and go more with this feeling.

Do more mid-range questions, do difficult problems appropriately, and be confident when doing them.

Be sure to pay attention to the lectures.

Go to a cram school and don't care about the little money.

You can take a look at it yourself, write down what you don't understand, and then ask others.

Physics is about the "principle of all things", and there is a wealth of inexhaustible knowledge of physics everywhere around us. As long as we keep a curious heart and pay attention to various natural phenomena and life phenomena.

Emphasis is placed on regular learning(1) Study the textbook.

The army does not fight unprepared battles, and the same goes for learning physics. The books for the new semester have been sent, and I hope you can pick up the physics textbook, open the picturesque chapters, and follow the table of contents to get a general understanding of the content of this semester; Before each chapter and each section of the class, preview again in advance, you have a lot of doubts, waiting to uncover the mystery with the teacher in class; When revising, the textbook should be reviewed over and over again, "read the book a hundred times, and its meaning will come to you", and each time you will make a new discovery.

(2) Listen carefully.

Genius is not born. Whether it is a new class, an experimental class, an exercise class, or a review class, every "exam champion" can make full use of the class time, listen attentively, follow the teacher's ideas, think positively, outline the key points from time to time, mark the ones that are still unclear, or record the new questions that arise, so that learning is efficient. Learning is a process, constantly spurring oneself, strengthening one's self-observation of one's own learning beliefs, and perseverance, in order to reach the realm of "learning" and "learning".

Attaching importance to physics experiments Physics experiments are the foundation of learning physics; Science is the goal and method of learning physics, and nature only benefits practitioners. Therefore, we should have the courage to experiment and be willing to **. We should actively participate in the experiment, and when the teacher does the demonstration experiment, we should observe carefully and think positively; When you walk into the laboratory to do experiments, you should consciously cultivate your serious, meticulous, and realistic scientific attitude and experimental ability.

In addition, we need to use the whole world as our textbook to see what experiments can be done with the objects around us. Do more small experiments, small productions, engage in some small inventions, write a small **, and develop a good habit of having the courage to experiment and be willing to explore.

Pay attention to the organization and classification of knowledge When the knowledge learned increases, it is easy to make mistakes and mix up. Therefore, try to follow the framework mapped out in the text and in some tutorial materials to help with memory and comprehension. Sometimes, classifying concepts appropriately can simplify the content learned, highlight the focus, and have a clear context, so that it is convenient for oneself to analyze, compare, synthesize, and generalize;

You can constantly systematize scattered concepts, constantly incorporate new concepts into the system of old concepts, and gradually establish a clear conceptual system in your mind, so that you can avoid detours in the process of learning. In this way, you can not only deepen your understanding of the basic knowledge of the gods, but also get twice the result with half the effort.

1. Grasp the preview link and learn physics with questions, so as to disperse the difficulties and highlight the key points in a timely manner.

In order to learn physics well, it is necessary to cultivate students' self-study habits and grasp the preparatory link.

First reading: Read the text from beginning to end, circle the key points, doubts and difficulties, form the preliminary structure of physics knowledge, and be able to highlight the doubts and difficulties in a targeted manner when listening to the lecture, and grasp the center.

Second look: The illustrations in the textbook are written by the editors to help students understand certain physical phenomena, the illustrations are vivid and interesting, and students can learn knowledge in a happy way by looking at the pictures.

Three dos: Physics is a science based on experimental operations, and the pre-class preview must be combined with the content of the textbook to preview the "experiment".

Four thoughts: There are reflection questions at the end of each section of the textbook, and you can try to see if you can solve them after reading the book, so as to enhance the purpose of listening to the lecture and grasp the key points.

Physics, to be honest, when you get the hang of it, it's going to be a mess.

It's simpler than math because math examines things that are elevated in books that aren't available in books.

But the physical stuff is all in the book.

1.Look at the textbook carefully. Read sentence by sentence. Don't let go of the example questions, read them carefully.

2.When doing a big problem, the formula is very important, and the basic score in the big topic is very easy to take, just set a few formulas.

3.Don't be afraid of it mentally. Physics is an ever-changing thing, and when you are not proficient, you can do more targeted questions. For example, if mechanics is not good, I often do the theme of mechanics.

4.Be calm. Physics requires thinking. There are many inferences and formulas in physics, and as long as you have a firm grasp of the root definition and the general formula, everything will not be difficult.

Good luck.

First of all, I understand that I have not mastered those knowledge points, do more questions in this area, and slowly experience, I really can't, find an experienced teacher for one-on-one tutoring.

1.Take out the wrong questions, find out the reasons for the mistakes, prescribe the right medicine, check and fill in the gaps;

2.Summarize the knowledge points learned and the types of questions in the exam to ensure that you can know how to solve similar questions in the future;

3.Preview what you will learn for the next semester.

Make up the foundation first, the foundation is very important.

It is recommended to find a tutor, the easiest and fastest way.

Keeping in mind the conservation of energy, the conservation of momentum, mechanics and collisions, taking all the cases into account, the topic is simple, the velocity of the object contains kinetic energy, the height contains potential energy, there is energy loss in sound and heating, doing work on the object can convert mechanical energy into other energy, and so on, it is nothing more than the transformation of several types of energy, and the total energy remains the same. In the case of collision, it is simpler, the conservation of momentum is the mainstay, supplemented by the energy conservation formula, and the formula is used to calculate together.

Electromagnetism, figuring out the left-handed rule and the right-hand rule, what rule is used for electromagnetic (energy) conversion, conservation of total energy, conservation of work.

Of course, the formula should be memorized.

When you see the topic, first determine what the topic is, whether it is motion, work, collision, current resistance, or particle-electromagnetic.

Work class pays attention to the initial energy (momentum), force, and terminal energy (momentum) of the object

Pay attention to several formulas for current, the series current is the same, the parallel voltage is the same, and pay attention to whether the number of turns of the coil is proportional or inversely proportional to the voltage.

Electromagnetism pays attention to the rules for judging the direction of magnetic fields and currents.

It's a good idea to talk to a teacher and ask him to help you analyze it, isn't it?

Physics is actually not difficult in the college entrance examination!

Pay attention to your disintegration ideas when you usually do the questions, and you must have a clear understanding of why I wrote this way at every step, he came to test me or something, what traps and so on, train yourself slowly, don't worry, you will have a good harvest.

For students in the third year of high school, physics is really not easy to understand, sometimes there is no enlightenment, I don't understand, I can't understand, I can't be in a hurry, take a good look at the topic, usually the physical quantities in the question are expressed in letters, and then the physical formulas that can be used are put in, nothing more than those principles, conservation or something, and finally the required physical quantities are expressed in letters, the results are calculated, and they are basically like that.

Specifically, you can also find a few similar topics to demonstrate to you.

In the third year of high school, it is not more than usual, it is recommended to divide the assessment into sections and review with focus. For example, if a student of mine has a poor foundation, I recommend focusing on the form and content of the 8 multiple-choice questions, as well as the first big question. Guaranteed accuracy.

Physics, in fact, has to lay a solid foundation to understand the knowledge of various principles, and you can understand it in turn, because the so-called difficult problem is not the difficulty of the problem itself, but a combination of a variety of physics knowledge, anything can be done, mechanics is lame, and the big problem is easy to not do... So it's the foundation that's the key, and then it's about divergent thinking.

The other thing is to do the questions, but to do the weak ones, otherwise you will always do what you are good at, which is a waste of time.

Personally, I think that if you want to learn physics well, you should first start with the basics, and only when you learn the basics can you grasp the comprehensive topics.

Therefore, it is recommended that you memorize the basic physical theorem formulas.

Idea: Physics knowledge and life knowledge are very appropriate, when considering physics, it is best to have a life model in mind, integrate physics knowledge into life, and use physics knowledge to solve physical phenomena in life; Learning: When learning, we should comprehend and understand the meaning of physical formulas, integrate all physical knowledge, understand the characteristics, relationships and differences of each knowledge point, and use our brains and think more; Practice:

The consolidation of physics knowledge is inseparable from the practice of exercises, if you want to have a good physics score, you have to carry out a lot of exercises, think more, use more pen, make more drawings (and it is a clear and clear graphic), think comprehensively when doing problems, do not take it for granted, a physics problem will integrate multiple knowledge points, so it is best to review and reflect after completing a problem; Wrong question set: Concentrate the questions that are usually easy to make mistakes in a book, and open the wrong question set book to do the questions in it whenever you have time, this process will be very cumbersome, but the effect is still very good.

Actually, physics is not very difficult. Because what it reveals is the common phenomenon and essence of our lives, and you should be very interested in it.

I think it is because you didn't pay attention to the lecture during the lesson, so you didn't know anything about what the teacher was talking about, and you didn't have any interest in the subject.

It won't be hard soon. First of all, you must like the subject of physics from the bottom of your heart, and then listen carefully to the lectures, and after class, you must memorize many conclusions and phenomena in the book on the basis of understanding, and you need to train them to practice and use them flexibly.

Of course, if you already owe a lot of lessons, you'd better take the time to ask the teacher not to get up.
