How to bring up physics in the third year of high school

1. First of all, read the textbook carefully, you must remember what you should remember, and you must understand the part that you understand, this is the foundation.

2 If you have a reference book, I suggest that you do a good job of the example problems in the reference book, do one and then compare them to see what is different from the reference book, and pay attention to thinking in this process.

3. Start to do small questions, pay attention to small questions, big questions can not be analyzed at once without foundation, and there is a frustration in confidence, it is best to figure it out, pay attention to grasp the physical situation, this and important, it is very useful for the analysis of big questions in the future.

4 If you have completed the above three steps, it is recommended to start working on big questions, not too much but more and more precisely, and pay attention to scenario analysis.

That's it, I caught up in the last three months of my senior year of high school, and I was the first in the whole school.

Figure out the concept, don't ask too many questions, but make sure that every question is clear.

I am a college student, and I have made up for physics and chemistry for several high school students after the college entrance examination.

Physics is a big piece of everything, and it is necessary to firmly grasp the focus of each piece of content; For example: mechanics. The most common thing in mechanics is force analysis, and the classic examples in it must be understood thoroughly.

For example: a, there is a rough slope on a horizontally smooth plane, and a rough block of ground is placed on the slope, and some conditions are known to analyze the force or motion of each part. Mechanics should always grasp the force analysis.

Then the mechanics will be well applied to kinematics and electromagnetism.

In short, to sort out each step, it is necessary to go deeper step by step. Usually the most basic cohesion is the difficulty. Physics is like that. The last question of the college entrance examination is comprehensive, which requires mechanics, kinematics, and electromagnetism. Remember that the most basic cohesion is the difficulty.

Personally, I'm okay.

Physics study: I think you can start with the following points.

First of all, you have to have faith in yourself.

Even if your physics is not good right now, you have to always believe in something. No matter how strong others are, they can't score 101 points, they are all ordinary people. Could it be that they are the reincarnation of geniuses?

If they can learn well, can't I learn well? As human beings, you have to believe that you can learn better than them through hard work. You still have a lot of room for improvement in physics, so learning physics well can also improve your overall score (I'm sure you know it).

The second is to develop an interest in physics.

Interest is the key to learning physics well. If you are interested, you will be motivated to take the initiative to learn, rather than passively accepting. I can play the ...... I like to do physics problems in my heartHehe, in fact, there are a lot of classic physics problems that are very tasteful.

For example, the ball collision problem, the slope spring problem, and so on.

In addition, the learning method is also important.

a. Try to find your own shortcomings after each exam, is it careless to deduct points? Then pay more attention in the future, and be careful when doing questions. Is it because the knowledge points are not in place?

Then take a closer look at the knowledge points that you don't understand, and when you need something, you can learn it, and the absorption ability is very strong. Is it the time to get it right? Then usually when you do the questions, you will get more time than you can get down.

Or is it too slow? This is the level of proficiency in mastering knowledge points! You have to think about these carefully, don't throw the test papers aside as soon as the exam is over, and learn to summarize.

b. Be with classmates ****. Sometimes there are many solutions to a physics problem, and in the process, you can not only know what you are lacking, but also may hear some particularly novel solutions from their mouths....

c. Prepare a thick diary, and encounter the questions you have done wrong, classic questions, novel questions...You can copy it down, if you don't have time, you can cut off the small piece of paper and paste it on the diary with solid glue (o(o, that's how I got it, it's very effective), pay attention to not do it if you don't get it, you have to look at it more often......

d. The question is sea rafting, and the summary is the shore.

Sometimes don't simply think that you have mastered the knowledge points here after doing how many questions, this is a lie to yourself. Keep in mind that it is impossible to fully grasp every knowledge point, only whether the proficiency level is higher than others. When you encounter a good problem, you can think horizontally and vertically, or whether there is a better and simpler way ......

Don't be fooled by exams. The test score does not mean anything, don't be complacent if you do well in the test, and be sad if you do badly....If you take good grades as the motivation to study, you will not be able to really develop an interest in physics, remember, take the exam as an opportunity to learn about physics some time before the test, and do not be happy with the results, and do not be sad about ......the results

f. Finally, remember to read more textbooks. After all, everything is changing...

I will tell you about my method of learning physics from my personal experience, hoping to help you, but after all, everyone has their own set of learning methods, and I am just here to give you a little reference .........

First of all, it is very important to be familiar with the textbook, you must read the book repeatedly, do some basic questions on the basis of understanding, and gradually look at the difficult problems.

I won the first prize in the provincial physics competition in my sophomore year of high school (62 students), and although I am a sophomore, I think I am still qualified to give you some advice! I'll just talk about some of my previous learning experiences.

First of all, physics is a science subject, and the formulas must not be memorized by rote. I remember that I never seemed to memorize formulas, but I always memorized them by doing problems and then going back to them to strengthen my memorization of formulas.

Then, it is better to look at the ten questions than to do one yourself. It's better to read less questions than to skip them when you think you can do them. The hidden test points of many questions are discovered step by step in the process of doing the questions.

High School Physics, Heat, Electricity, Light, Primordial. Mechanics is definitely the focus of the points. There are many test points in mechanics, which should be strengthened.

Interest is the best teacher. Physics is an interesting subject, and a practical subject is a great subject. We should pay more attention to the physical imagination in life and stimulate interest in physics.

Only by loving physics can you learn physics well. I often bring what I have learned to real life, such as the single-sided translucent glass in life, the ripples in the water, and the recoil involved in the rocket launch on TV.

Anyway, I think I can learn physics well because I like it. Remember to learn physics well for a lifetime.

Do more, think more, ask more, persevere.

In fact, physics is very simple, first of all, don't do it blindly, if you are a high school student, those monthly exams, midterm exams, final exams, the question types of the exam are turned out one by one, and you can take notes to summarize what question types have been examined. Copy a question of the same question type into a notebook, and then record it, and mark the word "positive" next to this question type several times.

If your foundation is not bad, then you should not have summarized it well, the night before each exam or at noon, you are looking at the types of questions you have summarized, so that you can understand it! It's not easy to panic when you take the exam!

If you want to do typical topics, learn to draw inferences, think more than do more questions, you teachers... No need to go to the birds of theirs!

I think you should analyze the reason why you are poor, rather than just knowing that the effort is fruitless:

Can you pass the usual book knowledge points?

Can you understand the summary of the review book?

Can I pass the assignment?

Do you understand all the exercises?

Or did you make a mistake on the exam**?

Careless? Not thinking deeply?

Still is. You should be clearer so that others can give you the best experience.
