Find the knowledge structure of high school physics, and sort out and summarize the knowledge points

Sorting out knowledge in an orderly manner is a very important task in a round of review, so how to sort out physics knowledge points? The following teachers of Chengdu Meibo will introduce you from four parts: basic knowledge, wrong question book, comprehensive test questions, and experimental questions.

1. Focus on basic knowledge.

In the review stage, the most difficult thing is to consolidate the basic knowledge, and clarify the knowledge context through the table of contents method and outline method, which is conducive to further learning; The basic concepts, basic operations, formulas and theorems should be thoroughly understood and flexibly used.

2. Focus on the wrong question book.

Error books are one of the important tools for physics learning, and learning physics knowledge is the process of making mistakes from less to more and then to less. Sorting out the wrong questions is a process of accumulation from less to more, and then gradually reducing the number of mistakes is the process of digesting and absorbing physics knowledge. Only by continuously improving the ability to check and fill in the gaps can we continuously improve the ideas and strategies for solving problems in physics.

3. Take the comprehensive test question as the center.

Comprehensive test questions are commonly referred to as "big questions", which usually test multiple knowledge points and require students to have strong comprehensive analysis skills. Comprehensive test questions are "frequent visitors" in the college entrance examination in recent years, so students should pay attention to them. Of course, the comprehensive test questions seem difficult, in fact, if we learn to "peel back the cocoon" and divide the big requirements into small knowledge points, we can quickly sort out the clues and complete the answers.

4. Centered on experimental topics.

If you can sort out the knowledge of experimental principles, experimental procedures, experimental phenomena, experimental results, etc., then you can basically get a high score for experimental questions. In physics, whether it is mechanics, electromagnetism, or optics, we all explain relevant theories through various experiments, and if we can master the experimental problems, we will also be able to understand the corresponding physics knowledge.

Therefore, in a round of review, sorting out physics knowledge from the above four aspects can clarify the context and form a knowledge system faster.

8. Molecular kinetic theory, heat and work, gases.

1.Molecular kinetic theory.

1) Matter is composed of a large number of molecules, and the order of magnitude of molecular diameter is generally 10 -10 m

2) The molecules never stop doing random thermal motion.

Diffusion: When different substances come into contact with each other, they can enter each other. The higher the temperature, the faster the diffusion.

Brownian motion: The irregular motion of tiny particles suspended in a liquid (or gas) seen under the microscope is caused by the imbalance of the impact of liquid molecules on tiny particles, and is a macroscopic reflection of the never-ending irregular motion of liquid molecules. The smaller the particles, the more pronounced the Brownian motion is; The higher the temperature, the more pronounced Brownian motion is.
