What would it be like to learn physics without it?

If you don't study physics, you will feel like a genius. Then I don't listen well to the lectures in class. Then I will use my class time to study some other subjects.

I think it will be easy for children who don't need to learn physics, because physics is very difficult, and it takes a lot of time for ordinary people to learn it.

It's going to be a very cool experience, because I have a very smart brain, and even if I don't study hard, I can know what he's like.

I just don't have to listen to lectures to do physics, I feel that physics is still very simple, just set formulas to find ideas, and it is still very easy to learn.

If you don't study physics, it's a matter of course, but it's actually pretty good. If you don't learn it, it proves that you have a high level of ability.

It will be a very refreshing experience not to study physics, because I have a very smart brain, and even if I don't study hard, I can know what he is like.

You don't need to study physics to understand everything, and the rest of the class calls me the physics god, and they will come to me as long as they don't know how to ask me.

Physics cannot be learned without learning, especially at the beginning (junior high school), many knowledge points are contrary to common sense, and it takes repeated thinking to understand. However, once you get started and learn the habits of thinking in physics, it will be much easier in the future.

It is a lack of scientific literacy, a lack of scientific knowledge in life, and it is easy to be deceived and deceived. If you have studied physics and chemistry, will you believe in water turning into oil, perpetual motion machine?

Is it possible if you don't learn?

Do you think you're Newton?

Newton honestly admitted that he stood on the shoulders of giants.

I've been thinking about science since I was a child, so I don't need to study hard every day to understand physics.

It was definitely a god-like existence in the eyes of other students. Because physics in high school alone is difficult for many people, and if you don't study physics, many people will be envious.

If you don't learn, you will definitely be a genius, and the other side of genius is a madman, and your thinking is confused!

I've never read a high school physics textbook, but I always get a perfect score on every test.

I am very responsible to say that there is nothing that can be ignored if you learn quickly.

I graduated from the Department of Physics, and the main thing in learning physics is not to solve problems, but how to discover theorems by myself!

I think you are a second-year junior high school student, and the beginning of physics in the second year of junior high school is really easy, and it will become more and more difficult in the future.

It's a dreaming experience.

If you don't learn it, it's just because you've learned it before.

What does it mean that if you don't learn, you will know everything? How do you know? Pinch your fingers and figure it out? Then please help me figure out how I can shoot the light, how I can make a fountain experiment.

Everything is natural.

There should be very few people who don't learn, right?

The difficulty of physics lies in two aspects: logical thinking and physical thinking. Life experience and hands-on skills.

The way of thinking is the main factor that determines whether physics can be learned well or not. In general, it is difficult to learn physics well in a straight line way of thinking, and when they think about problems, they consider simple or few factors, and their comprehensive expression skills are poor.

People with strong divergent thinking can associate information from one information to all aspects of information, with strong logic, strong comprehensiveness, strong language expression, and comparison or very careful. He has a strong interest in learning physics and enjoys it. Of course, it's easy to learn physics well.

The size of hands-on ability is closely related to life experience and life experience. Children who like to be hands-on and observant are easy to learn physics well, especially children who have to study and think about everything. Newton discovered the gravitational force from the phenomenon of the flat fruit falling to the ground.

Galileo discovered the isochronism of the pendulum from the phenomenon of the wind blowing the chandelier, and these examples are numerous.

The main thing is that there is no interest!

The reason why physics is not good is because there is no motivation to learn and interest in learning.

As for the method, it should also account for a certain percentage, but that is not the main reason.

Physics is relatively abstract things, not everyone's thinking understanding is so good, some people tend to memorize things, some people prefer to understand realistic texts, everyone is different, so there will definitely be some students who can't learn well, just like some students are not good at math, or English is not good, or language is not good, it is the same, it is impossible to say that a student is perfect.

Physics requires students to have a strong logical thinking ability, which is not something that can be solved with hard work. This discipline really requires a certain amount of talent.

Each has its own learning strengths. Some are not good at English, some are not good at Chinese, some are not good at mathematics, and some are not good at geography. Some of them simply can't learn the culture, but the handicraft is particularly good. Just play to your strengths.

Girls tend to be slower to learn science, especially physics and chemistry.

It's harder not to work hard enough.

The method is not right.

Physics values experimentation, and the results are more intuitive, making it easier for you to have fun.

(1) is obtained by n-mg=mv1 2 r v1=18m s by the kinetic energy theorem.

mgr-wf=1/2mv^2-0

WF = The work done by the athlete in the AB segment to overcome the frictional force is 1080J

2)v2=v1+at1

a=-μmg/m＝-5m/s^2

v2=15m/s

h=1/2gt2^2 t2=2s

x2=v2t=30m

The horizontal distance between landing site D and B is 30m

Kinetic energy theorem, proto-circumferential motion, flat throwing.

Of all the disciplines, physics is almost the most interesting and fun one. And physics is integrated into almost all other disciplines. Including philosophy.

Physics is also one of the easiest subjects to learn, which is a description and summary of the laws of nature that can be seen and touched, and can be seen everywhere.

If you feel that physics is difficult to learn, it must be due to various reasons that you don't like to play, don't like to observe the objective world, and are not interested in anything.

If you want to learn physics well, you need to cultivate curiosity and playfulness. Most physicists are very playful. Learning physics well is definitely not only about the knowledge in books, but also about the observation and exploration of the objective world.

It can be said that the knowledge in middle school physics books is just a drop in the ocean of physics as a whole.

But playing is not stupid play, it is brain-wielding play. It is a play that satisfies curiosity. Use your brain on everything and ask why.

Newton discovered gravity by asking why an apple fell to the ground, and Watt invented the steam engine by asking why the lid of a kettle was bounced on water.

In fact, as long as you pay attention to many things, you will find that many basic knowledge of physics is not learned and known, which is commonplace common sense, but it will not be accurately expressed in words, but it is not accurately described by mathematics.

When I was in the third grade of elementary school, I was curious about why the water from the water pipe could not flow continuously from top to bottom, and I found that when the water first came out of the pipe, it was continuous, but the further down it went, the thinner it became, and finally it became a droplet, and the distance between the droplets became farther and farther apart. I spent an afternoon playing with the water pipe dripping there, and I used a wooden board that moved at a constant speed to catch the water droplets, and found that although the water droplets were getting more and more spaced, the speed of the drops on the board was actually the same. The time interval between receiving water droplets is the same regardless of whether the droplets are received at a higher place or at a lower place.

At that time, I had never heard of physics, let alone gravitational acceleration, but my curiosity about water droplets led me to realize that it was a natural phenomenon for objects to fall faster and faster. Because I didn't have enough math in elementary school to describe it accurately in mathematical language, I made a bet with my classmates that the time it takes for a steel ball and a glass ball to fall to the ground is the same.

To verify, we draw horizontal lines on a wooden board, apply ink to the glass balls, weigh the wooden boards on the ground slowly, and use a ruler to push the two balls horizontally off the table and drop them on the wooden board to smash the ink. The result is on the same horizontal line, proving that the time is the same.

I started to learn physics in the second year of junior high school, acoustics and optics I learned last semester, I feel okay, the test paper of 100 in the exam can also be above 95, I will learn electricity in the next semester, and I will be forced to do it at this time, I won't know anything, I can't understand it, I won't do the questions, the exam will be thirty or forty points, and it's still Meng, no way, so I got to the third year of junior high school, I learned mechanics and functional relationships, I didn't feel anything at first, it's not difficult, it's not simple, it's probably like this, and then the physics teacher I found at home gave me one-on-one tutoring, Tutoring for two hours every weekend, counseling for about three or four months, in this process, I slowly opened up my own knowledge, including electricity, I didn't know it before, I did more and more 6 questions, to the final stage, there are basically no questions that can't, the mock test is basically wrong within 3 points, and the high school entrance examination physics full score.

Because I'm biased seriously, physics students, English scum, other subjects are average, but I enjoy high school, especially when others ask you questions, I sit in the last row at the beginning of the third year of high school, mainly because I started school late, there is no place to do, generally speaking, I feel that the last row is where poor students sit, the first exam in the third year of high school, I remember very clearly, physics is particularly difficult, the average score of physics in the whole grade is 36 points, I am directly 92 points, the teacher in class asked, is there more than 90 in our class? The whole class looked very disdainful.

My physics grades in junior high school were close to full scores. The physics score in high school is also close to a perfect score. Physics, you have to do a lot of questions.

In this way, you can consolidate your thinking. That's what I really learned. Be sure to start with simple physics questions, and work your way up to lay a good foundation at the beginning.

Then, do some more of the usual physics problems. Challenging some complex physics problems. Usually, you must do more test papers to review your knowledge.

In class, you have to listen to the lectures, and the teacher explains the test papers. And keep it safe. I'll come back at some time.

Thinking of the surprised expression in the class, I feel so good, and then more than 80 points on the fault, the second place is more than 70 points, I was the third in the physics grade, the teacher has not left me since then, and in the future, the class will not let me talk about the questions, what difficult questions I will basically do, and there are many people who ask me questions, but the whole class will not, and you will feel very cool alone.

Only if you love physics, you will learn it with your heart. I study physics and love to do physics experiments. Others think physics is difficult, but I don't think so. I fell in love with physics by doing physics experiments. Explaining the phenomena in my life with physics makes me happy
