Can I really learn physics well?

Physics is everywhere, and I believe that with unremitting efforts, you can learn this subject well.

Judging from your phenomenon, it should be caused by a poor understanding of the basics. Can you describe the concepts you've learned in your own words? If you can, it means that you really understand, and it is not difficult to remember.

In terms of analyzing friction, many students have questions like you, and they feel that it is difficult to analyze correctly, and the reason is that they have not learned the force analysis well. When analyzing whether there is friction, you can use the hypothetical method: that is, assuming that friction does not exist, to see whether the motion state of the object is consistent with the conditions given in the title, if it is consistent, there is no friction between the objects, if it is inconsistent, it means that there is friction between the objects;

Momentum, just remember that momentum is the mass of the object multiplied by the mass, there are beginnings and ends, impulse refers to the cumulative effect of force on the object, equal to the force multiplied by the action time, they are linked by the momentum theorem. In addition, it is important to remember the conditions under which the law of conservation of momentum applies and the types of problems to be solved. Characteristics and solutions of collision problems, etc. You have to take a good look at the concepts and laws of this place, and if you really understand it, you will be able to do it.

Electricity includes a lot of parts, including electrostatics and constant current, but I feel that you should have a problem with the electrostatic part, and you can learn it as mechanics here; In addition, grasp the basic concepts and basic laws.

The above is a little bit of advice I have given you, I hope it can be useful.

1.Physics learning is all about comprehension. Don't memorize concepts, ask a few more whys, and dig up things from each word.

2.For calculation questions, write out what you know first, think more when you write, and know what this problem can solve? When doing questions, start with the requirements.

I want to ask him what formula he should use, after writing the formula, look at the corresponding quantity to know what, I don't know if I can find it? If you can't find it, it's mostly because this method can't work. If there is any other formula for the quantity you are looking for, if so, you can think about it in the same way.

If it doesn't work, just think about what the required quantity is equal to, and find that equal amount in your thoughts.

3.It is very important to review the questions in the process of doing physics questions, and you can circle the keywords.

When solving problems, you should be good at pondering, summarizing experience and problem solving methods, you can ask teachers or classmates more first, compare the correct solution with your own thinking, find out the shortcomings or thinking mistakes, summarize more lessons and lessons, and also refer to the detailed information of the test questions to learn problem-solving skills. I'm trying to do more questions, and I'll get it straightened out slowly.

Read the questions carefully and be careful. You should concentrate your energy and not use it for two things.

In fact, it's just doing the topic, and you do too little on the topic.

Persistence is required.

Clarify the basic concepts and familiarize yourself with where they come from and how they relate to each other.

It is necessary to do some questions independently, with quality and quantity. There should be a certain number of questions, not too many, not too few, but also a certain quality, that is, a certain degree of difficulty. Anyone who learns mathematics, physics and chemistry will not be able to learn well without going through this level.

Solving problems independently, sometimes slowly, sometimes detours, sometimes even unable to solve them, but these are normal and the only way for any beginner to succeed.

It is necessary to be clear about the physical process, and there is inevitably a hidden danger of solving the problem if the physical process is not clear. Regardless of the difficulty of the topic, you should draw as much as possible, some sketches are sufficient, and some should be precise to show the geometric relationship. Drawing can transform abstract thinking into figurative thinking and grasp physical processes more precisely.

With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.

Study materials should be well preserved, classified, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more. Marking means, for example, for practice questions, that the general questions are not marked, and the good questions, valuable questions, and error-prone questions are marked differently for future reading, and marking can save a lot of time.

It is necessary to attach importance to the knowledge structure and systematically grasp the knowledge structure, so that the scattered knowledge can be systematized. It is as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.

I don't know what grade of physics you are, but I personally think that physics is very close to our lives, and we can understand a lot of things that we don't usually understand. So I am personally interested in physics.

To learn this thing is to be interested. So you can nurture your interest in physics. From the bits and pieces of life, it turns out that physics is very useful.
