Physics is a natural science course that is difficult to learn. You can't learn by rote. You can recite it word for word, but you still can't do the problem. Let's talk about physics in junior high school, senior high school and university. There are many qualitative things in junior high school, quantitative things in senior high school and quantitative things in universities, which have to be calculated by advanced mathematics. So, how to learn physics well?

If you want to learn physics well, you should not only learn physics well, but also learn mathematics, chemistry, Chinese, history and other courses well. In other words, you can learn what you have learned. In fact, in school, the students we meet who learn well do well in all subjects, and the students who learn poorly do poorly in all subjects. This is basically a question of learning methods, except for the innate factors of small probability.

Who doesn't want to be a good student, but to be a really good student, the first thing is to study hard, that is, to dare to endure hardships, cherish time and study tirelessly. Establish confidence, firmly believe that you can learn any course well, firmly believe in the "law of conservation of energy transformation", and firmly believe that if you make a contribution, you should gain something.

Please read the following three quotations about this article:

I never believe in any innate or acquired talent, and I can succeed without firm and long-term efforts.

-Dickens (English writer)

The main reason why some people can go far beyond others is not so much genius as his indomitable spirit of concentrating on his studies and not giving up until he reaches his goal.

-Dalton (British chemist)

The fastest and slowest, longest and shortest, most common and most precious, most easily overlooked and most regrettable thing in the world is time.

-Gorky (Soviet writer)

The first item mentioned above should be said to be the problem of learning attitude and thinking method.

The second is to understand that there are eight links in learning as a student: making a plan → previewing before class → concentrating in class → reviewing in time → independent homework → solving problems → systematic summary → extracurricular learning. The most important thing here is: concentrate in class → review in time → independent homework → problem solving → systematic summary, these five links. There are many learning methods in the above eight links, and the following is for physics.

(1) Sanji. Basic concepts should be clear, basic laws should be familiar, and basic methods should be mastered. About basic concepts, such as speed, it has two meanings: one is to express the size of speed; The second is the ratio of distance to time (for example, in uniform circular motion), while speed is the ratio of displacement to time (for example, in uniform linear motion). Taking the basic law as an example, there are two formulas for calculating the average speed, V = S/T and V = (VO+VT)/2. The former is a definition, which is applicable to any situation, while the latter is a deduction, which is only applicable to the situation of doing uniform linear motion. For example, holism and isolationism, which are often used in studying middle school problems, are typical complementary methods. Finally, a question belongs to three basic problems. That is, in the process of learning physics, we sum up some concise and practical inferences or conclusions, which are very useful for solving problems and learning physics well. For example, "the potential decreases along the electric field line"; "The tension on the same rope is equal"; "Maximum speed when acceleration is zero"; "Lorentz force does not do work" and so on.

(2) Do the problem independently. Do some problems independently with good quality and quantity (meaning not relying on others). There should be a certain number of questions, not too few, but also a certain quality, that is to say, it is difficult. Anyone who studies math and physics can't learn it well. Solving problems independently may sometimes be slower, sometimes detours, and sometimes even impossible, but these are normal and none of them.

Physical process. To clarify the physical process, there must be hidden dangers in solving problems. No matter how difficult the topic is, try to draw as much as possible. Some can draw sketches, others can draw accurate maps, and they can use compasses, triangles, protractors and so on. To represent geometric relationships. Drawing can turn abstract thinking into image thinking and grasp the physical process more accurately. With drawings, we can carry out state analysis and dynamic analysis, as well as state.

Class. Listen carefully in class and don't think or think as little as possible. Don't be self-righteous, learn from the teacher modestly. Don't give up listening just because the teacher speaks simply. If this happens, it can be regarded as review and consolidation. Try to be consistent and synchronized with the teacher, you can't do it yourself. Otherwise, it is tantamount to self-study. After getting started, you are allowed to have certain activities.

(5) notebook. Class is mainly about listening to lectures, and you should have a notebook. Some things should be written down. Knowledge structure, good problem-solving methods, good examples, places that I don't understand well, and so on. After class, you should also sort out your notes, on the one hand, for "digestion", on the other hand, you should also supplement your notes. Notebooks should not only record what the teacher said in class, but also make some reading notes you found in your homework. It is what students often call a "good textbook". Hard-made notebooks should be numbered, studied in the future and preserved for life.

(6) learning materials. Learning materials should be well preserved, classified and marked. The classification of learning materials includes exercises, test papers and experimental reports. Correcting means, for example, exercises, good questions, valuable questions and error-prone questions are not corrected, but corrected separately for future reading, which can save a lot of time.

(7) time. Time is precious. Without time, it is too late to do anything, so we should pay attention to making full use of time, which is a very superb art. For example, we can save time by using the learning method of "recalling". Before going to bed, waiting for the bus and walking on the road, you can recall the lessons of the day one by one, so that you can learn them again and again to achieve the purpose of strengthening. You may think of some problems when you walk. People who study physics often have several problems in their minds that they can't do and won't forget. I don't know when they will make a breakthrough and find the answer to the question.

(8) learn from others. Learn from others with an open mind, from classmates, from people around you, and see how others learn. I often have "academic" exchanges with them, teach and learn from each other, and never be self-righteous. Don't be conservative. Tell others when you have a good method, so that others will tell you when you have a good method. I have several good friends in my studies.

(9) Knowledge structure. We should pay attention to the knowledge structure and master it systematically, so that scattered knowledge can be systematized, from the whole physical knowledge structure to the mechanical knowledge structure, and even to chapters, such as the knowledge structure of statics.

mathmatics The calculation of physics depends on mathematics, which is too important for learning physics. Physics is difficult to do without mathematics as a calculation tool. In the physics department of a university, mathematics and physics are equally important. We should learn math well and make good use of this powerful tool.

(1 1) Sports activities. Healthy body is the guarantee of good study, and vigorous energy is the guarantee of high efficiency in study. You should always take part in sports activities, know one or two sports methods, and take part in sports activities all your life, without stopping. Just out of interest, fishing for three days and drying the net for two days will not do much good to your health. You should exercise consciously. You should ensure enough sleep. You can't increase your study time by reducing your sleep time, which is not desirable. You can't get a little good grades at the expense of overdraft health. You can't talk about the so-called "sprint" and "struggle" easily, and you should also pay attention to regularity in your study, that is to say, you should always work hard and have no accidents.

The above simply said some learning methods, more specifically, more effective learning methods need to be explored and summarized by yourself in the learning process, and other people's methods must be tested by yourself to become your own things. I hope you can achieve good results!
