How can physical choices be correct and high

Let's look at the question first, is it a single factor or a double factor? Is it qualitative or quantitative? Multiple-choice questions often set "traps" to mislead you.

To ensure that the selection is correct, you can only rely on the concept to understand thoroughly, the theorems and laws are familiar, the operation is not wrong, the drawing and formula can be simplified, the calculation can be without units, in order to save time, the multiple-choice question must be correct to choose, and the score must be guaranteed.

Try to choose as little as possible, if you choose less, you will be deducted points, and if you choose more, you will be deducted all points.

In physics, it is good to be familiar with the concepts and do more relevant test questions, which is very effective!!

Find a notebook to record the questions you missed before and analyze them, so that you can ensure that you don't make mistakes in the future.

1. Connect with real life.

2. Solid basic knowledge, most of the multiple-choice questions are based on basic knowledge.

3. Remember the knowledge of the details and wish you a good score!

Let's talk about indefinite choices......

If you look at it carefully, there are generally 2+ correct options, which means that most of the questions have 2 or more possibilities or 2 or more processes.

Think about it more comprehensively, and there won't be a big problem.

High school physics, there are many multiple-choice questions, as long as one of the multiple-choice answers is wrong, the question will be thrown in vain, and the score of one question is very high. If you don't dare to be sure, it is recommended to pick a positive choice, so that you can get half of the score.

Use the elimination method to eliminate what you are sure of, and if you really can't do it, try your luck, and the best thing is to listen to the lecture well.

It's not gambling, it's not lucky, the only way is to attend classes and listen to lectures, and check the calculation formula a few times.

Physics: Comprehend more, calculate more problems, and master the rules. Some conceptual things are just rote memorization. It's okay to do more math.

Biology: Read more books, memorize what you should memorize, don't put off accounts, and turn over more books if you have nothing to do.

Chemistry: Equation !! There are still things that should be memorized, and you have to memorize more, and you have nothing to do to flip through the book, and look at the notes

That's my approach, and a lot of it works, even though I'm only in my first year of high school...

I can't give you any good idea of this. Let's talk about biology and chemistry first, and I usually get one or two wrong in multiple choice questions. Let's talk about physics, I used to have some unsure options when I was multiple-selecting.

Normally, I struggle with this. Because I can't be sure that it's completely correct, and I can't get positive wrong information (especially for some logical meaning understanding, the questioner is simply physically and mentally abnormal, and some text comprehension is prone to comprehension deviations, and these teachers don't give a correct definition of it, hey, depressed). For such situations, I generally think more and then affirm, trusting my own judgment.

Later, I found that I would not be wrong in physics multiple-choice questions (including multiple choice), so I felt that it was easier to multiple-choice physics in the future (not challenging at all), and of course, there was also the phenomenon of overconfidence (but rarely), and it was generally less choice. That's how I feel about multiple-choice questions in physics. Of course, everyone is different.

I don't know how well you can do physics, and I haven't used any of the methods used to choose techniques, so I don't have any experience. I can't help you with anything.

Physics depends on how much you comprehend. The two most important aspects of the comprehensive examination are the accuracy of multiple-choice questions and the timing of the exam.

The concept should be understood, and then the calculation should be calculated one by one, and it is necessary to take it slowly, anyway, it is certain to practice more.

Read more textbooks and truly understand the meaning of each formula in order not to miss it in the multiple-choice questions. There is no need to do so many physics problems, as long as you learn well, you can learn them thoroughly, because there are only a few classic questions, repeating them back and forth, so master the basic concepts, master the classic question types, especially some ingenious methods (in fact, these methods are just some other basic knowledge) Think carefully, don't do the questions blindly. Come on!!

This can only rely on strength, if you are not sure, it is better not to choose, and you should pay attention to the skills of doing questions, to master some basic problem-solving ideas, think of what to eliminate, verify, contrast, and the last trick is to be able to be Meng, which has to rely on your own comprehension, and you can't say it in a few words.

I'm also a junior in high school. Do more questions, and your brain will become more and more flexible.

Learn to estimate. Instead of a set of formulas to calculate. It is easy to fall into the trap of the problem by failing to calculate the formula.

When I took the college entrance examination, I got a perfect score in physics. Multiple-choice questions basically do not need to be calculated, just use estimates.

Physics is very interesting, you just need to simulate the whole physical process in your mind, and you actually have a general direction of the result, that is, qualitative analysis. This is enough to use the elimination method to filter out the answers.

Of course, if you want to do this, you need to use this method more often when you are doing problems. Simulate the entire physical process in your mind, and then use formulas to know the relationship between various physical quantities, and try to avoid multiple-choice questions for formula calculations.

Skill comes from practice. I remember when I was doing physics problems, my classmates brought them to me, and he couldn't figure it out for a long time, so I glanced at the questions and told him the answer directly, but they didn't know how I knew, and thought that I had memorized the questions too much. In fact, it is a grasp and analysis of the entire physical process.

For physics multiple-choice questions.

1.Choose the one you are sure of You should believe in your first feeling, and if you feel that the other answers are correct after answering a question, you should be careful not to change them.

2.If you are not sure about the multiple-choice question, do not choose one, and do not require you to choose all but to choose the right one

Just find the speed; Uniform use of M s on the line;

The velocity of A is 10800 60 = 180m s, and the velocity of B is 72 3 = 24m s

C's velocity is 100 24 which is approximately 5 m s

So A is the fastest, C is the slowest: A

**It's a little blurry and can't see clearly.

b, d。

3.The elastic force of all three people is equal to manpower, because the elastic force of the spring depends on the deformation length, f=kx, and the longer the arm, the greater the elastic force.

4.The balance reading remains the same, because the balance is measured with weights, and the gravitational acceleration of the weight and the measured object on the moon has become smaller, so it is still the same reading, and the spring dynamometer is measured with elastic force, and the elastic force has not changed, and the gravitational acceleration has changed, so the reading has become smaller.

The first one has already been answered by netizens, so I won't do it anymore.

2., b, d look.

Options: 3d 4d, ac should be less rigorous 5a 6b 7a
