！！！Add 30 points How to improve your analytical skills by doing physics problems???

Analytical skills: 1: You need to have a good imagination, and you need to simulate the physical process in your mind when you see the problem.

2: When you do the question, you are sure that it is a "what" question, a "what to test" question, and you need to make a review of the main knowledge tested in the question. Such as formulas, theorems.

3: Review the topic, carefully, seriously, don't take it for granted!

4: The most important thing is to do more medium or lower simple questions at ordinary times, grasp the backbone, proficient skills, do not need to deliberately, just need to do as many test papers as possible from the school, and over time you will be proficient.

In fact, most of the topics have routines, and if you are usually proficient, you can often have a general understanding when you look at it in the third year of high school.

Improving imagination is fundamental!

Imagination plays a key role, which is characteristic of the discipline of physics!

The subjects we study are only physics, with an emphasis on imagination.

I often think about some physical processes in my mind, like playing a movie. Topics should also be based on imagination. As long as this habit is formed, when you see a physics problem in the future, you will be able to practice the following in your mind.

What analysis? Imagination is the real analysis!

You must first be familiar with the knowledge in books, including basic theorems, inferences, formulas, and so on. When you see the question, you must first know what knowledge points he will test you, and then prescribe the right medicine according to the specific requirements of the question. If you see a topic without any ideas, then you have to do more questions, in fact, there are certain routines for each question, the key is that you have to be familiar with this routine, I suggest you buy a comprehensive tutorial book, do it seriously, it is best to summarize the content of each chapter, to help you sort out the key points, difficult points.

After reading a chapter, immediately do the following exercises, don't know how to read the answers, and if you don't understand again, ask the teacher. You'll be much better off with a book. Since you're almost in your third year of high school, this summer vacation is crucial.

Don't put it off until the third year of high school to make up for it, it will be too late.

If you don't want to read the answer first, you should first find a teacher or classmate, ask them about the solution, and when they explain to you, listen carefully to their explanation and write down their solution steps in your heart. When I go back, I take the time to cover the answer to the question, and I am redoing it on my own. Keep your mind clear and don't get confused when you do it.

Thinking about the problem should be considered from different angles. The main thing is to understand and understand the idea of solving the problem. Ideas are the most important.

First of all, I am a physics applicant, and I have taken the test with 136 (we have a perfect score of 150 here).

I think that reading physics depends on understanding, and the formulas and theorems in textbooks must be well understood; Practice should not only be done, but also more done, and the problem is to practice the proficiency of ideas and the use of formulas and theorems; In class, you should also listen carefully, and many of the knowledge that the teacher talks about in the textbook should be memorized, and you should read it after memorization; Finally, if you don't understand, just ask!

I think that reading physics on my own, asking for a tutor is useless, my way of reading physics is like this, I hope my method can help you, good luck!

The most important thing is to read a book, understand the concept, more or less be able to make a decision, and listen to the teacher analyze the topic. The tactics of the sea of questions will not have much effect, understanding is the first thing, and the study of physics should be combined with real life, so you don't need to blindly calculate the problem, you can make it by thinking about it. The topic should also pay attention to independent analysis and independent thinking.

Learn to use popular metaphors to understand advanced concepts.

The point was spoken upstairs. In the language of inductive points, it is necessary to establish a good physical model. It is important to know the basic concepts well.

Then, according to the conditions of the topic, a suitable physical model is established. And then use the knowledge you have learned to analyze, step by step you will find that the problem is made.

I love to do high school physics problems, I don't think it's too difficult, I don't like to always analyze on scratch paper, as superbstar2008 said, think about it in your head. Most of the physics problems in high school have to be analyzed, and you must have a clear imagination space in your mind, which is indeed like a movie, and it is very refreshing when you solve a problem correctly!

I think; Look at the questions more.

You can't just do the questions, you have to look at the questions you have done before, you have to look back at the questions you have done before

You can get some insights from it!

I'm a junior high school student, and I did well in every physics exam. Although I don't know if physics is difficult in high school, I have a principle in reading physics, which is to listen carefully to lectures. Be aware of the notes taken.

First of all, you have to like it, the important thing is to think, and the key is to do more questions.

You need to understand why the question is answered the way it is, and then practice a lot.

I would like to add one more thing to the solitary peak to break the army, it is not enough to just do more questions, but also to look at the solution ideas.

I think the most important thing is to be interested.

Summary. Seek help! Physics.

1210 ohms, r u squared divided by p

The second question, p u squared divided by the buried r, the result is 110 * 110 1210 = 10w, current, i is equal to the liquid p u, that is, 1 11a

Summary. Hello, dear, I'm glad to serve you, and please send me a physics question, I see if it will be!

Hello, dear, I'm glad to serve you, and please send me a physics question, I see if it will be!

When the bottle is the same as the upper and lower hands, the object is suspended in the water.

So when step b is implemented, the bottle is subjected to a downward force with the gravity of the stone and the pressure of the human hand, and an upward force with the buoyancy of water.

The buoyancy exerted by the water on the bottle = the density of the water * the volume of the bottle, so take the buoyancy - human hand pressure = the gravity of the stone, and then divide it, you can get the mass of the stone.

(a) Force analysis of small stones and mineral water bottles Stone gravity (the gravity of the bottle is too small, ignore) + pressure = buoyancy, the column equation can be solved.

b) The method is similar to stone gravity + iron gravity = buoyancy (bottle, stone) It should be noted that because the iron is tied to the outside, it can displace a part of the water, so the buoyancy should be increased on the basis of the first question.

I don't know how to ask again.

1.All three missiles have the same velocity.

2.From the conservation of momentum, mv-3mv=0 (m is the mass of the missile), and m:m=3 is solved

3.It can also be discussed in terms of Newtonian mechanics, but the equations listed are too complex.

Niu Er. umg=ma

0-v2 2=2as

The solution v=v is compared with 30 km h.

The f in the question is the indication when the spring scale hangs the weight.

Solution: (1) Weight gravity mg 50 N, from the data in the question, it can be seen that 0 to 3 seconds is the initial acceleration time.

58 50 5a1 is obtained from f mg ma1 so the final deceleration phase of a1 m s 2 is 13 to 19 seconds (i.e. 6 seconds time), and mg f ma2 is obtained 50 16 5a2

a2 2) the velocity is equal to the final velocity of the acceleration phase, v a1*t1 3) the displacement of the uniform speed can be found faster h v*t1 2+v*t2+v*t3 2 meters by the average velocity.

I feel that the question is wrong, 13 19 seconds, if the speed will be negative, that is, the elevator will have a downward process, which does not match the title.

1. It takes time for the ice to melt, and if the water temperature rises quickly and the ice does not melt, this phenomenon will be seen. It is an exaggeration to think that even if you put it in boiling water, you will still see ice within a few seconds, but the temperature meter must show more than 0 degrees.

2. There may be many reasons. It depends. For example, the equipment does not conduct heat, and the temperature of the heating device (not necessarily a flame) in the hall itself is less than 100 degrees. Or the heating efficiency is very low, and the heating speed is not as fast as the heat dissipation.
