How to Learn Physical Quantities How to Learn Physics Effectively?

Physical quantities are physical concepts that can be quantified, such as mass, velocity, acceleration, and so on. Generally speaking, in qualitative analysis, it is called a physical concept; When quantitatively analyzed, it is called a physical quantity. Not all physical concepts can be quantified, such as the concept of "matter".

In order to have a deeper understanding of the concept of "matter", people have introduced concepts such as mass, volume, density, hardness, etc., which can of course be quantified.

One of the important reasons why physics has made great progress is the introduction of physical concepts that can be quantified, thus introducing mathematics, making the study of physics precise and in-depth, and allowing the mysteries of nature to continue to be revealed to mankind.

Physics is about understanding. First, it is necessary to clarify the connection between physical concepts and laws; Second, it is necessary to closely integrate theory with the reality of life. The former is the construction of a knowledge system, and isolated knowledge is incomprehensible to humans.

The latter is a combination of theory and practice, and completely abstract theories are also incomprehensible to human beings. In a certain sense, it can be seen as a way of practice.

In a word, physical quantities, simple understanding, are the quantities used in physics: such as: velocity, angular velocity, acceleration, mass, displacement, distance, etc., as soon as you hear the teacher say physical quantities, you have to contact the questions he said or a knowledge point that involves those quantities, these quantities are physical quantities, which one is specific, depending on the specific topic!

For example, let's be honest about the topic of velocity, he said that the property of this physical quantity is the property of velocity, and this physical quantity refers to "velocity".

Physical quantities, simply put, are numbers and units that represent physical properties.

For details, you can see the page of the encyclopedia Physical Quantities. Thank you.

Construct physical knowledge into a context and framework.

Physical quantities are just a general concept.

It depends on the situation for which it is concerned.

Make each knowledge point clear.

It is natural to understand.

You're a science student.

Science students should have a scientific mindset.

So first of all, you need to know yourself. Have a relatively full understanding of your own learning ability. From a psychological point of view, learning ability generally refers to people's ability to seek knowledge, do things, and develop in a formal or informal learning environment.

From the perspective of epistemology, general learning ability refers to the ability to perform in many basic activities, such as observation, memory, abstract generalization, attention, comprehension, and so on.

Therefore, as a commonality, only people who like to learn can learn well and quickly. Although the purpose of your liking is different, you can be ready to serve the country and contribute to the people, or you can be a big official, make a fortune, and marry a beautiful wife. But you have to like it.

Only I liked it. You will learn tirelessly. And hard work is the foundation of excellence.

The specific learning method varies from person to person and from subject to subject. However, as long as we do it and often sum up experience, we can continuously improve our learning efficiency and form our own characteristics. And so, success is on the horizon.

Therefore, the best way is to keep trying, keep summarizing, and keep improving.

One word: love (physics).

Two words: diligence.

Three words: can speak (can explain physical phenomena, explain the truth to others and understand it).

Four words: draw inferences from one case (integrate and comprehend, one question with multiple solutions, and multiple questions in one type).

For physical knowledge (concepts and laws), it is necessary to remember, speak, and use (know the scope of application of concepts and laws).

The second is to be familiar with the basic questions (which can make the concepts and rules handy), and the mid-range questions to be done well (there are not many questions, but each question must be rewarded.) Commonly used to solve multiple solutions to one problem).

College entrance examination questions, do it all.

Contest questions. Take a look. Especially the competition for the first and second year of high school.

I think the best way to improve your physics score is to do more experiments on what you have learned, and deepen your learning in the experiments.

Physics is an experimental science, and the interest generated by the experimental process can change a person's career orientation, and the results produced are far-reaching.

If you want to get a high score, it's important to get an interest in learning physics.

Make up your mind, do more questions, summarize the methods by yourself, understand yourself, and have a sense of achievement, and you will learn better and better.

First of all, you must not be averse to physics, but cultivate your interest in learning physics. After all, interest is the best teacher.

Secondly, we should be good at summarizing and summarizing each chapter. So as to gain new knowledge.

Third, be good at observing the various physical situations around you. For example, many facilities in amusement parks have physical scenarios in them. Paying attention to observation helps to improve one's thinking.

You don't need to do too many questions, if you do too much, you will have an uncontrollable resistance to physics, which will be detrimental to your future studies. Pay attention to summarizing the physical models included in each physics problem.

In junior high school electricity, the most important thing is to look carefully at the circuit diagram and see the relationship between series and parallel. The analysis of the circuit diagram generally starts from the positive electrode, like the current according to the line, there may be some difficulties at the beginning, do not rush to take it slowly, will definitely study the circuit very thoroughly.

The second is the use of publicity, distinguishing between pure resistance circuits and non-pure resistance circuits. Pure resistive circuits can use p=ui, p=i square r, p=u square r. because the electrical energy is all converted into heat energyIn non-pure resistive circuits, all electrical energy is not converted into heat, so only p=ui can be used.

Pure resistance circuits generally only have resistance, while non-pure resistance circuits have small bulbs, motors, etc.

If you don't know how to communicate with the teacher in time, I believe that you will feel the joy of physics in your future physics studies. Your physics will definitely change a lot!

1 self-confidence 2 master the three "basics": basic concepts, rules, ideas 3 independent problems 4 class listening 5 notes, wrong questions 6 buy reference materials according to their own needs (don't buy more, just one book), preview in advance, don't understand the focus of the class to listen, good questions to make a mark 7 arrange time reasonably, stay up late 8 be modest, learn from others, ask more teachers 9 master the knowledge structure, after each chapter in series knowledge 10 master the necessary mathematical calculations 11 actively participate in sports activities, keep energetic, physical and mental relaxation.

What grade are you in? I'm in my first year of high school, and this is what our physics teacher summarized for us, I hope it will be helpful to you.

It is helpful to do the questions, and the more question types you have seen, the more confident you will be in the exam. However, you can't engage in the "sea of questions" tactic, you don't have to drill the knowledge points you understand, and you don't have to do more questions that you don't master very well. I can learn well at home, but I never go to tutorial classes, I don't think it's very useful.

To study physics, we must first understand the principles, second, we must do experiments, and third, we must do more problems; theory is linked with practice; physics is the foundation of science and technology, and we must not be sloppy in the slightest; we must take it seriously, study physics well, and make contributions to the cause of national defense.
