High school physics is really impossible to learn, alas

At this point, you can't follow the usual routine.

I suggest that you start with the physics books in your first year of high school or even junior high school, and whether you have the mind to read it depends on whether you want to learn it or not, and then it is very important that you have a clear understanding of how those formulas come about!! It's easy to say, but it's not a joke that it takes a lot of time to do!! There are a thousand Lin Daiyu for a thousand readers, don't understand a little bit and think you understand everything, after reading the book, you can look at the extension and expansion of the tutorial book [Wang Houxiong] and you will know, and then the point is to solve the examples of different formula synthesis types, which requires you to brush a lot of questions to complete [genius is still rare, be practical].

What I said you can use as a general directory for learning physics, and the specific implementation plan needs you to establish, of course, if you can't put down games, mobile phones, networks, etc., then no matter how good the learning method is for you, it is a bamboo basket for nothing.

The knowledge points must be understood, and the textbook must be thoroughly understood before doing the questions step by step. Don't do the questions blindly, don't think about using the questions to practice the knowledge points, otherwise the confidence will be exhausted, you must pay attention to the knowledge points, not necessarily from the textbook, but you must first understand the knowledge system and know what is going on.

I have come into contact with many high school students, and they are all good in junior high school physics, with a minimum of more than 90 points in a 100-point paper, and even a few people who get a full score in physics in the high school entrance examination. But without exception, almost all of them fell down in high school. Is high school physics really that hard?

What are the basic abilities required of high school physics?

1.Imagination.

I think this is one of the most important basic abilities to learn physics in high school. Of course, it is a rational imagination based on the system of physics, not a wild whim. It's easy to say, but it's really hard to do, and this needs to be cultivated from a young age, not something that can be built up in a few years.

Good physicists have quite a lot of brains. For example, Albert Einstein. The famous theory of relativity was developed with the blessing of his imagination.

Due to the limitations of technical equipment at that time, many reasoning and conjectures could not be verified, and it was not until the progress of science and technology that we got to know this great prophet. Another example, Tesla. He was more unfortunate because his imagination was too ahead of his time.

Internet, PCs, spaceships, ......Today, even our children know this, but a hundred years ago, these things were unacceptable to normal people.

2.Observation.

Good physicists have eyes that can see into the nuances. For example, two leaves, no matter how similar the appearance is, at least the veins and textures of the leaves are different. The same is true for high school physics questions, 99% of the exam questions have been exposed to physical models in ordinary times, and there are only a little nuances.

As a result, the teacher's analysis methods are not correct, and the students in the examination room are not calm.

3.Ability to summarize and summarize.

There are thousands of problems in the world, and improving by doing questions can only have a little effect, but it will definitely not achieve rapid improvement. Be sure to take the time to think about what are the similarities between so many topics you've done? What are the general breakthroughs in this type of topic?

The reason why those enlightened monks can break the world with one or two sentences is because they spend a lot of time thinking about what the nature of the universe is. So, no matter how busy you are, you must take the time to think and summarize.

The second is memory, practical knowledge, and so on. I think these three abilities are the most important, and three years of high school are completely insufficient, so they should be cultivated from the time when they start learning mathematics in elementary school, and they start in junior high school, which is actually a bit late.

These abilities or habits are relatively abstract, and they are not very helpful to the learning of primary and junior high schools, so many parents and teachers do not pay much attention to it, and only when they find out in high school do they think about making up for evil, in fact, it is too late, at least 3 years, the perseverance of ordinary people is completely useless. Parents who hope to read this article must cultivate their children's scientific imagination, keen observation and ability to summarize and induct all things from an early age, which is a valuable asset for their children's life.

Listen carefully to the class and ask the teacher for advice.

The first year of high school is mainly kinematics, and then the basic mechanics, acceleration, velocity, displacement, and force analysis, these physical quantities are not independent of each other, but are related to each other.

If the object is not affected by an external force, it must remain in motion, i.e., it is at rest or in a straight line at a constant speed. If the resultant external force on the object is not zero, the state of motion will naturally change, and acceleration will be generated, the so-called acceleration refers to the speed of the change of the object, which is a vector, and the speed is also a vector, the magnitude of the acceleration reflects the speed of the change, and the direction of the acceleration is the positive or negative of the speed change.

A positive acceleration indicates an increase in velocity, while a negative acceleration indicates a decrease in velocity. The definition of velocity is the amount of change in the displacement of an object per unit of time, and the displacement is also a vector quantity, which is only related to the straight-line distance between the start and end moments of the object, which is different from the distance.

A very important part of high school is the uniform acceleration of linear motion, which is about the relationship between displacement, velocity, and acceleration, and the calculation formula must be kept in mind, as long as the relationship between the three is understood, those formulas are not difficult to remember.

As for the force analysis, this is a basic knowledge point in the study of physics in the first year of high school, and it is also a difficult point, especially for the analysis of the magnitude and direction of the friction force of various Modan wear tests. But in any case, we must grasp one principle, and always analyze according to several principles when conducting force analysis, read more books, think more, and actively ask teachers and classmates for advice if we don't understand.

High school physics is a bit difficult to learn, but it doesn't mean that you can't learn it, as long as you want to learn, you will definitely be able to learn it, the premise is that junior high school physics and mathematics have a good foundation, otherwise it is difficult.

I think it's quite difficult. Because physics is to be calculated, some of them have already been dizzy before they have been calculated.

It is not difficult to learn, master the principles of speed, mechanics, electricity, etc., and memorize the formula carefully, you can get a good score.

This question actually varies from person to person.

If you find it difficult, others will find it not difficult.

The key is that you have to have perseverance, perseverance, and keep accumulating thinking.

Don't get stuck in the doldrums because a question can't be solved.

As well as typical questions, formulas, stereotyped ideas and problem-solving skills, you should be familiar with them.

High school physics is actually a process of accumulation, and if you believe in your own efforts, you will definitely be able to learn well.

What about high school physics? What are some good ways to study?

Now there are many friends, all say that for high school physics is a relatively difficult subject, which makes physics a kind of sore in the hearts of many high school students, in fact, learning high school physics is also very simple, as long as you master good ideas, cultivate your own study habits, let yourself like this subject, in fact, it is relatively simple.

High School Physics Textbook.

1. Learn more, observe more, and think more.

In fact, high school physics is about some theorems of things in nature, these are many things around us that contain these truths, there is physics everywhere in life, for example, every time we take a car, we can see the outside world and the things outside these cars are going backwards, this is the reference in our high school physics, this knowledge point, there is knowledge everywhere in life, you have to experience it with your heart.

As long as we have an eye for discovery, you must look more at the many phenomena in your life, whether it is natural or life, you also have to look at the stars at night, see their changes, you will also find light and heat in physics and some law problems. This knowledge is still present in our lives.

1. Learn to start with theorems.

You have to attach great importance to some theorems and some dead concepts and some laws, but you not only have to remember this knowledge from time to time, you have to learn how to use it, this is the key, smart children are using these formulas and then applying them to their own mistakes, from which to find the problem, you also have to do from a small mistake, you can review a lot of knowledge, it is really a double harvest, which is also the key to whether students can open up in high school physics.

Second, change the incomprehension to be very proficient.

For learning, if you like this subject more, the better you will learn, maybe for various reasons to make you like this subject, maybe because of the teacher, some teachers grasp it tightly, you learn this subject very well, but some students just like this teacher and like this subject, if you change the teacher, you will not learn well, in fact, this is harmful to yourself.

High School Physics Exam Papers.

Read every textbook, read every unit, learn every problem, have key insights and solutions for every exercise in high school physics, maybe they use the same knowledge, as long as you remember a theorem you can do many similar problems.

Uncle Liu's blog: Because I used to be a high school student, are you sure that the most difficult thing in high school is physics? Maybe everyone's way of thinking is different, I personally think high school physics is okay, the most difficult is chemistry, I remember that I used to have a chemistry book in high school, it was different from other chemistry books, he was black and white, yes, it was black and white, that book was really a book for me, chemistry did not pass after the second semester of high school, when I took the science exam, the chemistry part of the multiple-choice questions all relied on Meng, which is the content of the above two books, when I learned organic chemistry, I began to doubt life, Because my previous chemistry grades were still good, but organic chemistry is really not good, there are really many reaction chemical formulas, and the most important thing is that the chemical formula is as long as the book of heaven, and it hurts to read the braincase! I don't know if anyone feels like I feel that high school chemistry is the hardest.

These topics are really the type of people who give up struggling at a glance, that is, organic chemistry makes me lose interest in learning chemistry, no matter what I learn, the interest point is very important, just like the subject you think physics is too difficult, but for me, I think it's really not very difficult, most of high school physics is mechanics, I think mechanics is quite interesting, so I listen to the lecture more attentively when I go to class, so when you think physics is difficult to learn, it shows that you have an aversion to physics, and you don't want to listen to it in class, I want to sleep when I listen to it, just like when I take chemistry class, I can live like a year in chemistry, I can understand and hear clearly in class, but I don't know when I do problems after class, I believe this is also the case when you study physics, haha. Let me give you a little advice:

Cultivate a strong interest in learning physics, interest is one of the driving forces of thinking, interest is a strong and lasting motivation to learn, interest is the potential motivation to learn physics well, just like chasing a girl, if you are not interested in this girl, then you have no starting point for chasing her.

In the classroom, improve the efficiency of listening to lectures, develop the habit of pre-class preparation, it can improve the pertinence of listening to lectures, take good notes, do a good job of review and summary, and the knowledge network of this chapter. The main contents, such as theorems, laws, formulas, basic ideas and methods for solving problems, conventional typical question types, physical models, etc.

To handle the practice questions correctly, the important thing is not to do too many questions, but to have a high efficiency and achieve the goal. The purpose of the questions is to check whether the knowledge and methods have been mastered well.

Learn to review the problem, to be honest, it is very important to review the physics problem, it is best to read the question more than 3 times when you look at the question, look at the process of the question, read it carefully for the first and second times, don't think about the knowledge points, and start thinking about the relevant knowledge points when you read it for the third time.

I hope you can do well in physics!
