I am a junior high school student and have no confidence in physics

Hehe, I just graduated from junior high school, and my second year of junior high school physics is also rubbish, and even the level of junior high school physics is very bad (it's the first semester). When you arrive at the end of the second semester, you will enter the general review, and the course has been finished in advance! Entered the era of the sea of questions,.

At this time, I found that my physics had improved, but in fact, I didn't do enough questions

Tell me the trick and buy a workbook with explanations. While reading the answers, thinking along with them, the other is to do more and ask more questions

You are a very self-motivated person. It's normal to have this kind of thinking, because there are too many questions that others won't do. And is it true that the more questions you don't know, the more you want to do more? It's okay, it's not a negative thought, it's just unskilled. It would be nice to listen too much!!

Don't be negative, have confidence in yourself, just the third year of junior high school, hello has a lot of hope to learn well, conditions:

1. It's very old-fashioned, you have to really listen carefully in class, and you won't just ask, until you understand.

2. Do the problem yourself, don't copy it, you can't do one, cultivate your own feeling for the problem, physics is like this, as long as you have a feeling, it is much simpler than mathematics.

3. Cultivate your own physical thinking, that is, observe more of the knowledge you have learned and whether there is any existence around you, and use the things around you to analyze.

4. Do more practice questions outside of class, even if you look at it, and be patient to summarize every week, just do a summary for 1 hour a week.

This is my learning method. I'm from Tianjin, but I have a soft spot for physics and I hope you succeed.

The landlord doesn't have to be so helpless, in fact, as long as you train more, practice solid basic skills, and then cultivate the corresponding psychology of doing questions, you don't have to think about the third year of physics too terrible, as long as you are willing to learn, it is still easy to get a high score!

Give you a good way, if you use it still bad you come and kill me.

The premise is that there must be a physics hobby MM in your class.

Then you confess to her, you will get rich after this level, love the house and Wu, you will be good at physics because of her, study physics with her, and the two of you will be fine in the classroom to study and study, just don't do good things.

Do more questions, 1 type of question, 10 times if you want to get it wrong.

Don't go to the high school entrance examination.

After reading the Jinghe Temple, I know that you may not be using the human teaching version. What I want to tell you is that electricity is really not that hard. I just finished junior high school with electricity.

You have to believe that you can learn well. Listen carefully in class and read your notes carefully. If there are exercises that you are not familiar with or do not know, after understanding, you can summarize the practice of such questions in your own words, and find more questions to practice.

I'm also going to the third year of junior high school, and physics is not much, the teacher said that the concept must be memorized like English, and it should be more connected to the reality of life, in fact, the physics of the second year of junior high school is nothing, the most important thing is the electricity of the third year of junior high school, come on!

Knowledge is the best in life, and it is very helpful to learn to pay more attention to observation in life, especially physics.

Find some topics to do by yourself, find your weak areas, don't do much, understand them completely, and don't be afraid of wasting time.

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.

I am a high school physics teacher, and the problem you mentioned is a common problem for high school students, and the solution to this problem is: read the textbook 2-3 times after each class, find out two or three things that you don't understand, and then try to understand it (you can ask the teacher); Find a topic related to the content of this lesson, try to solve it yourself, if you don't have the idea to read the problem, read the book, because this kind of training often corresponds to the knowledge points of the new course, and only by solving it yourself, can you appreciate the essence of physics knowledge. Do the questions thoroughly, rather do less, or even don't do it or guess blindly in order to complete the homework, if you guess blindly, it can only consolidate your wrong thinking over and over again.

The more questions you do, the worse your grades will be.

The thinking is not continuous, and it may be that the basic knowledge is not solid. Do more pre-study and review, and you have to have confidence in yourself, you yourself have no confidence in yourself, and the paper tiger of physics is even more arrogant!

Choose a textbook like Complete Interpretation that has a lot of knowledge to explain. Knowledge from books is not enough and must be supplemented with the necessary reference books. In addition, practice is unavoidable, and you must review the knowledge points that you can't do in time, feel more important and do wrong.

Physics in middle school is very basic, so you must pay attention to the basic skills, thoroughly understand the textbook, and do some questions to consolidate it after each chapter and section, and it must be appropriate, too much or too little is not appropriate!

First of all, you don't have to be nervous. If you want to take the general high school exam, as long as you work hard, this can be achieved.

Secondly, it is said that hard work is not done just by thinking about it and shouting a word. It's about hard work. First, we must restrain ourselves, devote ourselves to studying, and dare not have the slightest distraction.

Second, it is necessary to make breakthroughs in key areas. Thinking and history are open-booked, you must listen carefully to the teacher, prepare the materials, do a good job of various labels, so that you can find them at once, and carefully ask the teacher and students who study well, and imitate their answering methods, so that these two subjects will be improved. It is necessary to keep the experiment in mind and get the score of the sports standard.

So you're one step further. The third is to make more workbooks for mathematics and English, and the most important thing is that after the teacher corrects it, it should be carefully corrected at the original question and corrected with colored pens, so that it can be seen at a glance before the next exam and will not make a second mistake. That gives you a little more certainty.

Fourth, the remaining courses, too, should keep up and don't let it fall behind.

Third, we should force ourselves to develop good study habits, one is to analyze the papers, which mistakes are not at all, which ones are caused by carelessness, which ones are usually unskilled mistakes, and which ones are too nervous. The second is to grasp the study time, don't get excited to do it until the next two o'clock, and don't do anything when you're lazy. In this way, it is no problem to score more than 400 points, and if you do a good job, it is not impossible to score 500 points.

It is not a dream to go to the next high school. Hope what you have said above helps.

This is not a problem at all. What do you need?

You are already very good, as long as you stick to your goals every day, I believe that you will succeed in the high school entrance examination. Be confident.

The junior high school questions are actually not difficult, and it is not a problem to have a bad foundation, mainly relying on the review of the third year of junior high school and a large number of questions. Moreover, the questions in the high school exam are relatively much simpler than usual, and it is not a problem for people like you to take the high exam.

P.S. Mindset is also very important.

I am also a science student, and I think the best way to learn science is to read the textbook from beginning to end, and after reading it twice, the basic formulas, question types, and chemical molecular formulas are clear to me, so it will be much easier to go up again.

In addition, the content in the textbook will be relatively simple, and it will not seem so troublesome.

And as a parent, be sure to give him enough trust and patience, don't let him feel your anxiety, otherwise he will be very stressed.

I am a student of chemistry and a teacher, mainly because the children are not very interested, and if there is anything that can help with learning, they can leave QQ

In fact, this one is relative. In reality, we are walking, swinging our arms, etc., all the time rubbing. Even if there is no large movement, when we sit, there will be a flow of air, and there will be slight friction

Or when we come into contact with something else, that electricity disappears. To put it simply, this thing exists all the time, but it also disappears all the time.

For example, when you take off your sweater in the winter, there is a spark because it is electrified. And this electricity dissipates with the air, or with your body, or anything around you that can be touched, including air. It's like smell.

And if in an absolutely ideal environment. Suppose, no air, no light, no conductors, absolute vacuum. Electricity is not conducted. Will be there all the time, as you say.

It is ideal to stop rubbing against other objects with it, and it is impossible to achieve. Assuming that it is possible, it will always be electrically apparent.

Electrical neutralization is a steady state in nature, and being charged in the natural environment (without human influence) is a temporary state. Therefore, if there is no human influence, the charged object must return to an uncharged (electrically neutralized) state, and the lost electrons are compensated from the ions in the air, and the ions in the air are thus changed to atoms or molecules. Neutrality is also a fundamental law of nature.

Theoretically, yes. But in reality, the power is constantly being consumed because of contact with the surrounding environment. So a tiny charge will eventually be uncharged.

No, because it doesn't exist in an ideal world, there's no friction, but the reality is that it's also possible for it to rub against other objects, which may lead to more charges on other objects and become uncharged.
