How can you have a physical way of thinking?

The decomposition of forces, sin, cos must be skillfully used, and force analysis must be passed - you can improve by doing problems. (Personal suggestion, if you really want to do it well, just do the questions yourself and change the questions yourself, don't be ashamed to ask the teacher or anything, learning is your own business.) Do more problems related to force analysis, such as adding a block of wood to a long block, moving together or giving a force in an instant, etc., for you to find the result.

It's painful and hard to figure out at first, but when you can't think of it or make an answer that you think is absolutely wrong, then read the analysis and analyze it step by step. In this way, you will soon be able to grasp the basic question types and thinking directions. All that's left is practice, improvement.

That's basically all there is to mechanics, and then there's Newton's laws, which can be solved with a little look.

By the way, I'm a sophomore in high school, and my grades are average, but I'm definitely super interested in physics and my grades are much better than normal subject grades The above is just my learning method (physics and math class, I'm basically doing my own thing. Also, your question, is it junior high school or high school physics? When I was in junior high school, I didn't think I needed to buy extracurricular books.

In junior high school physics, only formulas are used, and there is no need for particularly deep thinking. Just make more papers and listen to the teacher. If you want to have a book similar to the lecture in high school, "Wang Houxiong" is very good.

I think it's good to want to do more novel questions and "test points". Then it's a five-year college entrance examination and a three-year simulation (this, it's better to buy it after the third year of high school.) ）

Physics is about analysis and imagination, and if you only care about mathematics, you can only become a mathematician. In fact, as long as you ask more why, why is this so, why can't it not be like this, what would happen if it wasn't like this, think about it more, and slowly feel it.

It means that the thinking methods commonly used in learning physics, thinking about the results of their activities, belong to cognition.

1. Reverse thinking.

Reverse thinking is a scientific thinking method to solve physical problems, for some problems, the use of conventional thinking methods will be very cumbersome or even impossible to solve, and the use of reverse thinking, that is, the "end state" of the motion process as the "initial state", reverse study of the problem, can make the physical situation simpler, the physical formula can also be simplified, so that the problem is easy to solve, can receive twice the result with half the effort

2. Symmetry method.

Symmetry is a certain invariance that exists when things change In nature and natural science, there is a beautiful and harmonious symmetry phenomenon When using symmetry to solve problems, it is sometimes possible to see the answer at a glance, greatly simplifying the steps of solving problems.

From the perspective of scientific thinking methods, the most prominent function of symmetry is to enlighten and cultivate students' intuitive thinking ability The key to solving problems with symmetry is to keenly see and grasp the symmetry of things in a certain aspect, and these symmetries are often the shortcut to the answer.

The cause of the movement of consciousness is to think, and thinking is the forward movement of consciousness.

In the life activities of the living body, under the action of the form of consciousness, when there is a difference between the form of things in the original consciousness and the form of the new thing, the consciousness of the living body achieves the cause of the form of consciousness movement in the difference, and the movement of consciousness caused by this is the thinking itself, the content of the movement of consciousness is the essence of the problem, and the problem of essence is the subject of the problem.

The direction of consciousness is explained by the consciousness of the subject of consciousness, and the reference of consciousness is the reference to the inertia of things, that is, the formal expression of the expression of habitual behavior in consciousness. When the development and change of things have gone beyond the impression of consciousness, the attachment of consciousness in the impression is the inertia of consciousness, and in terms of consciousness, it is the forward direction of consciousness, and in the forward movement behavior of consciousness inertia, thinking is considering the change.

Physical thinking, that is, scientific thinking in physics, is an indirect, generalized and active reflection of the intrinsic attributes, internal regularities and connections and interrelationships between objective physical things (including physical objects, physical processes, physical phenomena, physical facts, etc.) by the conscious human brain. The subject of physical thinking is a person with special physiological and psychological mechanisms, and the object of physical thinking is an objective physical thing.

Physics is a discipline that studies the most general laws of the motion of matter, the basic structure of matter and the interaction between substances. In order to understand the essential laws and characteristics of the movement and interaction of substances in nature, we must form a complete and profound reflection of the essence of the entire physical world in our minds, and we must form a clear physical picture of the observed physical phenomena, physical facts, and physical processes in our brains, and repeatedly process them, rationally transform them, and extract them from the rough and refined, so as to elevate perceptual understanding to rational understanding, which is physical thinking.

Physical thinkingThe so-called physical thinking is the scientific thinking in physics, which is the indirect, generalized and active reflection of the essential attributes, internal regularities and connections and interrelationships between physical things (including physical objects, physical processes, physical phenomena, physical facts, etc.) of objective physical things (including physical objects, physical processes, physical phenomena, physical facts, etc.).

What is Thinking? Each person's thinking height is different, which leads to a different psychological structure. The structure is roughly divided into five layers: self-thinking, empathy thinking, social thinking, spatio-temporal thinking, and philosophical thinking.

Physical thinking means that how to generalize is more abstract, there is that kind of space, there is that kind of plane, you need to think about it, to consider.

5. Equivalence Thinking and Connection Thinking Equivalence thinking is a way to put forward some plans and ideas for the object of study based on the same effect. This method has the effect of enlightening thinking, expanding horizons, and touching on the bypass.

For example, in mechanics, the resultant force is the equivalent substitution of the component force, the particle is the equivalent substitution of the object, and the resultant motion is the equivalent substitution of the partial motion; For the convenience of research, the variable speed motion is equivalent to the uniform motion of the variable speed motion, the impulse of the variable force is equivalent to the impulse of the constant force, and the work of the variable force is equivalent to the equivalent thinking method. 6. Image Thinking Image thinking is a way of thinking that uses the physical meaning of physical images and combines mathematical knowledge to analyze and solve physical problems. The use of physical images to solve physical problems is intuitive, visual, and convenient.

7. Critical Thinking and Limit Thinking Critical thinking is a way of thinking that uses the condition that an object is in a critical state to solve physical problems, and when dealing with complex problems, it can appropriately lead physical changes to the limit, and then analyze its limit state, or substitute characteristic data for discussion, so as to prompt the essence of the problem and simplify the process. Limit thinking is based on known empirical facts, starting from the principle of frontierality, extrapolating the studied phenomena and processes to the ideal extreme value for consideration, so that the main factors or the essence of the problem can be quickly exposed, so as to make correct judgments. Critical thinking and limit thinking can often simplify the complex into the difficult to solve physical problems.

Enhance the understanding of thinking skills.

The so-called thinking ability is the ability of people to use the basic methods of thinking, such as comparison, identification, generalization, analysis, synthesis, induction, deduction, hypothesis and imagination, to form concepts, and to gain an understanding of the nature and regularity of things through judgment and reasoning. In order to improve the ability to think in physics, it is necessary to make great efforts to understand the concepts of physics. In the process of studying physics, it is necessary to constantly summarize and study how to understand concepts, and constantly improve the ability to correctly understand and master physical concepts and laws.

All of students' learning activities are inseparable from thinking, and thinking ability is the core of learning ability.

Thinking ability includes comprehension, analysis, synthesis, comparison, generalization, abstraction, reasoning, argumentation, judgment and other abilities. It is the core of the whole wisdom and participates in and governs all intellectual activity. Whether a person is smart or not, whether he is wise or not, mainly depends on whether his thinking ability is strong or not.

The most fundamental way to make oneself smart and wise is to cultivate thinking ability.

Cultivate students' research thinking skills through demonstration experiments.

Educational psychologists generally believe that physical demonstration experiments can provide students with perceptual cognitive materials, and on this basis, guide students to explore new knowledge and skills, and students will consciously accompany the teacher's demonstration and actively think while observing, which is an important opportunity for cultivating students' research thinking.

To improve the ability to think in physics, we can only follow this way of analysis on a regular basis.

As well as the direction of theoretical research to slowly exercise.

Learn more, observe more, think more.

It's just that you only think about the physical properties of the object, such as its mass, its velocity, and nothing else.
