Why didn t I learn physics well in the 9th grade?

If you use the physics book of the people's education version, then it is time to learn mechanics, as well as optics, etc., which is a bit miscellaneous, feel a little difficult, it is normal, you don't detach physics from reality, accept physics from the perspective of life, and then ponder with your heart, do less questions but be fine, really understand the meaning of the topic, if you use the Shanghai Science and Technology Edition, it is time to learn electricity, but also to understand the basic concepts, pay attention to the understanding of the circuit, understand the circuit diagram, and then the relevant formulas to figure out the conditions for use, it will be better, I hope it will help you.

Buy more physics reference books, cover up the example problems to do, mainly the part that you don't understand, you really can't do it, just look at how the example problems are analyzed, step by step to figure it out, after you fully understand it, you can do this part of the practice questions, the questions are done more, it will be clear, the concept, the problem-solving skills are deepened in the process of solving the problem, I still advocate the sea of tactics, there is not enough practice, the physics is difficult, after doing it you have to summarize more, the learning method relies on yourself to summarize, after a long time, you like to do the problem very much, So you succeeded, I did it when I was in school, and I was the best in my grade, and the hard work paid off. Note that it is not enough to just complete the homework assigned by the teacher, and I wish you success.

It is recommended that you read the book before doing your homework every time, and if you have a notebook, you should also read it again, recall the knowledge points that the teacher talked about in class, complete the homework independently, ask if you know how to ask in time, and do a good job of preparation before class. That's how I used to learn, I always did well in physics, the key is that you have to study hard to succeed.

The homework assigned by the teacher should be done independently, and it should be no problem.

Physics should pay attention to principles, concepts and laws, no matter how they change, they cannot be separated from these.

Listen carefully in class, memorize more formulas in books, do more exercises, and use your brain more.

Learn the 9th grade physics method:

1. The basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient;

2. Do some questions independently, with quality and quantity. There should be a certain number of questions, a certain degree of difficulty, and the difficulty should be gradually superimposed;

3. Pay attention to the physical process, and be clear about the physical process, because there will inevitably be hidden dangers in solving problems if the physical process is not clear. No matter how difficult or easy the problem is, we must try to draw a picture, draw an accurate surplus diagram, and use round mountain leather gauges, triangles, protractors, etc., to show geometric relationships. Drawing can change abstract thinking into figurative thinking, and grasp the physical process more accurately;

4. Attend class, listen carefully in class, and try not to think or think as little as possible. We should learn from the teacher with an open mind, consolidate, and try to be consistent and synchronized with the teacher.

There are a lot of physics knowledge points in junior high school, and there are many extensions. Can't let up. I was good at physics in junior high school. It's always around eighty minutes. Most of them are careless points lost. My approach is also very simple. Hope it helps.

First of all, I always know the concept of the book very well and understand it well.

Second, I attach great importance to the example questions in the book and always study them. The example problems show the basic application methods and problem-solving thinking. It mainly depends on thinking and methods, if you have the conditions, you can learn with a tutorial class to expand your own learning thinking, that's how I came over, you can refer to it, and now it seems that you can also try it out for free.

Third, do the exercises. The practice of physics exercises is indispensable. But don't do all the questions, you will do a lot of useless work. The exercises in the book, the types of difficult questions, etc., are generally very standardized. From easy to difficult.

Fourth, learn to think independently. Don't ask anyone about everything. Don't always look at the answer to form a dependency. It's important to think more and have your own thinking system. It also exercises the brain.

Fifth, there will be no practice there.

Special exercises are carried out for the type of questions, knowledge points, and places that will not be conducted. Now there's a word for deliberate practice. That's what I'm talking about.

The reasons and solutions for bad physics in junior high school are introduced as follows:

There are two reasons for this:

First, if you don't have a good memory of the basic knowledge or the basic principles and laws, then these knowledge points cannot be applied to life in the learning process, or applied to solve problems. In this way, it is the most fundamental reason why you do not study well and do not do well in physics.

Second, for the study of physics is not good, many people are clever, thinking that the class listens to the class and understands the end of the matter, in fact, the class to understand is one aspect, will do the question is another aspect, then the question is to understand the knowledge and encounter the solution of practical problems, then listen to the living room teacher lecture, just can show that the teacher has explained this knowledge point, as for how to apply it or another aspect, so the physics is not good is you need to be more proficient and more to do the problem.

Solution: 1. Listen carefully and do the questions independently.

Listen carefully to the lectures and implement the three basics: the basic concepts must be clear, the basic laws must be familiar, and the basic methods must be proficient. Choose a good textbook and do some practice questions independently. There should be a certain number of questions, not too few, but more importantly, quality and a certain degree of difficulty.

Anyone who learns mathematics, physics and chemistry will not be able to learn well without going through this level. The practice of the exercises is mostly classified exercises and variant exercises. That is, the same or similar exercises are put together, and the difficulty of the exercises is progressive, increasing the difficulty little by little.

2. Learn physics to return to life.

If there is a sudden power outage at home, will you still be as scared as you were when you were a child? Eighty percent of the fuse is blown out early, go and see. In a 100-meter race, why is the timekeeper required to start the time when he sees the gun smoking, instead of hearing the gun?

You learned that the speed of light is much higher than the speed of sound, do the math, and you understand.

Why does a car have to travel some distance after braking? How to reduce the occurrence of traffic accidents when the road is slippery in rainy and snowy weather? This is related to inertia, friction.

How can you tell if a ring is pure gold? Measure mass and volume, calculate density, and compare density tables! As you learn physics, it will suddenly become clear that life is full of physics riddles waiting for you to solve.

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.

First of all, you have to be interested, junior high school mechanics is still quite simple, as long as you meditate and follow the step analysis, you can quickly solve it.
