Read the textbook first, then read the reference book, and then do the questions until you can do it!
Outsiders have misunderstood the tactics of the sea of questions, the sea of questions is not for you to do repeated questions, and the sea of questions is not for the purpose of doing all the questions and then you can meet them in the exam!! The sea of questions is to train the senses, to train a kind of physical thinking, you will have a feeling when you do more questions, and when you get a physics topic, you will use physical thinking to consider the problem.
The most difficult thing in physics is the process problem, but the easiest is also the process problem, which is the problem of feeling. In fact, each process is a very simple problem.
-
We advocate not engaging in the tactics of the sea of questions, but in fact, we still have to do it. High school physics textbook knowledge is easy to understand, but only textbook knowledge is not enough, because there are many types of questions, there are many traps, which has to rely on more questions to not fill, after doing more questions, the thinking is very open, and the experience will be very rich, so little by little accumulation, physics will become natural.

Textbooks, textbooks are more important things, followed by some necessary reference books, but textbooks can never be separated from, although the above content is simple, but they are all basic

It's best to have a notebook, write down everything you have learned from yourself, and then analyze and deepen each knowledge point.

Here's how to teach yourself high school physics:
1. Consolidation of foundation; 2. Ways of thinking.
Cultivate; 3. Do more questions; 4. About the teacher.
Generally, the skills of explaining physics problems are not as good as those of mathematics, and there are not as many things to remember in physics as in chemistry classes, but there are more difficult to understand in physics than in these two courses, and it will be plausible if you can't figure out the connotation of physical concepts, physical laws, theorems and physical formulas.
Mastering basic physics knowledge is the primary task of high school physics review. The purpose of high school study is for the college entrance examination, and the questions for the college entrance examination are basically from the textbooks, and no matter how the questions are, they can't escape these textbooks.
Therefore, the consolidation of the foundation is to firmly remember the knowledge of the textbook. And if you don't grasp the definition well, you will often get things confused.

Summary. Hello, if you study physics in the first year of high school on your own, it is no problem, can you learn physics in high school by yourself.
Hello, if you study the physics of the first year of high school by yourself, it is no problem, the physics of the first year of high school is simple, you can learn it by yourself, and it will not involve too much knowledge of the college entrance examination.
In the second half of the second year of high school, the knowledge base of the third year of high school can be learned, but the experimental questions and big questions will be much more difficult.
You need to find a teacher to explain, look at the answer by yourself, you will have no clue, many knowledge points are jumping, there is no book on it, so this is divided into grades.
So how do I teach myself?
It is recommended that you buy textbooks first and then go to Bili to find courses.
There are recorded lessons from the teacher, and then you can follow along.
All right. Then do the teacher's question, because there are some questions, you may not know, you can ask the teacher the idea of this question.
It's just that I studied in a vocational high school, and the teacher didn't speak well, so I needed to learn a lot of knowledge by myself.
If it is said that the teacher of Pugao teaches you physics, what you teach is the most basic, just master these things.
Because you don't have to master too difficult knowledge points, the focus of the college entrance examination is also different.
Can you recommend a few books for my rabbit that you can read?
What is the teaching aid of vocational high school?
Isn't it just the teaching assistant physics of the general high school.
I took the general college entrance examination.
Textbook help, 5 years of college entrance examination, 3 years of simulation, knowledge list, 38 sets of Tianli, gold exam papers.
These are all right, I graduated from Hengshui No. 2 Middle School, and they are basically the same volumes as Hengshui, and they are all used in these, haha.

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.

How to learn high school physics well.
1. Read the textbook repeatedly. This step is crucial, and almost all top students have experienced it. Textbooks are the best teachers.
Many students will say, "The textbook is so simple, and the exam is so difficult, is it useful to see it?" "That's not right.
In fact, as far as I know, anyone who has a bad or mediocre score in physics is not a solid basic knowledge. They think they have learned well, but in fact they do not understand the most basic concepts and theorems. If you don't believe it, you can open the textbook table of contents and carefully review the relevant content section by section, and then you will understand what you don't understand.
For a physical concept, you have to understand it at a deep level. Let's say two small balls collide, what can you think of from that? What's wrong with momentum?
What's wrong with energy? You don't have to think about these questions when you have to do the questions. These questions may seem simple, but when you think about it, you can come up with a lot of questions. Moreover, such simple questions are the root of hundreds of millions of exam questions.
2. Do some simple questions. This second step, like the first step, is despised by many. They may think that doing those easy problems lowers their status, or that they are too busy with difficult problems to do the easy ones.
What is a "simple question"?It is those that directly examine basic definitions and theorems, such as exercises in textbooks and slightly more complex questions. The purpose of doing these questions is not to answer the right question, but to understand the question thoroughly and associate something from the simple question.
Some so-called puzzles are actually a combination of several simple problems.
3. Read more sample questions in reference books and do some general questions of medium difficulty. Personally, I like to read the example questions in the reference book the most, because the number of questions is small, and it is typical, and the answers are very standardized. After class, do a few medium topics to practice, the effect is often very good, do not ask for more, a few are enough.
It's still the same old saying, think back to it when you're done.
4. For difficult problems, take a look and do with an attitude of appreciation and playfulness. To be honest, there are no difficult questions in the current science and science exam, at most they are related to the reality of life. And the practical questions are often not too difficult, but the lack of reading the questions intimidates a group of people.
At least 70% of the questions in the comprehensive examination are easy or medium, so for most people, the focus is to lay a good foundation and do a good job in simple and medium questions; Besides, only when these questions are done well can we have the time and ability to do the so-called difficult problems. One more word of caution: the so-called medium difficulty questions are just simple questions that are slightly more complicated.

Rest assured, as long as you have a good book and a smart brain, you can learn everything on your own! If the time is relatively long, you can systematically improve your ability It is recommended to read Professor Cheng Jiafu's mechanics and electromagnetism, which are very good books, if you read 3 hours a day, and the math skills are good, it is no problem to save one, but if the time is not enough, or the math is not good, it is recommended to read the full solution bank, do more exercises, remember, there are many books, as long as you stare at a book to get it through, there will be results! Tell you a little experience, find the essence of everything!

It's not absolutely impossible to learn by yourself, it's just difficult, it's not about ability, it's just that there will always be blind spots in thinking, and many times it takes a little bit from others to suddenly wake up.
High school physics, long live understanding, deep experience.
There is also a physics competition that focuses on dynamics.
-
I think it's better to do it directly. The interpretation of the textbook is too detailed, although it is detailed, many of them are not tested, and it is too late to read them. The above list is basically the key point, and the effect will be seen faster.

It is difficult to learn physics by yourself, and it is difficult to have a teacher to teach it.

Racing is not an easy task, so don't take chances. Now self-study to lay a good foundation, the topic must be done. Self-study textbooks are the main thing, so you should look at the past one by one, don't look at the flowers, and there is also to summarize the previous knowledge of finding rules and contacting them.

"Three Points and One Test" is good, you can buy it and use it. If you really don't understand, you can discuss it with your classmates and teachers, and I'm all of them. It's not under ninety-five. Physics is about studying and thinking.

Circuit diagram analysis is easy to do.
Label all nodes with abcd....Then mark the two points with wires connected with the same letter, that is, the equipotential point, and then draw the circuit diagram again.
The resistance experienced by the bullet when it enters A is A, the interaction force with the bullet. And the time is extremely short, so the bullet, a momentum is conserved. >>>More
1. Learn mathematics well, mathematics is the language of physics. >>>More
Hello landlord, it may be two, because when the force f in the upper right direction, and then the pull force in the vertical direction = mg, the pressure of the object on the ground is zero, so the object is not supported by the force, only by gravity and tension, if there are any questions, welcome to ask, hope! Thank you!
The support force is the reaction force of the pressure of the force object to the force object, its work is only related to the displacement of the force object in the direction of the force, the work done by the support force is only the work done to overcome the pressure, and the mechanical energy is the sum of the gravitational potential energy and the kinetic energy, and the two kinds of work are not necessarily related, for example, on the conveyor belt, the support force does not do the work, but the friction force does the work, so that the gravitational potential energy of the object increases, so that the mechanical energy increases (the object is in a stationary state before and after the work, that is, the kinetic energy change is zero), and on the vertical elevator, The work done by the supporting force is equal to the amount of change in the potential energy of gravity, i.e., the amount of change in mechanical energy (the object is also at rest before and after the work is done), therefore, there is no necessary connection between the two.
