How to do good in high school physics, how to do well in high school physics?

The most basic thing is to prepare for the lesson, only by preparing the lesson can we better guide the students, and secondly, we should use more profound and influential teaching tools to guide the students. Stimulate students' interest in learning

High School Physics is a book published by the People's Education Publishing House, and the authors are the People's Education Publishing House, the Institute of Curriculum and Textbooks, and the Research and Development Center of Physics Curriculum and Textbooks.

High school physics is one of the basic subjects of science (natural science) in high school. This book is a standard experimental textbook for the general high school curriculum.

How to learn the knowledge points.

Physical characteristics. 1. Depth of knowledge and deepening of understanding.

High School Physics. In high school physics, to deepen the understanding of important physics knowledge, some will move from qualitative discussion to quantitative calculation, such as the relationship between force and motion, the concept of kinetic energy, electromagnetic induction, nuclear energy, etc.

2 Breadth of knowledge and expansion of scope.

In high school physics, it is necessary to expand the scope of physics knowledge and learn many new contents that have not been learned in junior high school, such as the synthesis and decomposition of forces, Newton's law of universal gravitation, the theorem of momentum, the law of conservation of momentum, and the nature of light.

3. Application of knowledge and improvement of ability.

High school should not only learn physics knowledge, but more importantly, improve the ability to learn physics knowledge and apply physics knowledge.

In conclusion, high school physics is a spiral compared to junior high school physics.

There are three high school physics textbooks, of which the first and second books are compulsory, and the third book is compulsory and elective. Physics is both a national examination subject and a college entrance examination subject in most provinces, and occupies an important position in high school learning.

Knowledge points. Compulsory 1.

a) Description of the movement.

1 Content Standards.

1) Through historical facts, we will have a preliminary understanding of the background of modern experimental science and understand the role of experiments in promoting the development of physics.

Example 1 Understand Aristotle's main ideas and research methods on force and motion.

Example 2 Understand Galileo's experimental research work, and understand Galileo's scientific ideas and methods on experiments.

2) Through the understanding of the particles, understand the characteristics of physical models in physics research, and experience the role of physical models in exploring natural laws.

Example 3 Recognize the circumstances in which an object can be regarded as a particle.

3) Experience the experimental research process of linear motion with uniform velocity, understand displacement, velocity and acceleration, understand the law of linear motion with uniform velocity, and experience the role of experiment in discovering the laws of nature.

Example 4 Dotting timer, strobe photography, or other experimental methods are used to study uniform linear motion at variable speed.

Example 5 Illustrates the experimental and reasoning methods used by Galileo to study the movement of free fall through historical facts.

4) Be able to use formulas and graphs to describe linear motion with uniform variable speed, and appreciate the importance of mathematics in the study of physical problems.

For those students who talk about physics discoloration, how to eliminate fear and establish confidence in learning physics is very important, so the first lesson of physics is particularly important.

In the past, I generally wanted students to have an overall understanding of what they were going to learn in junior high school physics from the aspects of "force, heat, light, electricity, and magnetism", and the result was that the sky fell to the ground, from the ancient to the present, from the steam engine to the rocket, ......The talk was so dazzling that the children were dumbfounded! Now that I think about it, such a beginning is not only useless for students to learn physics, but also deepens the fear of physics for some students to a certain extent, causing some students to lose confidence in learning physics before they have even learned physics. Since physics is best in life, as a teacher, we should start from the most basic life phenomena, so that students can fully experience physics in life, and physics is around us, so as to dispel the idea that physics is difficult to learn, stimulate interest in learning physics, and establish confidence in learning physics.

Here's a snippet of my first lesson:

Students: From today onwards, I will study junior high school physics with you, and the knowledge of physics is both interesting and useful. In fact, physics knowledge is not unfamiliar, and students have been exposed to a lot of physics knowledge.

For example: 1. "Students, why don't you use your head to hit the wall?" "It hurts," many of the students shouted. "Well, you know the pain, and you already understand that the forces between objects are reciprocal. ”“

So, what other similar phenomena do you know of? "When rowing, paddling backwards; When rollerblading, push hard backwards; When jumping high, pushing down hard and so on, students can give many examples.

2. "After washing the school uniform, what are some ways you can make it dry faster?" As a result, the students found several methods: drying; Hang it in a sunny place; Rinse dry in a washing machine; electric iron ironing; Roasted over fire; Hang it in a ventilated place ......"It seems that the factors that affect the speed of evaporation have long been mastered by the students.

3. "When your little hand is red from the cold, what are some ways you can warm it up?"

Almost all the students moved: some rubbed their hands; There is a haw; Some put their hands under their armpits; There is a ...... that makes a fire"The students already know two ways to change the internal energy of an object – work done and heat transfer. In this way, it is difficult for students to learn physics well! ”

4. "When your dad drove you on a trip, how would you feel if you suddenly accelerated?" How does it feel if you brake suddenly? "There are basically no classmates who can't say it.

Students, this is the phenomenon of inertia that we will learn about next. It seems that you already have the foundation to learn inertia well. ”

5. "Give you a piece of chalk, how do you disconnect it?" How can the chalk on the lectern make it move? The students raised their hands to speak in a variety of ways.

Students, your method is very good and ingenious, and this is what we will study in the future: the effect of force - force can change the shape of objects.

What about physics? What are some good ways to study?

Now there are many friends, all say that for high school physics is a relatively difficult subject, which makes physics a kind of sore in the hearts of many high school students, in fact, learning high school physics is also very simple, as long as you master good ideas, cultivate your own study habits, let yourself like this subject, in fact, it is relatively simple.

High School Physics Textbook.

1. Learn more, observe more, and think more.

In fact, high school physics is about some theorems of things in nature, these are many things around us that contain these truths, there is physics everywhere in life, for example, every time we take a car, we can see the outside world and the things outside these cars are going backwards, this is the reference in our high school physics, this knowledge point, there is knowledge everywhere in life, you have to experience it with your heart.

As long as we have an eye for discovery, you must look more at the many phenomena in your life, whether it is natural or life, you also have to look at the stars at night, see their changes, you will also find light and heat in physics and some law problems. This knowledge is still present in our lives.

1. Learn to start with theorems.

You have to attach great importance to some theorems and some dead concepts and some laws, but you not only have to remember this knowledge from time to time, you have to learn how to use it, this is the key, smart children are using these formulas and then applying them to their own mistakes, from which to find the problem, you also have to do from a small mistake, you can review a lot of knowledge, it is really a double harvest, which is also the key to whether students can open up in high school physics.

Second, change the incomprehension to be very proficient.

Because there are many new concepts in high school physics, and there are also some nouns such as: potential energy, elastic potential energy, etc., you don't see these words that you haven't seen, and you don't like them, you know? As long as you have a deep understanding and look carefully, and then you look at some textbooks and some tutorial books, you can understand.

For learning, if you like this subject more, the better you will learn, maybe for various reasons to make you like this subject, maybe because of the teacher, some teachers grasp it tightly, you learn this subject very well, but some students just like this teacher and like this subject, if you change the teacher, you will not learn well, in fact, this is harmful to yourself.

High School Physics Exam Papers.

Read every textbook, read every unit, learn every problem, have key insights and solutions for every exercise in high school physics, maybe they use the same knowledge, as long as you remember a theorem you can do many similar problems.

Electromagnetism is indeed more difficult, more difficult than the analysis of force, but master the analysis method, the formula must be memorized, the textbook example questions and after-class questions should be analyzed thoroughly, and the usual exam summary Oh, it is absolutely no problem!

Take good notes in class, keep up with the exercises after class, memorize formulas, buy a good tutorial book, be good at thinking, and have more connections with life.

That's all right.

1. Learning physics is the same as learning other courses, pay attention to listening to lectures in class, preview and review in class or after class, and learn each knowledge point thoroughly. But each course has its differences: for example, I didn't take the Chinese class today, and I can make up for it tomorrow after the class, while physics is a ring after the ring, such as:

If you don't learn decimal addition and subtraction first, you won't be able to, so you must learn each knowledge point thoroughly.

2. Students are most afraid of making mistakes in the exam, and if they make mistakes, they must analyze and summarize. I summarized the four situations in which points are lost: one is that you will do it, but you are careless and do it wrong.

The second is that you can't think of how to do it for a while, and you will do it afterwards. The third is that you don't have enough time, give a little more time to think, and maybe you will do it. The fourth is that you can't do it, you can't do it if you sit there for 10,000 years.

The solution is as follows: First, be careful in the future, and be careful. Second, in the future, we must do more practice, the so-called "familiar with 300 Tang poems, can not compose poems and chant".

Three, be able to use time! Be quick! But it's fast and error-prone!

How can it be fast? There is only one way: practice more!

The fourth is the most terrifying! There are two scenarios for this. One is that you can't do it because you haven't learned it well and can't do it; Another situation is that you have learned well, but you lack the ability to draw inferences and comprehensively, and you can't do it.

Most of the students have the second problem. It makes sense for the teacher to come up with such a question. The teacher will never come up with the questions that everyone will never do, and the teacher is testing everyone's comprehensive ability.

You have to make a few more detours in your brain, think about a few more whys, and you can make it.

I wish you success in your studies! Thank you!

Sometimes the derivative of displacement is velocity, sometimes the derivative of velocity is acceleration, sometimes the definite integral of acceleration is velocity, and sometimes the definite integral of velocity is displacement.

The indefinite integral result is not the only derivative, and the verification should be able to improve the computational power of the differential calculation.

The most important thing to learn well in any course is to work hard, and as for the specific learning method, it varies from person to person. Emphasis: Don't let yourself be at the bottom of the class because it will affect your self-confidence.

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc.

It can be understood and memorized in clever ways such as visual thinking. For example, what is only a bend is a vacuum, which can be understood in this way: the vacuum is really empty, and there is no shortage of mountains and difficulties.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself that "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.
