First of all, we must know some basic definitions, such as mass, weight, buoyancy, conservation of energy, etc., and then we must memorize some basic formulas and conversion formulas, and then establish physical models from the perspective of life, so that the combination of the three can overcome the difficulties of physical learning.

1. Comprehensive review.
It should be understood that knowledge and ability are inseparable, and generally speaking, the examination of knowledge and ability in the high school examination questions is combined. A question tests both knowledge and ability, and often several abilities. We should not simply associate certain knowledge with certain abilities.
Obviously, a person with poor knowledge cannot have strong abilities, therefore, candidates should review the knowledge comprehensively and not leave it out.
A comprehensive review is not a mechanical, simple review of the entire knowledge. A physical theory composed of physical phenomena, physical concepts, laws, etc., is like a big tree, and each part of the content is closely related to form an organic whole, with a backbone, branches, leaves, etc. When reviewing all the knowledge chapter by chapter and section by section, it is necessary to pay attention to deeply understanding and experiencing the internal relationship between various knowledge points, establish a knowledge structure, so that you can have rich and systematic physical knowledge, gradually understand the status and role of each knowledge point, distinguish the main and secondary, and understand the essence of the theory, which is the basis for improving your ability.
-
Listening carefully in class is enough.
-
Memorize what should be memorized and practice more questions.
-
You have to think more, think about the physical process in your mind first, and draw pictures diligently, because you can't do physics problems without drawing. Diagrams are the most important tool to help you think.
As for formulas, it's good to memorize, and if you do more questions, you will naturally become familiar with them.
-
It is a good idea to make a diagram of the knowledge structure and imagine what the diagram looks like when you do the problem.
If you give a condition on the question, you can get the corresponding condition, that is, you can see a physical quantity and find a formula that contains this physical quantity. (Calculation Questions).
When doing the experimental questions, you should be very proficient in the experiments in the textbook, so that there will be no major problems.
For fill-in-the-blank selection and circuit analysis, it's up to you to do more questions, and it's up to you to find your own way!

Listen and watch more Take notes Memorizing notes Listen carefully in class and remember what the teacher says about the key points to remember each concept you learn is to remember the following points:
1.Symbol. 2.Formula.
3.Unit. 4.Conception.
5.Learn to make comparative judgments (e.g. velocity, specific heat capacity).
6.How to do the question How to do the question.
The last one is: listen to what the teacher says, and you must listen to the main point that the teacher says.

Easy to learn the way to physics:
First, three basics. The basic concept of Pai Lao should be clear, the basic laws should be familiar, and the basic methods should be proficient.
2. Do the questions independently. It is necessary to do some questions independently, with quality and quantity. There should be a certain number of questions, not too few, but also a certain quality.
Third, it is necessary to be clear about the physical process, and there will inevitably be hidden dangers in solving the problem if the physical process is not clear. Regardless of the difficulty of the problem, you should try to draw a picture, some can draw a sketch, some need to draw an accurate map, and use a compass, triangle, protractor, etc., to show the geometric relationship.
Fourth, it is necessary to attach importance to the knowledge structure and systematically grasp the knowledge structure, so that the scattered knowledge can be systematized. It is large to the knowledge structure of the whole physics, to the knowledge structure of mechanics, and even to the specific chapters, such as the knowledge structure of statics.

Read books, read literature, and do experiments.

The main thing is to figure out the theorems and principles and formulas in the textbook. To understand the reason, you can also buy a set of simple questions, and if you can't do it, you can flip through the book or ask the teacher to figure it out.
First of all, listen well in class, don't get distracted, and remember the knowledge that the teacher says, especially those formulas. >>>More
Physics is a science based on observation and experimentation. You should think more, learn more, and do more. According to the requirements of the course standard, the difficulty ratio of the test questions is 7:2:1 >>>More
In high school, chemistry, you have to memorize the laws of each chapter of knowledge, sometimes, the law is an important guarantee to draw inferences, small knowledge points or rote memorization, if you remember the physical properties between chemical formulas, chemical properties and other single knowledge, drawing ** memory is a good method, if it is a chemical reaction in the organic, it is represented by drawing and arrows. There are many hints in the inference questions that are special, so these special positions, you have to memorize them, you think you can't remember, write them in a book alone, when you have nothing to do, take it out and take a look, read more, you will remember almost, special chemical equations such as fe and hno3 different reaction equations, special color reactions, special colors of substances, are the focus. Strong reasoning and guessing skills are required. >>>More
Hehe, what do you have to do after the exam.
Physics is a very logical subject, and learning physics well is not only based on certain mathematical knowledge, but also has strong logical thinking ability. >>>More
