How to learn mechanics in high school physics?

1. I finished the compulsory 1 and 2 after the high school entrance examination. It's not just about reading books, it's about asking questions. The knowledge in books is easy to understand or memorize, but it is not very easy to start the questions.

If you have a poor foundation, you can do a full explanation of this textbook, read each of the above points of attention and example questions, and at the same time make a good summary by yourself. (Note that it's not the knowledge points that are summarized, but the methods or fallible traps.)

2. Physics is actually just solving by using formulas and adding constraints to the problem. The idea of equations in mathematics can understand the problem solving ideas at a deeper level. For example, a model has many variables, such as the velocity and acceleration of an object, and n equations must be required to solve n variables.

In a two-dimensional model, orthogonal decomposition can be considered for the equations.

3. If you think your comprehension ability is not bad, you can take a look at the college textbooks, although there are some calculus in them, but the essence is the same as the books, reading the university textbooks can help you better understand the formula and find the solution ideas.

4. You can think of several ways to do the questions in ordinary times. Although the format requires that you write it in one way, you can use other methods to check whether the answer is right or wrong.

The above is what my other people are talking about and should be useful to you as well.

Mechanics is the best to learn, he is not abstract. After reading the questions, you can think about the specific movement process in your mind, and then use the formula to express the specific movement and then calculate. Hope.

The teacher reads the book before class and circles what he doesn't understand. When the teacher talks about this point in class, you must concentrate on it. If you don't understand it, ask the teacher immediately after class, and it's important to have a set of mistakes. I have it in almost every subject. Hope.

Because one and two are subject to an F and to produce acceleration, the length is less than 12, but 4 is also subject to friction, so the spring is subjected to a frictional force. Therefore 4 3f = kl so the two springs are subjected to a force of 10n respectively.

Both springs are stressed in the direction of the upward direction.

So the ball is subjected to an upward force of 20n.

Its gravity is 10n, so it has an external force upward, so the tripod must have an elastic force on it.

Basic knowledge is very important, solve the problem standard, think more and practice more, and find your own thinking habits.

Do more questions, don't memorize formulas, and learn to use them. Look for more types of questions.

First of all, you have to be interested in him, if you study because of the college entrance examination, you can only memorize the physical formula, understand the meaning of each letter, and what problems this formula solves. In a word, learn physics well, read it well, and understand the textbook. Do more questions and practice more.

Students with good grades in physics tend to be.

1. Playful, love sports (classical mechanics, personal experience of kinematics) 2, curiosity, inquisitive (always want to know why).

3. Be able to study research, learn from play, learn from experiments, and take the initiative to summarize from life phenomena.

4. Concepts are not rote memorization, he may not express them word for word, but the meaning of the expression is something that he has already understood. Therefore, physical concepts should emphasize the use of one's own language to clearly express a certain physical concept.

If you can do the above points, you can score more than 90% in high school physics without a teacher.

All I can say is this: first read the book, and then practice a lot of physics. If you practice more, you will naturally become a master.

The most basic thing is to grasp the principle and combine it with the real thing.

Physics: Mainly the understanding of concepts and formulas. For concepts, you must grasp them well, and doing more multiple-choice questions will help you grasp the understanding of concepts.

But you must take each question seriously and understand each option when you do it. Calculation questions are accurate formulas. So be especially aware of the meaning of the formula.

Practice more, the questions are actually many similar.

In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method.

Good luck with your studies!

Read more books, have your own understanding of this physical system, memorize typical examples, and learn the general methods of analyzing physical processes.

Ask your teacher. He knows a little bit about your situation, and only when he is clear about your current situation can he know where you should strengthen.

"Asimov's Latest Scientific Guide", "The Evolution of World Science", "The Physical World of Ordinary People", "We Live in the Magnetic World: Magnetism and Applications of Matter", "Alien Physics", "The Principle of Everything". Each of the above books does not require you to read, and it is good to have some comprehension, which can help you better understand the content, methods and meaning of physics.

1. Don't be in a hurry, the more anxious you are, the more you can't, and you must be confident that you can learn well;

2. Don't just listen in class, think more, keep up with the teacher's rhythm, think in combination with the preview, truly understand what you have learned, and ask questions in time if you don't understand;

3. Practice on the basis of reviewing and understanding knowledge in a timely and independent manner after class, find that you do not understand, and solve it in time;

4. The problems of the day are solved on the same day, and the knowledge system is sorted out once a week.

Because high school knowledge is a complete system, it is often difficult to understand when you only learn a part of it, and when you integrate it, you will have a sudden feeling of enlightenment.

Learn physics well and persistently!!

Read the principle in one sitting, then close your eyes and think like this, and you're done.

Because reality is not like martial arts films, there is such a thing as passing on the gong, and it is impossible for knowledge to become yours all at once from other people's minds, countless predecessors experience summary learning is a long process, and it is impossible to dig a well with a hoe, but as long as you learn one thing with your heart, there is nothing that can't be done, the key depends on your mentality, whether you are always concerned about such and such things, left and right, when you don't have the confidence to persevere, watch more inspirational movies and television, and look at the biographies of successful personnel, People need to be constantly motivated, I hope you can learn in a down-to-earth manner, ask a few more whys, and you will definitely learn well.

Patiently do more questions, it doesn't matter if you can't, ask the teacher, do more and then summarize the method, and finally the highest state is to summarize the thoughts.

I am a high school graduate student, in high school I was qualified for the physics competition, I think high school physics must first learn the essence of the knowledge, at the beginning of high school must seriously learn the force analysis, mechanics is the foundation of the whole high school physics, it must be quite difficult to start learning, but you must do it with a certain amount of effort, and you must communicate with the teacher often, in the process of communicating with the teacher, you will gain a lot, remember, Learning mechanics is the foundation of learning high school physics, mechanics is the skeleton of high school physics, in addition, summarize your common mistakes, don't always wrestle in one place, believe you, come on!

Pay attention to the basics, flip through the textbooks more, and you will find that many things that you find difficult in the exam are answered in the textbooks, and the more you read the textbooks, the more interesting they become.

Every time I look at it, I get something new.

Don't be greedy for too many questions, do a good job of summarizing and summarizing the question types.

2 simultaneous exercise books, 10 sets of test papers. Enough is enough. After doing it all, review it once in a while, absolutely OK

And everybody said, "I don't know how to study physics."

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way: a vacuum is really empty, there is nothing.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.
