How to learn physics well? How to learn physics well

Physics is very simple, mainly formulas, just listen carefully in class, and it's OK to find questions and practice a few questions if you don't know something.

If you want to learn physics well, you have to be interested and rely on yourself. However, with the new textbook and the knowledge of physics, where does the interest start? It is true that there is no interest without understanding.

In fact, when you first come into contact with physics, there is no need to go into the details of how to learn physics well, and those big truths that sound very reasonable don't actually work. The beginning of everything is difficult, and a good beginning is equal to half the success. For students who are new to physics, the question of how to learn physics well can be transformed into the question of what should be paid attention to when learning physics for the first time.

In short, there are two changes to be aware of. First, we need to change our thinking habits. Different disciplines have different characteristics and different logical systems, so when learning physics, we should change our original thinking habits, pay attention to thinking and judging according to the rules and requirements of physics, do not take it for granted, and do not follow feelings, otherwise, we will not be able to get out of the quagmire of doubt.

For example, the diameter of a piece of wire is required to be measured. The specific method is to wrap this wire tightly around a round pencil, and set the number of turns n wound on the pencil is 30 turns, measure the total "width" of the 30-turn coil 1 with a millimeter scale, and finally calculate what is the diameter d of the wire. Some students wrote this equation:

d 1 n 70 0 mm 30 2 33 mm. The teacher said that this result is wrong, and the correct result should be 2 3 mm. Some students feel that they can't figure it out, and take it for granted that the more digits after the decimal point, the better.

The results cannot be separated from the most basic experimental facts, because the tool used for the measurement is a millimeter scale, so the conclusion is only allowed to appear after the millimeter number of the millimeter number is allowed to appear. If there are two digits after the millimeter, it means that the measuring tool is accurate to the millimeter, when in fact the millimeter scale can only be accurate to the millimeter. The second is to change the learning method.

Depending on the content and objectives of learning, there will be different methods to adapt to them. Physics is a science based on observation and experiment, and it is different from the speculative knowledge that we have been exposed to before, so we should pay attention to more observations, do experiments seriously, and remember one sentence: wisdom comes in the hands.

Of course, when it comes to changing learning methods, it is inevitably a bit abstract for students who are new to physics. Everything has a process, if you want to find a good way to learn physics, you can't be in a hurry, the effective steps are: first to study and master the methods introduced by the physics teacher, and then through a period of study, summarize and explore your own effective methods.

To learn physics, we should learn physics in life, connect with life, and combine books.

The current trend towards the Physics exam is to be simpler and more fundamental. Therefore, the mastery of basic knowledge and basic skills is of the utmost importance.

These things are coming? Textbooks, of course.

The content covered in the textbook can be used as material for the exam, and it has also become a trend.

When you are in class, you must listen carefully and have a good habit of listening to lectures. Teachers are able to summarize important knowledge points, and there are also practice questions that provide timely feedback.

After class, homework must be serious and develop good homework habits. It's a check of what you've learned in class. You can tell how well you have mastered it.

After practicing, it is also necessary to have a good habit of revision. It's a further understanding of what you don't have in your grasp.

There are also some knowledge points that you need to memorize, just like 1+1=2, so don't forget to memorize some knowledge (such as concepts, definitions, formulas) because they are simple, they are the key to solving the puzzle.

As long as you can have a correct attitude, persevere, and focus on textbooks, classes, and homework, I believe that through a period of habit cultivation, your physics score will definitely improve significantly.

Carefulness is a good helper for good grades.

The best way to do this is actually your mindset and actions.

Take classes seriously, do a good job of connecting divergent thinking, and do more questions.

Learning should be arranged with a simple and feasible plan to improve the learning method. At the same time, it is also necessary to participate in school activities appropriately and develop in an all-round way. In the learning process, be sure to:

Listen more (listen to lectures), memorize more (remember important question structures, concepts, and formulas), read more (read books), do more (do homework), ask more questions (ask if you don't understand), do more hands (do experiments), review more, and summarize more. Use the method of taking class notes to focus on the lesson. Basic Essentials of Chemistry:

Proficient memory + practical operation, that is, chemistry is an experiment-based discipline, and learning should combine proficient memory with practical operation. In particular, it is easier to learn chemistry by memorizing concepts such as the periodic table, the priority of metal reactions, the conditions of chemical reactions, precipitation or gas conditions, etc. Namely:

It is necessary to memorize the position of the first 18 elements in the periodic table, the characteristics of atomic structure, and the relative atomic and molecular weights of common substances to improve the speed of problem solving. The chemical properties of chemicals should be understood and mastered, especially familiar with the writing of chemical equations and ion equations. It is necessary to have a comprehensive grasp of the use of chemical laboratory instruments, the basic operation of chemical experiments, and be able to design some typical experiments.

Physics: The key is to be able to apply and master physical ideas independently. When doing problems, you should try to draw pictures and change abstract thinking to figurative thinking.

The definition of theorems must be mastered, and several major plates must be learned: conservation of energy, law of momentum, conservation of mechanical energy, law of kinetic energy in mechanics; Lorentz force in electromagnetism, left-handed rule, right-hand rule, etc. The definition of the theorem involved must be firmly grasped.

When encountering problems, you should pay attention to the teacher's solution ideas. First of all, it is necessary to understand which of the five major blocks of physics, heat, light, electricity, and atomic physics is used to solve, and then dig out the known conditions, especially the hidden conditions. No matter how difficult the topic is, try to draw a picture, change abstract thinking to figurative thinking for state analysis and dynamic analysis, and then build a bridge between the known and unknown according to the knowledge learned, apply it independently, and cultivate a physical mind.

Through unremitting efforts, the results are improved and stabilized step by step. Do your best for the exam, be careful during the exam, and be calm when you sprint at the end. After the exam, you should summarize carefully so that you can study better in the future.

Right now: let go of the baggage, usually: study hard.

Before the exam: prepare carefully, during the exam: don't give up, after the exam:

Ordinary heart. Remember! Success always comes from unremitting efforts, and success always belongs to hard-working people.

Learn more. Practice is greater than theory.
