Topics in physics are all school curriculum. Simple and clear teaching of physics. School physics topics

Physics comes to us in the 7th grade of a comprehensive school, although in fact we are familiar with it almost from the cradle, because it is everything that surrounds us. This subject seems very difficult to study, but it needs to be learned.

This article is intended for persons over 18 years of age

Have you already turned 18?

You can learn physics in different ways - all methods are good in their own way (but they are not the same for everyone). The school curriculum does not provide a complete understanding (and acceptance) of all phenomena and processes. The culprit is a lack of practical knowledge, because the learned theory essentially gives nothing (especially for people with little spatial imagination).

So, before you start studying this interesting subject, you need to immediately find out two things - why you are studying physics and what results you expect.

Do you want to pass the Unified State Exam and enter a technical university? Great - you can start distance learning on the Internet. Now many universities or simply professors conduct their online courses, where they present the entire school physics course in a fairly accessible form. But there are also small disadvantages: first, get ready for the fact that it will not be free (and the higher the scientific title of your virtual teacher, the more expensive), second, you will only teach theory. You will have to use any technology at home and independently.

If you simply have problematic learning - a discrepancy in views with the teacher, missed lessons, laziness, or the language of presentation is simply incomprehensible, then the situation is much simpler. You just need to pull yourself together, and pick up the books and teach, teach, teach. This is the only way to get clear subject-specific results (in all subjects at once) and significantly increase the level of your knowledge. Remember - it is unrealistic to learn physics in a dream (even though you really want to). And very effective heuristic training will not bear fruit without a good knowledge of the basics of the theory. That is, positive planned results are possible only if:

qualitative study of theory;
developmental education in the relationship between physics and other sciences;
performing exercises in practice;
classes with like-minded people (if you really feel like doing heuristics).

Starting to learn physics from scratch is the most difficult, but at the same time the simplest stage. The only difficulty is that you will have to remember a lot of rather contradictory and complex information in a hitherto unfamiliar language - you will need to work hard on the terms. But in principle, this is all possible and you don’t need anything supernatural for this.

How to learn physics from scratch?

Don't expect that the beginning of learning will be very difficult - it is a fairly simple science, provided you understand its essence. Don’t rush to learn a lot of different terms - first understand each phenomenon and “try” it on in your everyday life. This is the only way physics can come to life for you and become as understandable as possible—you simply won’t achieve this by cramming. Therefore, the first rule is to learn physics in a measured manner, without sudden jerks, without going to extremes.

Where to begin? Start with textbooks, unfortunately, they are important and necessary. It is there that you will find the necessary formulas and terms that you cannot do without in the learning process. You won’t be able to learn them quickly; there is a reason to write them down on pieces of paper and hang them in prominent places (no one has yet canceled visual memory). And then in literally 5 minutes you will refresh your memory every day until you finally remember them.

You can achieve the highest quality results in about a year - this is a complete and understandable physics course. Of course, it will be possible to see the first changes in a month - this time will be quite enough to master the basic concepts (but not deep knowledge - please do not be confused).

But despite the ease of the subject, don’t expect that you will be able to learn everything in 1 day or in a week - it’s impossible. Therefore, there is a reason to sit down with textbooks long before the start of the Unified State Exam. And it’s not worth getting hung up on the question of how long it will take to memorize physics - it’s very unpredictable. This is because different sections of this subject are taught in completely different ways, and no one knows how kinematics or optics will “suit” you. Therefore, study sequentially: paragraph by paragraph, formula by formula. It is better to write down definitions several times and refresh your memory from time to time. This is the basis that you must remember; it is important to learn how to operate with definitions (use them). To do this, try to apply physics to life - use everyday terms.

But most importantly, the basis of each method and method of training is daily and hard work, without which you will not get results. And this is the second rule of easy learning of a subject - the more you learn new things, the easier it will be for you. Forget recommendations like science in your sleep, even if it works, it certainly doesn’t work with physics. Instead, get busy with problems - not only is it a way to understand the next law, but it's also a great workout for the mind.

Why do you need to study physics? Probably 90% of schoolchildren will answer that it is for the Unified State Exam, but this is not at all true. In life, it will come in handy much more often than geography - the likelihood of getting lost in the forest is somewhat lower than changing a light bulb yourself. Therefore, the question of why physics is needed can be answered unequivocally - for yourself. Of course, not everyone will need it in full, but basic knowledge is simply necessary. Therefore, take a closer look at the basics - this is a way to easily and simply understand (not learn) the basic laws.

c"> Is it possible to learn physics on your own?

Of course you can - learn definitions, terms, laws, formulas, try to apply the acquired knowledge in practice. It will also be important to clarify the question - how to teach? Set aside at least an hour a day for physics. Leave half of this time to get new material - read the textbook. Leave a quarter of an hour for cramming or repetition of new concepts. The remaining 15 minutes is practice time. That is, observe a physical phenomenon, do an experiment, or simply solve an interesting problem.

Is it really possible to quickly learn physics at this rate? Most likely not - your knowledge will be quite deep, but not extensive. But this is the only way to learn physics correctly.

The easiest way to do this is if you have lost knowledge only for the 7th grade (although in the 9th grade this is already a problem). You simply restore small gaps in knowledge and that’s it. But if 10th grade is just around the corner, and your knowledge of physics is zero, this is of course a difficult situation, but fixable. It is enough to take all the textbooks for grades 7, 8, 9 and properly, gradually study each section. There is an easier way - take the publication for applicants. There, the entire school physics course is collected in one book, but do not expect detailed and consistent explanations - the supporting materials assume an elementary level of knowledge.

Learning physics is a very long journey that can only be completed with honor through daily hard work.

The book by the famous US physicist J. Orear is one of the most successful introductory courses in physics in world literature, covering the range from physics as a school subject to an accessible description of its latest achievements. This book has taken pride of place on the bookshelf of several generations of Russian physicists, and for this edition the book has been significantly expanded and modernized. The author of the book, a student of the outstanding physicist of the 20th century, Nobel laureate E. Fermi, taught his course to students at Cornell University for many years. This course can serve as a useful practical introduction to the widely known Feynman Lectures on Physics and the Berkeley Course in Physics in Russia. In terms of its level and content, Orir’s book is already accessible to high school students, but may also be of interest to undergraduates, graduate students, teachers, as well as all those who want not only to systematize and expand their knowledge in the field of physics, but also to learn how to successfully solve a wide range of problems physical tasks.

At present, there is practically no area of natural science or technical knowledge where the achievements of physics are not used to one degree or another. Moreover, these achievements are increasingly penetrating the traditional humanities, which is reflected in the inclusion of the discipline “Concepts of modern natural science” in the curricula of all humanities specialties at Russian universities.
The book brought to the attention of the Russian reader by J. Orear was first published in Russia (more precisely, in the USSR) more than a quarter of a century ago, but, as happens with really good books, it has not yet lost interest and relevance. The secret of the vitality of Orir's book is that it successfully fills a niche that is invariably in demand by new generations of readers, mainly young ones.
Without being a textbook in the usual sense of the word - and without claims to replace it - Orir's book offers a fairly complete and consistent presentation of the entire course of physics at a very elementary level. This level is not burdened with complex mathematics and, in principle, is accessible to every inquisitive and hardworking schoolchild, and especially to students.
An easy and free style of presentation that does not sacrifice logic and does not avoid difficult questions, a thoughtful selection of illustrations, diagrams and graphs, the use of a large number of examples and tasks that, as a rule, have practical significance and correspond to the life experience of students - all this makes Orir’s book an indispensable guide for self-education or additional reading.
Of course, it can be successfully used as a useful addition to ordinary textbooks and manuals on physics, primarily in physics and mathematics classes, lyceums and colleges. Orir's book can also be recommended to junior students of higher educational institutions where physics is not a major discipline.

Physics is one of the basic sciences of natural science. The study of physics at school begins in the 7th grade and continues until the end of school. By this time, schoolchildren should already have developed the proper mathematical apparatus necessary for studying a physics course.

The school curriculum in physics consists of several large sections: mechanics, electrodynamics, vibrations and waves, optics, quantum physics, molecular physics and thermal phenomena.

School physics topics

In the 7th grade There is a superficial familiarization and introduction to the physics course. Basic physical concepts are examined, the structure of substances is studied, as well as the pressure force with which various substances act on others. In addition, the laws of Pascal and Archimedes are studied.

In 8th grade various physical phenomena are studied. Initial information is given about the magnetic field and the phenomena in which it occurs. Direct electric current and the basic laws of optics are studied. The various aggregate states of matter and the processes that occur during the transition of a substance from one state to another are analyzed separately.

9th grade is devoted to the basic laws of motion of bodies and their interaction with each other. The basic concepts of mechanical vibrations and waves are considered. The topic of sound and sound waves is discussed separately. The basics of the theory of the electromagnetic field and electromagnetic waves are studied. In addition, one gets acquainted with the elements of nuclear physics and studies the structure of the atom and the atomic nucleus.

In 10th grade An in-depth study of mechanics (kinematics and dynamics) and conservation laws begins. The main types of mechanical forces are considered. There is an in-depth study of thermal phenomena, molecular kinetic theory and the basic laws of thermodynamics are studied. The basics of electrodynamics are repeated and systematized: electrostatics, the laws of constant electric current and electric current in various media.

Grade 11 devoted to the study of the magnetic field and the phenomenon of electromagnetic induction. Various types of oscillations and waves are studied in detail: mechanical and electromagnetic. There is a deepening of knowledge from the optics section. Elements of the theory of relativity and quantum physics are considered.

Below is a list of classes from 7 to 11. Each class contains physics topics that are written by our tutors. These materials can be used by students and their parents, as well as school teachers and tutors.
