A Pep rally for Five People
·············
"Fellow students, you can be said to be the best physics students in our school. This is especially true for Student Chen Yu. Although he's only in Year One, his results are the best.
Full marks!
Everyone, I believe that all of you have done the test paper and should know the difficulty of this test paper. The second place is student Zhang Yi. Your score is 61 points!”At this time, Chen Yu and four other students were sitting in a small classroom. The final exam had already ended.
This time, they were gathered here for a competition mobilization "meeting"!
The speaker was Lin Wei, the leader of the physics grade group in the third year of high school. He was 61 years old and one of the few special teachers in Pengcheng.
Aside from Chen Yu, there was also Zhang Yi, a female third-year student. Chen Yu gave her a score of 60 for her looks, and she had just passed. She had tanned skin, short hair, and a pair of dark red glasses. The first impression she gave others was that she was a female top student.
After reading her information, Chen Yu found that her figure wasn't up to standard, and she was flat-chested. However, to Chen Yu's surprise, Zhang Yi's biological ability had actually reached 91.
Chen Yu looked at the others and saw that most of them were in their 30s to 50s.
He had never seen anyone who was above 60. Even the biology teacher was only 58!
From this, it could be said that Zhang Yi had a unique talent in biology.
In fact, he had secretly asked around. Ever since high school, biology had never been unsatisfied.
He was an all-rounder, but his geography was a little balanced!
The other three were Li Zhiwei from Year Two, Zhang Qiang and Wang Meng from Year Three!
After Lin Wei finished speaking, the four people, including Zhang Yi, looked at Chen Yu as if they were looking at a monster. They knew very well how difficult the test was.
"Brother, are you even human?!" Wang Meng, who was sitting on Chen Yu's left, looked at Chen Yu and said directly!
Rolling his eyes, Chen Yu smiled bitterly and said," Of course, I'm not just a human. I'm also a man. So, brother, don't have any other thoughts about me. It's impossible between us!”
Wang Meng immediately felt awkward. The others also laughed out loud.
At this time, the word gay had already spread among the students in the school.
Although Chen Yu's meme was terrible, it was still very useful here.
Even Zhang Yi, who was expressionless just now, could not help but laugh!
Meanwhile, Lin Wei felt a little helpless. He had long heard Zhang Kaili say that Chen Yu wasn't someone to be trifled with.
Of course, he was still very reliable.
"Alright, stop fooling around. I'll explain things to you briefly. This high school physics competition is very important. If you can get the provincial second prize or above, you can get extra points in the province. The minimum is five points and the maximum is fifteen points. If you can get the national second prize or above, you can get extra points from all the universities in the country. It's very important to you. You have to know that these points don't matter to the poor students, but they are very important to you. Because he decides whether you can go to the ideal school or the ideal major in your heart.
You must know that although your scores can meet the school's cut-off score, your major is very difficult to meet. This is a special case.
In addition, if you take the route of special enrollment, then there will be additional points for the second prize in the physics competition.
Therefore, you must be careful. Originally, I wasn't supportive of Year One students participating in the competition because they had just started learning physics. However, that little pervert Chen Yu was an exception!”Lin Wei said as he looked at Chen Yu with a smile.
"Teacher Lin, you're hurting me!”Chen Yu's despicable reaction made everyone laugh again.
The others discovered that Chen Yu's junior was quite amusing. His personality was also quite interesting.
"Brother, it's okay. I'll buy you a band-aid later!”
"Don't. We've never started, so we don't have to start over!”Chen Yu said as he looked at Zhang Qiang in astonishment.
At first, the crowd didn't react in time. Soon after, everyone reacted, especially Lin Wei, who had been appeased by Chen Yu!
A piece of chalk was thrown over!
"You little brat, what are you thinking about all day long?! It's actually something unhealthy!"
"Haha ~"
·········
After the joke, Lin Wei got down to business!
"This is a book for you. There are two books in total. You have work to do this winter vacation. Other than completing your winter vacation homework, you have to do this last night. If there's anything you don't know how to do, you can just call me or look for me at home.”As he spoke, Lin Wei raised a book titled " Guide to the High School Physics Olympiad."
Chen Yu had read this book long ago.
Moreover, he had already finished the exercises inside. It was a little difficult at the beginning, but it felt like that later on.
They were all based on ordinary high school physics formulas, so they basically wouldn't go too far.
However, he was testing your comprehensive application and flexibility. Physics in reality was very complicated and needed to consider all kinds of situations.
Let me give you the simplest example.
Droplets of water fell!
He poured water downstairs and found that after falling for a while, the large amount of water would definitely scatter into many small droplets.
Many people had seen it before, but it contained a lot of physics knowledge.
First of all, the falling water was a process of energy conversion!
There was no doubt about this.
With the first entry point, it would be easy!
Anyone who had studied physics would know that nature liked to reduce energy through a series of processes.
Of course, this person who had studied physics before was really studying physics, not the kind who was just fooling around!
At this point, we can guess if this situation means that the energy after dispersing into small droplets will decrease!
Therefore, we can use a formula at this time: The surface energy of a liquid: dE= dS (where a is the surface tension coefficient), that is, the surface energy is proportional to the surface area.
However, this was not right either, because the surface area increased after dispersing into small droplets! This was obviously contradictory to reality.
Therefore, we have to study kinetic energy and potential energy.
There was a lot of knowledge involved in kinetic energy and potential energy. There was a lot of relevant knowledge in high school physics alone, and specific problems were analyzed in detail.
Therefore, most of the time, the problem of the competition is a simple scene that we see in our lives.
However, the physics knowledge contained in this scene was very huge.
It was also a test of one's basic skills and talent in physics.
The depth of physics study was always from three-dimensional to plane, then from plane to line, and then from line to point.
This also proved that physics was far more complicated and changeable than we thought. Physics was also very rare.
Many people said that mathematics was difficult, but physics was no less difficult than mathematics. In fact, it even surpassed mathematics in some aspects!
