Persistence is required, and only those with perseverance will succeed.
Clarify the basic concepts and familiarize yourself with where they come from and how they relate to each other.
It is necessary to do some questions independently, with quality and quantity. There should be a certain number of questions, not too many, 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.
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, you should draw as much as possible, some sketches are sufficient, and some should be precise to show the geometric relationship. Drawing can transform abstract thinking into figurative thinking and grasp physical processes more precisely.
With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.
Study materials should be well preserved, classified, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more. Marking means, for example, for practice questions, that the general questions are not marked, and the good questions, valuable questions, and error-prone questions are marked differently for future reading, and marking can save a lot of time.
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 as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.

1. Physics is a natural science, which can help solve and understand many phenomena in life. Such as the application of electricity, optics, mechanics. In daily life, we should also master the knowledge of electricity, and need to have a certain understanding of the electrical environment, circuit, power, etc., and improve our knowledge in this area by learning physics, so as to achieve safe electricity use.
2. Due to the wide range of physics, there are many occupations related to physics, and learning physics well also provides better conditions for employment.
3. Learning physics well can also cultivate one's logical thinking ability.
It will also help to understand things. In short, learning physics well can make your life better.
Physics involves all aspects of life, and it may be boring, but you can't give up.

Physics, the first role, understands the truth of things and can explain some phenomena in life. Most common things like weather changes, why do thunders occur? Why do cars have patterns on their wheels?
The second role is to use the principles of physics to make tools, the simplest such as pulleys and crowbars, until we now recruit artificial satellites, spaceships.
The third role can be the development of new materials, new technologies. From atomic energy to information networks, all modern technologies are based on physics.

The 20 th century was a century of unprecedentedly rapid development of science and technology, and human society experienced epoch-making changes one after another in scientific and technological progress. At the beginning of the century, in terms of power and information exchange, human society has entered the "era of electrification" in an all-round way. This is the result of the efforts of a group of physicists such as Ampere, Faraday, Maxwell, and inventors such as Edison in the 19th century.
Since the discovery of radioactivity at the turn of the last century, after nearly half a century of research in atomic physics and nuclear physics, physics in the 40s enabled mankind to grasp the mystery of nuclear energy and brought human society into the "atomic age". Today's application of nuclear technology is far more than providing long-term and reliable energy for society, and the role of radioactivity and nuclear magnetic resonance in medical diagnosis and improvement has been well known. This achievement is inseparable from a long list of glorious names such as Rutherford, Bohr, Einstein, Marie Curie, Heisenberg, Fermi, Hahn, etc.
In the same days, physicists invented lasers, and its theoretical basis was the stimulated emission process of light proposed by Albert Einstein in 1916. Today, laser technology has been widely used in industry, agriculture, medicine, communications, computing, military and daily life, and has become a huge industry of billions or tens of billions. "The greatest impact of science and technology on human society in the 20th century is information technology developed on the basis of modern computers.
The advent of the so-called "information age" is known as the "second industrial revolution". Indeed, computers have brought about such extensive and profound changes in human society that would have been unforeseeable 20 30 years ago. More than half a century ago, three physicists, including Bardeen, Shook and Brighton, invented the transistor, marking the birth of the information age.
From the physicist's point of view, the baby was conceived in the womb for at least 20 years. That is to say, after the establishment of quantum mechanics in the 20s, physicists developed Fermi-Dirac statistics, band theory, and since then the concepts of electrons and holes have been developed. Later, n-type and p-type semiconductors were produced by doping, which laid the foundation for the invention of transistors.
The above results are linked to a series of brilliant names of physicists—Schrödinger, Heisenberg, Dirac, Pauli, Bloch, Sommerfeld, etc. Since the advent of transistors in the late 40s, integrated circuits have been made in the 60s, and since the late 70s, they have developed into LSI and then VLSI integrated circuits, and the integration has increased at a rate of 1,000 times every 10 years.
In the eyes of some people, the contribution of physics to high technology belongs to the past, and today's development of our country: the key to high technology lies in new materials and new processes. As everyone knows, the microelectronic processing and analysis methods themselves, such as ion implantation, laser annealing, Rutherford backscattering spectroscopy, Auger electron spectroscopy, X-ray luminescence spectroscopy, secondary emission ion mass spectrometry, as well as high-resolution electron etching and synchrotron radiation lithography, are not transplanted from the laboratories of various branches of physics to industry!

<> understanding and views of physics are as follows:
1. Physics is a regular summary of people's knowledge of the transformation of matter in inanimate nature;
2. Physics can be divided into two types: movement and transformation, one is the extension of early people's sensory vision, and the other is the results of experiments obtained by modern people through the invention and creation of scientific instruments for observation and measurement;
3. Physics can be divided into two parts: micro and macroscopic, macroscopic is not to analyze the individual effect of the particle group and directly consider the overall effect, which has appeared in the earliest days, and the theory of microphysics has been gradually improved with the development of science and technology;
4. Physical ideas and methods are not only valuable to physics itself, but also have important contributions to the development of the whole natural science and even social science.
5. Physics and Metaphysics.
The relationship is based on the objective principles of non-empiricism that arise from constant reflection on metaphysics, and the theory of physics can be judged in its own scientific terms.

Physics expands the boundaries of our knowledge of nature. Physics is the basic knowledge required for modern technological advances, which will continue to drive the engines of the world economy. Physics contributes to the infrastructure of technology, providing the trained personnel needed for scientific progress and the use of inventions.
Physics is an important part of the education of chemists, engineers, computer scientists, and other physical and biomedical scientistsPhysics is a part of natural science, which is a discipline that studies matter, energy and their interactions, which not only includes the exploration of the universal and basic laws of the material world, but also has a strong role in promoting the development of other natural sciences and the social productive forces of science and technology. Physics is a basic discipline that is closely related to other natural sciences, such as astronomy, geography, biology, chemistry, etc.
We study physics not only to understand the objective world, but more importantly, to use physics knowledge to transform the world, and every major breakthrough in science and technology is inseparable from physics, serving the socialist modernization of the motherland and contributing to human civilization. At present, many middle school students are for the college entrance examination, and physics accounts for a large proportion of physics in the science and science system, but I think there are some other reasons. In fact, how many physics problems do we have in our daily lives!
In fact, life is closely related to physics all the time, such as overweight and weightlessness when taking an elevator, such as the immeasurable force of an egg hitting a stone, such as the involuntary tilting of the body when parking, etc., these are the objective existence of physical phenomena. Sometimes I see a marketing student selling sensors for middle school physics experiments, but they don't understand the experimental principle and can't show the experiment in person; Many people later realized that they always wanted to avoid the annoying physics, but they didn't expect that their future work would always be free from the influence of physics. Physics and beauty also have a subtle connection.
For example, the shape of the human body or some animals is exactly the same on one side and the other, it can be folded and overlapped, it has left and right symmetry, and it also gives people a sense of symmetry and balance. Another example is a bamboo slub or a string of beads, moving in parallel at certain intervals, the figure is completely repeated, it has translational symmetry, it gives people a coherent and smooth feeling. Over time, these symmetrical sensibilities became an aesthetic criterion, widely used in architecture, plastic arts, painting, and arts and crafts decoration.
You can see it from many famous Chinese and foreign architectural and art treasures. The architecture of the Temple of Heaven, the building of Tiananmen Square, the building of the promenade of the Summer Palace, as well as various vases, the jue of the ancients drinking and various laces, etc., are typical examples of rotational symmetry, left-right symmetry, and translational symmetry. When you are interested in physics, you will find that physics is a very good course to learn and have fun!
Learning physics well has naturally become an important mission for contemporary students.
