How to learn physics well? What is the good way to have wood

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.

Talk to me more, it should be helpful.

There are many ways to learn physics, and I personally think that it is very important to understand the concepts and formulas, not rote memorization, the concepts and formulas should correspond to the actual physical situation, you can remember some special cases, some common and commonly used physical models, etc. Generally, attention should be paid to the following three aspects: (1) Three basics.

The basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient. Regarding the basic concept, let me give you an example. For example, rate.

It has two meanings: one is to indicate the magnitude of the velocity; The second is the ratio of distance to time (as in a uniform circular motion), and velocity is the ratio of displacement to time (in a uniform linear motion). As for the basic law, for example, there are two formulas for calculating average velocity, which are often used v=s t, v=(vo+vt) 2.

The former is defined and can be applied to any situation, while the latter is derivative and is only suitable for doing uniform speed linear motion. Let's talk about the basic methods, for example, the holistic approach and the segregation method, which are often used in the study of secondary school problems, are typical complementary methods. Finally, there is one more issue, which belongs to the three basic issues.

In the process of learning physics, we summarize some concise, easy-to-remember and practical inferences or assertions, which are very useful to help solve problems and learn physics well. For example, "the tension is equal on the same rope"; "Velocity is maximum when acceleration is zero"; Wait a minute.

2) Do the questions independently. It is necessary to do some questions independently (meaning not relying on others) and with quality and quantity. There should be a certain number of questions, 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.

c) Physical processes. 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, try to draw a diagram, such as a force analysis diagram, some can draw a sketch, some to draw an accurate diagram, to use a compass, triangle, protractor, etc., to show the geometric relationship.

For example, when learning magnetic fields in the future, drawing can change abstract thinking into figurative thinking and grasp the physical process more accurately. With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.

Observe more and see if you can explain the physical phenomena you see in your daily life with what you have already learned.

Physics is almost the closest subject to our daily lives. Mathematics is the most useful, but it is abstract, and it is only with physics that many physical phenomena in life are connected to mathematics.

Physics is accompanied by mathematics, and these two courses complement each other. Without mathematics, physical calculations are problematic, and some concepts of physical mathematics are not easy to understand.

Some basic concepts of physics must be remembered and fully understood, and some basic laws must be firmly remembered and turned into your own way of thinking.

For example, buoyancy, mass, force, pressure, velocity, distance, time, energy, etc., and the relationship between these quantities, and many other things start with these.

For example, energy, whether it is electricity, dynamics, or fluid mechanics, is inseparable from energy. If you look closely for the relationships between the various physics contents, you will find that in the end, they are all related to energy, and they can all be connected by energy and can be converted into other content. It provides a wide range of association space for developing problem-solving ideas.

For example, consider voltage as height, quantity as mass, and electric field force as gravity. Isn't that very helpful in understanding the content of the electrostatic field? When you connect these things one by one, you will find that after learning mechanics, then learning the content of electrostatic fields is almost a review of mechanics.

Be good at connecting, associating, drawing inferences, summarizing the commonalities of content in different fields, and finding out the differences. It can not only open up ideas, but also help memory.

Another example: through the correlation of energy, very complex content can be simplified. A particle with an initial velocity of 0, no matter how complicated the way it slides down along the route, as long as the friction force is not considered, the speed to the lowest point is constant.

Because energy is conserved, potential energy is all turned into kinetic energy.

As long as you think about many things and associate them more, you will find that they are very simple.

You must be very familiar with the topics in your workbook and practice them several times.

Electricity: Reading, reading, reading.

Diagram reading is to learn to read circuit diagrams and learn the application of circuit diagrams.

Meter reading refers to learning to distinguish the current circuit meter, and reading the number refers to understanding the physical quantity represented by the number, understanding its physical meaning, and learning to use formulas flexibly to calculate.

Mechanics: The comprehensive method is force analysis.

The core means of force analysis are divided into two steps: 1. Isolation review 2. Comprehensive finalization.

1 Isolation review refers to the stress state of a single analyzed object.

2. The comprehensive decision refers to the determination of the overall force state after a single analysis of the force state of the object.

You have to be meticulous in doing physics in order to get a high score.

As soon as I saw this friend, I was in the same way that I had been trapped by physics for a long time, and eighty percent of them were girls.

I would like to introduce you to the learning method of Li Xiaopeng, the top student in the college entrance examination, and don't take a try.

First, the fundamental law of learning - clear thinking.

1. Simple learning - focusing on the learning of knowledge points - understanding, memorization, and practice;

2. Systematic learning - induction and summary - skeleton, sorting and enrichment;

Complete learning is a combination of 1 and 2.

2. How to use the fundamental laws to learn:

1. Problems: many knowledge points and a wide range of knowledge;

2. Problem solving process: the process of establishing the connection between various knowledge points;

3. Unable to solve the problem: breakpoint;

4. To learn systematically: there is an overall game of chess in mind;

3. How to Conduct Systematic Learning:

1. Establish a knowledge framework;

2. Fill the skeleton with flesh and blood;

3. Find out the connection between the vertical and horizontal directions of each part.

Fourth, the complete process of systematic learning:

1. Draw a complete knowledge structure diagram;

2. Connect the knowledge points in this diagram with the specific learning content (fill in the flesh);

Transpose this interconnected knowledge system into the brain as a whole.

The concept should be deeply understood, and the concept should be able to be accurately expressed in their own language, and the understanding does not necessarily come from the sea of questions.

The key to physics is still an understanding subject, so I don't think it's important to do too many questions, the important thing is the understanding of concepts and theorems.

Sort through all the concepts and replace them with micro-comprehension, and don't memorize them, and everything should be taken for granted, not memorized.
