How can I learn physics well in junior high school? 5

Junior high school physics is relatively simple, as long as you understand the formulas and are familiar with the experiments.

Physics multiple-choice questions, some of which are more basic and directly based on the original sentences in the textbook, and an impression of the familiar textbook is similar (you will naturally remember it if you take more exams). For some computational experiments, as long as you remember the turning point explained by the teacher in class, it is almost the same, because junior high school physics is constantly repeating the questions, and you can't test anything new.

Please refer to the multiple-choice questions above for fill-in-the-blank questions.

The experimental questions should be more about the circuit diagram, buoyancy and kinetic energy, take a look at it more, and be familiar with it.

Calculation questions account for a large number of points, and the most important thing is to understand and use formulas, for example, the part of the formula for electricity is converted from a few basic formulas, as long as you understand the basic formulas, even if you can't remember the others, you can also make it yourself.

The most important thing is to do the questions carefully, and listen to the teacher's explanation if you don't know how to do it.

That's probably it, I wish you success in your studies.

To learn a subject well, you need to cultivate your interest in this area. You can explain some phenomena in life through what you have learned in physics, and you will feel a sense of accomplishment. This can boost interest in physics.

Pay attention to the derivation of the formula, don't memorize, when you understand the derivation of the formula and you have a basic grasp of the use of the formula. When you forget the formula, you can also deduce it yourself. And the most important thing is to think carefully, to be rigorous and detail-oriented....

If you have memorized all the formulas and laws, you must have a certain ability to observe, analyze, and understand.

If you can do the above, you can score at least 90 points in the exam.

Junior high school physics is very simple, it is enough to listen carefully to the lectures and write homework carefully.

To learn junior high school physics well, you need to establish a solid basic knowledge of collocation, understand the principles of physics, do more experiments and demonstrations, learn to use mathematics, practice deliberately, and solve problems.

1. Establish a solid foundation: Junior high school physics is built on some basic concepts and laws. The first thing to do is to ensure the understanding and memorization of basic concepts such as force, energy, electric current, etc.

2. Understand the principles of physics: Physics is a theoretical science, and understanding the principles and laws in it is very important to learn physics well. Read textbooks, pay attention to understanding the concepts and derivation processes behind physical principles, think and ask questions, and explore the essence of the problem.

If you get stuck, you can ask for help from teachers, classmates, or other reliable resources.

3. Do more experiments and demonstrations: Physics is an experimental science, through experiments and demonstrations, you can intuitively observe and verify the principles of physics. Participate in laboratory courses, operate experimental equipment, observe experimental phenomena, and analyze data and results.

4. Learn to use mathematics: Mathematics is an important tool in physics, and many physical concepts can be described and calculated through mathematical methods. Learning middle school math, especially algebra and geometry, helps to better understand and solve physics problems.

Learn to convert physics problems into mathematical expressions, perform calculations and analyses.

5. Deliberate practice and problem solving: Physics learning needs to consolidate knowledge and improve ability through practice and problem solving. Do more physics problems, including multiple-choice, calculation and application problems, so that you can be familiar with the types of problems and how to solve them.

Through practice, you can improve your ability to analyze and solve problems, and master common physical calculation and derivation methods.

The Significance of Middle School Physics.

1. Cultivate the ability to think scientifically and analyze problems: Learning junior high school physics can cultivate students' scientific thinking and ability to analyze problems. Physics learning focuses on the cultivation of logical thinking, reasoning ability and problem-solving ability, and through learning physical principles and the analysis of phenomena, students can develop the ability to find problems, explore solutions and evaluate results.

2. Improving the application of mathematics and computing can cultivate the source of learning: Physics is closely related to mathematics, and for junior high school students, learning physics can improve their mathematical application and computing ability. Computational problems in physics involve mathematical knowledge such as algebra, geometry, and arithmetic, and through the study of physics, students can better understand the application of mathematical knowledge and how to solve problems.

3. Cultivating experimental and observational skills: Physics learning emphasizes experimentation and observation, and through hands-on participation in experiments and observation of physical phenomena, students can develop experimental design, data analysis and observation skills. This hands-on learning method helps students discover scientific knowledge and the laws of phenomena, and improves their experimental skills and scientific research literacy.

Physics in the second year of junior high school is actually very simple, you just need to memorize the concept and understand it, do more similar exercises, you can listen carefully in class, and take notes, digest and absorb the knowledge immediately after class, ask the teacher if you don't understand, and do more extracurricular homework to consolidate knowledge, and do experiments after going home, in order to learn physics well.

1. Read the physics book carefully, preview before class, record the questions that you don't understand, know what to do, and ask a few more questions about the things around you. If you don't know, you can find the answer in the book.

2. When you are in class, listen carefully to the teacher's explanation, so that you can improve one step on the basis of your preview, and review after class to make the questions you don't understand clear.

3.If you really can't do it, you can ask your teachers and classmates.

Read more reference books and learn the techniques inside. If you see a question that you don't understand, circle it and wait until the next day to ask the teacher together, and then you will find that you can learn a lot.

First of all, you should listen carefully and take notes on the key points of the teacher's lecture and your doubts about the knowledge points.

Secondly, we should often review the knowledge that the teacher has said, if you have enough time, it is best to do pre-class preview and review after class, this so-called review of the old and learn the new.

Third, we should be good at using our brains, ask questions that we don't understand in time, don't wait for today's things tomorrow, and the fourth experimental class can deepen our understanding of textbook knowledge, and we should be diligent and think more Finally, and most importantly, cultivate an interest in learning physics, and the above questions are not a problem.

You must listen carefully in class, you must do the exercises when you go back, and if you don't understand it, you must ask, and the physical formulas are very cumbersome, so you must memorize and understand them, and you must skillfully transform them into each other I think you will be able to learn it well Come on
