Xueba God-level system

Niu Zihao at the door was very surprised. He sounded like a physics teacher, but how did he know his name?

Niu Zihao didn't think much of it, he opened the door and walked in.

"You are Niu Zihao, that student who scored 13 points in the monthly physics exam?" Teacher Yang asked.

"I didn't expect to score 13 points in the test. I thought it would be a single digit test this time." Niu Zihao didn't have the slightest bit of pride, but looked rather modest.

Taking out one of the many test papers, Teacher Yang held it in front of Niu Zihao, "Looking at your test scores, I think you are inflated. You can even write the simplest unit of acceleration wrong. Is s the unit of acceleration?" ?”

In question 13, you write the unit of acceleration as s, and in question 17 later, you write acceleration as s2. You have two units, so you ate the small 2 in front?

Niu Zihao lowered his head and remained silent.Let the physics teacher nag, in Niu Zihao's opinion, only the left ear goes in and the right ear goes out.

"Not angry, not angry, it's not good for the heart." Teacher Yang stroked his heartbeat and gradually calmed down.Originally, Zhao Liyang's problem-solving process just now gave him new hope for this class. He didn't expect to be disturbed by Niu Zihao like this, and the sea has turned into a mulberry field!All the good memories are gone.The same is nine years of compulsory education, why are you so good.

"You, solve this question on the blackboard, and I will pretend that nothing happened just now." Teacher Yang said calmly: "If you can't do it, hmph, together with the fact that you are late today, together. Tell your head teacher all about it and let him take care of you."

Saying that, Teacher Yang erased the answer Zhao Liyang had just written, leaving only the question.The problem is still the same as just now, but the difference is that it was done by a different person.

The classmates below are very curious, whether Niu Zihao can solve it.With such a simple test paper, I only got 13 points. It is estimated that I can't do it even if it is hung on the blackboard.Hey, there is a good show to watch now.Among the classmates below, there are many who see Niu Zihao making a fool of himself.Of course, there are also students who don't hear what's going on outside the window and only read the sage books.Seeing that classmate's seriousness in reading is no different from the ancient Confucian sages who have read a lot of books, except that what he read is not a physics book, but a novel, a martial arts novel that bravely braves the arena and fights for justice.

Taking the novel to read in the physics class, this classmate's perseverance has to be admired. If it wasn't for the physics teacher who just took the time to teach, his martial arts novel would have been thrown out of the sky long ago.

Niu Zihao looked at the title on the blackboard with a confused look on his face. Who should he tell his pain in his heart?Not only did I just get up, I ran to the campus and didn't let me sit back in my seat. I was also asked to do the questions. I haven't read it early!

Looking at the physics problem, Niu Zihao pretended to be thinking, but he was actually delaying time.At this time, one second of delay is one second.If I had known this earlier, I would not have come to class, and would have slept until noon, and the first period in the afternoon would be physical education, so what's wrong with that?To be honest, Niu Zihao still doesn't know whether the unit of acceleration is s or s2.

According to the content learned in junior high school, the unit of acceleration is undoubtedly s2.Because of the formula s2, he had never seen it before.However, the definition of velocity in high school physics has been further sublimated and expanded, adding the concept of vector.The devil knows which is the unit of speed and which is the unit of acceleration.

"Huh?" Niu Zihao glanced at the blackboard and scratched his head.

The teacher Yang next to him saw all this in his eyes and took it to heart. Is he going to start solving the problem, or is he just scratching his head?

I saw Niu Zihao wrote with chalk:

△x=

Although it is only half a formula, in Teacher Yang's eyes, it is indeed not easy.Students who scored 13 points in the test a month can know this formula, and they really have great potential for development!Could it be that Niu Zihao had stage fright in the exam for the 13 points this time, or was there another reason.This score is indeed pitifully low, and the students who are the bottom two in physics in the class are all more than 2 points higher than him.

Watching Niu Zihao write down the formula, Teacher Yang smiled brightly.

Unexpectedly, Niu Zihao did not continue to write.

"Is he stuck?" a classmate asked.

As my classmates talked a lot, I stood still.This is the principle that Niu Zihao has been adhering to since he has been studying for more than ten years.

Teacher Yang didn't clean the blackboard just now, leaving a vague mark of △x=, but he couldn't see what was behind the equal sign.

What exactly can △x be equal to, Niu Zihao began to rack his brains.This formula appeared in the textbook, but she ignored it.It should not be ignored, but not seen at all.

During physics class, Niu Zihao was sleeping.Even in the last week of the experimental class, Niu Zihao almost fell asleep in the laboratory.If the aunt with the locked door reminded him, he would probably have spent the night with those experimental instruments.

The more you think about it, the more you can't think of it.

Seeing that Niu Zihao picked up the chalk again and was about to start writing, the hearts of all the students in the class were brought to their throats.

Δx=at2.

A beautiful girl's voice sounded, making the entire classroom immediately quiet.

The students were stunned, everyone's first impression.This voice was made by Niu Zihao, when will he change his voice and become like a bitch.

Zhao Liyang really couldn't bear to see Niu Zihao making a fool of himself on the blackboard. As a tablemate, she was also obliged to tell him the correct answer.

Niu Zihao heard clearly this time, "the square of the kick", translated into English is "it2", why is this formula a bit awkward.Even Niu Zihao couldn't believe it, how could there be a symbol for the current i in the acceleration formula? Could it be that the car accelerates uniformly and then generates a current.

Teacher Yang couldn't bear to look directly at the answer that Niu Zihao wrote down, so he raised his leg and kicked Niu Zihao's ass. "Go on, don't be ashamed, your deskmate has already told you the answer, and you can still write it wrong. I really don't know how you wrote this △x. Re-do the test paper for this monthly test. The analysis is written below the questions, and the extracurricular activities in the afternoon will be handed over to my office."

"Ugh!"

Teacher Yang looked up to the sky and sighed, it's really a big forest with all kinds of birds.

"Okay, students, let's look at this question together next..."

Looking at Teacher Yang's eloquent way of teaching, Niu Zihao glanced at Zhao Liyang next to him and wanted to say something, but he just opened his mouth and swallowed it.Seeing Zhao Liyang taking notes seriously, Niu Zihao looked at her with more admiration. That feeling was more like he owed her a favor today, and if he had time in the future, he would definitely pay it back.Although Niu Zihao didn't say thank you to Zhao Liyang, he had already said it in his heart.
