Listen carefully to lectures and complete homework.

Physics in the second year of junior high school is not difficult, and it is recommended to have time to prepare for the third year of junior high school.

If you don't know how to ask the teacher, the teacher will praise your ......

How to learn physics well in the second year of junior high schoolUnderstand the place that physics holds

Junior high school physics knowledge is nothing more than the knowledge of five parts: acoustics, optics, thermals, electricity, and mechanics. First have a general understanding, and then you can classify each part of the knowledge, so that you can win the battle of middle school physics. The score of junior high school physics in the high school entrance examination is 70 points, so you can allocate your time and energy by knowing this.

Emphasis is placed on the accumulation of basic knowledge

Junior high school physics is learned from very simple physical phenomena, acoustics, optics, based on the laws summarized by life phenomena, many students think it is simple, do not care, and do not do the learning and accumulation of basic knowledge.

There are many similarities between the study of physics and mathematics in junior high school, and it is necessary to master the basic concepts, laws, etc., and there should be no confusion of concepts in the learning process. Learning basic knowledge is multifaceted, follow the textbook, listen carefully in class, follow the teacher's ideas, and take it seriously whether it is an experimental class or a review class.

Listen attentively

Listen carefully in class and not get distracted. Don't be self-righteous, learn from your teachers and classmates with an open mind. Don't give up listening to the lecture because the teacher is simple, if this situation really happens, it can be regarded as review and consolidation.

Try to be consistent and synchronized with the teacher, and discuss with the teacher after class with different views, and you can't do it yourself, otherwise it will be equivalent to complete self-study.

Suggestions for learning physics in junior high school To clarify the basic concepts of physics in the second year of junior high school, first of all, read the textbook repeatedly. This step is crucial, and almost all top students have this experience, and the textbook is the best teacher.

Secondly, do some simple questions, the purpose of doing these questions is not to calculate the correct answer, but to understand the problem, to associate something from the simple questions, some so-called difficult problems, in fact, are composed of several simple questions.

Then, read more sample questions in reference books and do some general questions of medium difficulty, especially those in reference books, because the number of questions is small, and they are typical, and the answers are also very standardized. After doing it, think back and summarize the rules that suit you.

Let's talk about the basic methods, for example, the holistic method and the isolation method, which are often used in the study of secondary school problems, are a typical complementary method, and usually some moderately difficult questions will be used.

The most important thing is to accurately understand the physical model and grasp the entire physical process. Of course, useful formulas and theorems are something that must be remembered, and this is the premise. But it's not a rote memorization, it's important to understand the physical implications.

You can try to analyze the questions when doing the exercises, and after a long time, you will find that the question types are very similar, and there are so many test points, and it is not difficult to know what it asks.

Hehe... Interest is the best teacher, first of all, you have to be interested in this new subject, followed by to be good at thinking, willing to do hands, a lot of experiments in physics can be done in life, and there is to listen well, do more exercises, summarize more, review more, I believe that you will make great progress after a period of time, in fact, there is no shortcut to learning, only diligence can learn it well, good luck!

I think that junior high school physics should be more related to reality, and I am indeed like this when I am studying, do more questions, ask questions in time, and listen carefully in class.

Hope mine can help you, thanks.

The most important thing is to accurately understand the physical model, master the whole first of all, you must be interested in this new subject, secondly, you must be good at thinking, willing to do hands-on, many experiments in physics can be done in life, and there is also to listen to lectures well, do more exercises, summarize more, review more, and finally want to say that "interest" and confidence are the best teachers to learn mathematics well. As long as you understand the importance of studying physics and chemistry, you will have infinite power and gradually become interested in physics and chemistry.

Landlord, your experience is very similar to mine, and I also felt very lost when I encountered buoyancy (of course, that was six or seven years ago), but you must know that your opportunity to really enter the discipline of physics has also come.

At that time, I took three days, and gnawed down the buoyancy part of a brand new physics workbook and many things I didn't understand before, and copied all the wrong questions, read and did it repeatedly, and then suddenly felt enlightened, and caught some physics feelings, and then I liked this course more and more, and I learned it very well, and I won a prize in the competition in high school.

The most important thing in physics is the column equations, and we must find the equality relationship, the balance of forces, the action and reaction forces, etc., and apply the specific problems to the most basic equations. The most beautiful thing in nature is symmetry, which is a classic summary of many laws of physics.

Pay attention to the premise of each formula!

Objects are in balance with each other.

Take the initiative to ask your teacher or classmates with better grades.
