Physics has always been a difficult subject in college entrance examination, and poor performance in physics is a common phenomenon among most senior high school students. How to improve the performance in physics? How can I learn physics well? Students with poor physics scores should take a look at it quickly!

How can senior high school physics improve grades

Memory

In the study of senior high school physics, we should memorize the basic concepts, laws and some basic conclusions, that is, the so-called most basic knowledge that we often mention. Students often ignore the memory of these basic concepts, thinking that learning physics in senior high school doesn't require rote memorization of these literal things. As a result, few students, even those in cram schools, can accurately say their physics concepts when they are asked in the general review of senior high school. I can't absolutely say how much the incomplete concept of physics in senior high school has affected your study in a certain exam or a certain stage, but I can definitely say that it has an inherent adverse effect on your understanding of physical problems and the formation of your knowledge of the whole physical system. You can't say which question in a senior high school exam will lose points because of your inaccurate concept. Therefore, learning Chinese requires memorizing famous sayings and aphorisms, learning mathematics requires memorizing basic formulas, and learning physics requires memorizing basic concepts and laws. This is the first condition and the most basic requirement for learning physics well. Without this step, the following learning is impossible.

accumulation

accumulation is the work after memorizing in the process of studying physics in senior high school. On the basis of memory, I constantly collect a lot of information about physics knowledge in senior high school from textbooks and reference materials, some of which come from a topic, some from an illustration of a topic, and some may come from a short reading material. In the process of collecting and sorting out, we should be good at analyzing and classifying different knowledge points, and find out similarities and differences in the process of sorting out, so as to facilitate memory. The process of accumulation is a process of struggle between memory and forgetting. However, it is necessary to make knowledge more comprehensive and systematic through repeated memory, and to make the relationship between formulas, theorems and laws closer, so as to achieve the purpose of accumulation. It is absolutely impossible to repeat the work like a bear breaking a stick and memorize mechanically without thinking. As a result, there will only be more memories than forgetting.

You can't just do the questions, but you should analyze more questions.

When studying physics in high school, many people like to brush the questions, but remind everyone that the number of questions done in high school is not important, and we need to analyze the questions and papers. It is not extremely difficult to make a set of physics papers, but it is not easy to really analyze the whole set of papers with your heart. Students who can really learn physics in senior high school like to analyze the papers they have done and summarize the rules of the proposer, the ideas of solving problems and the starting point. Especially in recent years, the college entrance examination questions, physics experts will study the proposers' ideas thoroughly. Tell everyone a truth: it is better to spend time and heart analyzing a topic than to brush more than a dozen topics.

Clever

On the basis of skilled physics in senior high school, it is the ability to apply knowledge. There are many solutions to the same physics problem in senior high school, and the simplest one can be selected from them. It also includes multiple problems and one solution, and a method to solve multiple similar problems. Really achieve the degree of the use of Lingqiao.

notebook/error correction book

In high school, listening is the main course, and there is also a notebook, and some things should be written down. Write down the knowledge structure, good problem-solving methods, good examples, things you don't understand, and so on. After class, you should arrange your notes, on the one hand, to "digest well", on the other hand, you should supplement your notes. Notebook is not only to remember what the teacher said in class, but also to make some reading notes. Good problems and good solutions found in your homework should also be recorded in the notebook, which is what students often call a "good problem book". Hard-earned notebooks should be numbered, studied later, and preserved for life. The physical examination center of the college entrance examination-curvilinear motion

1. Conditions for objects to make curvilinear motion

① Initial velocity and resultant force are not zero.

② they are not in a straight line.

2. Speed

① The function of external force is to change the speed (size and direction).

② the velocity direction of any point is in the tangent direction of the curve of that point.

③ The speed changes constantly during the movement, which is a variable-speed movement. If the combined force is constant, it belongs to a uniform variable-speed movement.
