There is still a month to go before I get 30 points in physics How can I improve my grades quickly

College Entrance Examination Physics 110 points full score, if only 30 points, then explain the most basic knowledge of physics, you still have not mastered, high school physics is divided into such a few large blocks, dynamics, electromagnetism, optics, so many parts, and these are related to each other, in fact, physics is very simple, as long as you grasp the key to the question, write a few important formulas, most of the scores have already arrived, because it is already this time, it is too late to sort out the system from scratch, My suggestion is to take a book of physics exercises first, to be the kind of neutral, every time you do a question, you have to conduct an in-depth analysis of that question, you have to learn to draw inferences from one another, you have to figure out what you want to test in this question, what are the formulas related to this knowledge point, what are the precautions for doing this kind of question, and what are the easy mistakes, so that each question is deeply deducted from it, so insist on doing 10 sets of questions, and dare not say anything else, there must be no problem with physics over 70.

I didn't think I could get a grade in science, because I was always coping with understanding and memorizing, but if I could go up to a higher level, everything would be solved. The best thing to do is to do the questions. Choose a book with good content and wear it, there should be no problem.

If you have any questions, ask me directly

Build a notebook of mistakes, cut out the questions you don't know and collect them in the book, keep looking at the questions you can't and then build a notebook of the subject, copy down some basic concepts and classic example problems, remember what you should remember, basically that's all, I wish you a qualitative breakthrough.

Read more books to understand the wrong questions.

Calculation questions, you write down the formulas involved in each question, you can score, and then you can score points according to the formula to bring in the data, like this, in general, you can pick up 10 points.

Figure out the most important points of knowledge. For example, Newton's laws of motion, mechanical energy, the movement of charged particles in an electric field, magnetic field, electromagnetic induction.

Back to the formula, and take a good look at the force analysis.

In addition to doing a lot of questions, it is a lot of questions.

The college entrance examination is imminent, if you have a poor foundation in physics but want to improve your score quickly, you can take the following measures:

1.Get to the point. The scope of physics is very wide, and it is necessary to grasp the key points and hot spots of the college entrance examination to review. Pay attention to the memorization and understanding of theories and formulas, focus on mastering core concepts and important laws, and do not spend too much time on complex derivation.

2.Do the main topic. Only by doing questions can you truly test your theoretical knowledge and problem-solving skills, and find out the question types and difficulties of the college entrance examination for continuous practice. When doing the questions, you should understand the meaning of the questions, learn to choose the correct formulas and methods, and be proficient in arithmetic skills.

3.Error correction and summarization. It is inevitable that mistakes will occur in the question, so it is necessary to find the cause of the error and correct it in time. At the same time, it is necessary to summarize the important knowledge points, common formulas and problem-solving skills and methods of each chapter, and understand them in depth rather than memorizing them.

4.Targeted review. Students' weak points in physics may be different, so they should focus on reviewing chapters or question types that they don't know well and are not very proficient in.

For example, some students are proficient in theory but poor in problem-solving skills, so they should focus on practice; Some formulas are not very proficient, so it is necessary to increase the memory and application of formulas.

5.Increase the number of times you practice boredom. Reduce the difficulty and start with the basics. Do more questions under time-limited conditions, get used to the speed and rhythm of problem solving, and experience the feeling of real exams. In addition to doing questions, you can use appropriate **** or simulated demonstrations to increase understanding.

6.Supplementary knowledge and review materials. If there are knowledge points that you don't understand or don't know at all, you should consult other information in time to supplement them. And you should review the textbook repeatedly so that you are in a state of proficiency in all the knowledge points.

7.Stay positive. Improving your physics grades requires effort, determination and perseverance.

Don't give up easily because of a poor foundation, always maintain a positive and confident attitude. I believe that through hard work, you can also get a more ideal score improvement effect in a limited time and achieve your target results.

The above 7 points are suggestions for quickly improving physics scores. Extensive practice, targeted revision, elimination of differences, and proficiency in knowledge are all keys. I believe that perseverance will definitely be effective. Finally, I wish you success in the college entrance examination!

There are less than 30 days left before the college entrance examination, and for students with poor physics scores, it is possible to improve their scores quickly, but it requires a certain amount of effort and strategy. Here are some suggestions that may be useful:

Master the basic knowledge: First of all, you need to have a solid grasp of the basic knowledge, which includes learning the basic concepts, formulas, theorems, etc. of physics. If you don't have a solid foundation in physics, it will be more difficult to improve your grades.

Brushing questions: Brushing questions is one of the effective ways to improve your physics scores. You can choose some classic physics questions, and cover all the knowledge points as much as possible, and practice repeatedly to find out the mistakes, find out the problems, and constantly summarize.

Focused training: Focus your attention on a few key knowledge points and practice a lot in a short period of time. This will help you grasp these knowledge points faster, and improve your speed and accuracy in solving problems.

Find the right way to learn: Different people have different learning methods, and you need to find a learning method that works for you. If you are not doing well in physics because of improper study methods, then you can try some new study methods, such as reading textbooks and taking notes.

Ask for help: If you're having trouble or can't solve it, ask for help. You can seek help from teachers, classmates, parents, or other professionals who may be able to give you some helpful advice or provide some effective solutions.

Finally, it is important to note that improving your physics scores requires long-term effort and perseverance. Don't expect significant progress in a short period of time, you need to be patient and persevering, and keep learning and training. Come on!

It's been 60 days. The last time to make up for the shortcomings. Based on the situation you described, I think you have a poor understanding of the basic concepts.

You can quickly identify the type of problem and memorize the corresponding formula. Description: You are a hard-working classmate, and you have tried to summarize and summarize by yourself, and you belong to the category that will learn, so you don't need to worry.

Because the difficulty of thinking and calculation in the physics test of the college entrance examination is very limited, which is different from mathematics, there may be more complex analysis on sports questions, such as the combination of electromagnetism and motion. Almost all of them are testing the "understanding" of concepts and formulas.

Two suggestions: 1. I highly recommend it, but since it is only 60 days, it is risky. The key to reading the book from the beginning, concepts, definitions and examples used to describe concepts and definitions is to think about the physical process clearly, try to simulate the physical situation in your mind, and try to analyze the meaning of each physical quantity in the formula.

It takes about 3 weeks and is risky.

2. Find a teacher to ask for a lesson plan. Look at the explanation of definitions, as well as the scheme of the example problem explanation of the design. This method is relatively fast.

I suggest not to enter the sea of questions until you find the root cause, because the direction is not clear, and the more you go, the more dizzy you become. You don't feel like you're doing too little on a question.

For example, the problem of conservation of energy and the relationship between positive and negative signs is that the concept is not understood thoroughly and the physical process is not clarified. Formulas are dead, physics and mathematics are different, physics has no identity. The external conditions of each physical quantity may cause it to be used differently in the formula.

For example: a helicopter hovering in the air. How to analyze?

Can it be conserved with momentum? You can try to analyze it in your head. Conservation of Momentum:

The system is not subjected to external forces. How do you understand this? Do we think it's free fall?

No! Air does not do free fall, so the system composed of air and *** does not apply to the conservation of momentum!

As for the work done by the external force, the formula: w=fs Here is not only the 5 symbols w f s = *, but also the direction of + -s and f is the key to determine itself + - and the key to w +.

Like such a formula, the concept to eat. Trust you to do it.

You are asking the right person, I just helped a student last year at this time, more than a month, from more than 60 points to more than 90 points in the college entrance examination, although it is not very high, it is already a big breakthrough for her. I think it's time to read the book "thin", a lot of knowledge points are strung together, and each knowledge point is found to be related to the parts and similarities and differences through analogy and other methods, so that you can be more clear about how to use them, as for the question type is not very good at doing, I estimate that you may only vaguely know what method to use to solve many questions, do not know how to write, how to analyze the process state, etc., it should be said that you may have a lack of modeling ability, you can try to draw more sketches including process diagrams, force diagrams, etc., abstract into concrete, It can help you form ideas, and there is a teacher who understands a question after class, and re-solve it after class until you get the correct answer.

Physics is actually very easy to learn, if you want to learn physics well, you need the most basic formulas, so it is recommended that you sort out all the formulas in high school first, and then memorize them, especially some easily mixed formulas must be memorized, and there are some definitions, which is very useful for answering questions, if it is some difficult calculation questions, you can generally go through the method of reverse thinking from the requirements step by step, and the problem will become very easy!

If you can, it is recommended to buy a practice book to do, because after all, it is still a test-taking exam, and the method is not as good as the tactics of the sea of questions.

Classmates,Don't ask for much,It's really difficult to raise your physics very high in the shortest possible time.,What you should do is to give up part of the physics questions directly.,Focus on a part.,Let this part get a full score.,The rest of the part is written according to your memory.,This part of the main attack.,You find dozens of sets of this kind of questions.,Do it carefully.,And then summarize according to the question type.,Because you have a good foundation.,It should be no problem.。。 Remember not to ask for more, physics is a discipline that is taboo

I have a method you can try: you get the physics paper, do the basic questions and intermediate questions, make sure that the basic questions are as correct as possible, the medium questions are 70%-80%, and the difficult questions do its small questions, and skip the rest directly, so that you should have a little time to check, then see the correctness of the questions you have to get right before. If you want to improve the most effective way is to use the question sea tactics, for this topic that I am really not good at, the effect of using the question sea tactics is still good.

Do a lot of questions, do it with your heart, and after you finish it, you should study the problem-solving methods and problem-solving ideas with your heart, the key is the word "heart", and I will say the general "heart".

The key is to eat the textbook thoroughly, but when the college entrance examination is approaching, you don't think you will have the heart to read the textbook, in fact, it is still effective to look at the textbook after completing a set of questions. Do more college entrance examination questions in recent years, sort out the approximate test points, and summarize important formulas. In the exam room, if you really don't know anything, write the formula, write all the formulas that may be used, and don't write the results.

Physics is a test of thinking, sometimes it requires a change of perspective, and it may also require the use of life experience. Learning physics depends on understanding, not in a hurry.

Now you find some physics problems, there is a process of solving the problem, see how he answers the question: that is, how to write each theorem in the answer, when analyzing the force, analyze each force, and then write out the theorems separately, and finally superimpose the forces! Remember to read all the experiments you reviewed comprehensively, you must remember the circuit diagram, electricity is very important, and the big timer mainly depends on how to calculate the acceleration" The last answer question is usually the acceleration of electric ions qu=1 2mv squared, in the deflection power plant, and finally Lorentz, write out what theorem is obtained, and finally write after the result, remember the result, because the exam is scored step by step.

1. Find a tutor. To be experienced, it is required to be able to concentrate on the knowledge and solutions of college entrance examination type questions.

2. Self-study. This is to take the 5-year college entrance examination questions first, then do the 5-year real questions, and then understand the knowledge points and solution methods of the real questions.

3 It depends on luck.

In fact, high school physics is very simple, the key is to establish a good physical model, and the physical model can be said that there will be no more than 30 physical models in the entire high school, and the better your understanding of the model, the fewer physical models, because some models are thoroughly understood, in fact, they are the same as many models. Here's an example:

A smooth inside, the intercepted ball is placed on the table, and the radius of the ball is 2mA small ball swings from side to side in the vertical plane inside the ball, and the horizontal range of the swing is, ask you how long it takes for the ball to go from one end to the other?

This question is typical, many people have done it, and when they first came into contact with it, most people said that they couldn't solve it or that the conditions were not enough. If you only know that you can solve this problem with t=s v, because the motion of the ball is very complicated, you can't use that formula, so what the question says is actually misleading. Pay attention to the title:

The radius of the ball is 2m, and the swing range is only, and there is also the concave surface of the ball, isn't this very similar to the movement of a single pendulum? Whereas, the single pendulum has a temporality - period. So the problem is easy to solve.

Obviously, if you are familiar with the model of the single pendulum, you can think of it at once.

There are many models: such as:

Earth Satellite Model: As soon as we talk about this, we must be able to relate to the three formulas of cosmic velocity, angular velocity, linear velocity, acceleration, and period. This model is the same as a car crossing a bridge and a train corner, so you have to think about centripetal force and so on.

If you can unconsciously think about these questions, the chapter on gravity is pretty much the same.

Oscillator model: This is to think of the magnitude and direction of acceleration, velocity, and restoring force at the equilibrium position. The mechanical wave model, the single pendulum model, is also based on this model. Wait a minute.

Some of them can't remember, it's been several years since they graduated, and it's definitely helpful to explore it on their own, and I can remember so much now because I remember the model very clearly, and because it's easy to remember.

The model not only condenses the knowledge points with high precision, but also makes us remember the problems we have done very deeply, which is unforgettable!
