Chapter 109 Physics Final Theoretical Questions
When the train arrived at the station, it was already midnight.
Although it was already late at night, Yongcheng seemed extremely prosperous at this time. The street lights were on and there were still many vehicles on the road.
As the second largest city in Zhejiang Province and an important port city in China, Yongcheng is located on the southeast coast, in the middle of the China coastline, on the south wing of the Yangtze River Delta, with the Zhoushan Islands as a natural barrier to the east and Hangzhou Bay to the north. It belongs to the Wuyue culture.
It has a rich cultural heritage and a long history and culture. It is a typical Jiangnan water town and seaport city. It is the southern outlet of the Beijing-Hangzhou Grand Canal and the eastern departure port of the 'Maritime Silk Road'.
Wang Ming led everyone to gather. Compared with the curiosity and fuss of the students, Wang Ming seemed very calm. He had been to first-tier cities such as Beijing, Magic City, Yangcheng, and Pengcheng, so naturally he didn't know much about the prosperity of Yongcheng.
Reaction.
Soon, everyone boarded a bus, which was arranged by the Chinese Physics Society Competition Organizing Committee to pick up and drop off participating students. There were 400 students from various provinces and cities across the country. Their food and accommodation were unified by the organizing committee.
arrange.
The hotel we stayed in was a pretty good hotel. It was the best hotel Liu Yichen had ever stayed in. It was a star-rated hotel. The hotel here was arranged by the competition organizing committee. The participating students did not need to pay for food and accommodation. Of course, if
Going out to buy things yourself is another matter.
When we arrived at the hotel, we registered our information. Liu Yichen and Chen Ming, a student from Ludao Shuangshi Middle School, lived in the same double room. The hotel room was not small, and it was clean. The competition organizing committee was very warm, and everyone
There is a stationery bag and a small card on the bedside. The small card is a commemorative card. It has the phone number of the competition committee. If you need anything, you can contact the contact person in it. In the stationery bag, in addition to 2b pencils, signature pens, rulers, and triangles
, compasses and other common things for exams, as well as an itinerary.
The entire physics competition lasts for five days from November 3rd to November 8th. Naturally, it will not only be about solving problems. On the contrary, there are many activities during the competition, such as visiting the historical and cultural monuments of Yongcheng and appreciating the beauty of Yongcheng.
For example, the Physics Society also invites some famous physics professors and even academicians to give lectures, which were beyond the reach of high school students in the past.
The real competition actually takes place on November 7th and November 8th.
Unlike the league where the results are released a month after the exam, the finals end the exam in the morning, and the marking teachers will mark the papers immediately, and the results and awards will be ready before the closing ceremony is held in the afternoon. In addition to the awards in the afternoon,
Apart from the celebration banquet, the most exciting thing is that major famous schools come on stage to give presentations, recruit award-winning students, and recruit promising students to their ranks.
Yes, colleges and universities will gather at the finals of every National Middle School Physics Competition. They will use this stage to promote admissions and compete. By then, the venue will be filled with slogans for college promotions. This is a grand gathering for physics geniuses across the country.
The stage is also a big stage for colleges and universities. Major famous schools will show off their talents on this big stage to make students feel good and recruit students in advance.
In every National Middle School Physics Competition, the first prize winner is not afraid of not being able to go to a prestigious school, because at this time, the status of both parties is equal, and it can even be said that the students have a status advantage. As long as the students are willing, they can even directly
Sign the agreement on the spot and reach an agreement directly with the prestigious school. From then on, you will be admitted to the prestigious school and no longer need to take the college entrance examination.
After browsing the itinerary and the Yongcheng city brochure, Liu Yichen went to take a shower, washed his hair, put on his pajamas, and looked at the time on the wall. It was already three in the morning, and Chen Ming had already fallen asleep.
Liu Yichen lay on the bed, began to empty his head, and soon fell asleep.
The next day, at about 8:30, Liu Yichen woke up, washed up, and went to the hotel's breakfast room to have breakfast. The hotel's breakfast was provided with a breakfast coupon. The breakfast was very rich, so you could eat as much as you wanted.
After breakfast, they went to register the news, which was done by specialized staff.
On November 2nd, a total of 400 students from 33 teams across the country gathered in Yongcheng and completed the process of checking into the hotel and checking in. The media also came here, taking photos and photography from time to time, as a high school physics event.
All parties still attach great importance to it.
Relevant leaders from Zhejiang Province and Yongcheng came to the scene in person. During the opening ceremony, the vice chairman of the Chinese Physical Society and a director of the Ministry of Education attended the opening ceremony in person. The opening ceremony was particularly grand. The vice chairman of the Chinese Physical Society personally introduced
It discusses the founding background of the high school physics competition, its development over the years, and the honors won by the Chinese team in participating in the International Olympiad Physics Competition.
It can be said that great importance is attached to the finals of the National High School Physics Competition, and the ceremony is not without grandeur.
Finally, November 7th came. This morning was the theory competition. In the final, the full score was 400 points, including 280 points for theory and 120 points for experiment.
From the beginning of the exam, Liu Yichen's attention has been highly concentrated. He has no choice but to compete with the top physics geniuses from all over the country. He must exert all his strength to win the first prize in the country!
In the past few days, Liu Yichen attended three lectures, which shocked him greatly and gave him a sudden enlightenment. He saw the tip of the iceberg of physics and realized that the physics he had learned was actually quite good.
Superficial, it's just scratching the surface.
There is a long way to go, and there is no limit to learning. This knowledge makes him more low-key and calm. Now they are on the path of physics. In fact, they have just learned to crawl, and they can't even walk yet.
When physics reaches a certain level, it is subdivided into many fields. When different fields are explaining, professors in other fields may not be able to understand it.
The person who really starts to understand physics is not an undergraduate or a graduate student, but a doctoral student. Only after obtaining a doctorate can you have the ability to start studying physics.
But now, he is only a sophomore in high school, a newbie in his own right.
Different from the previous test papers, the theoretical part of the finals only has 7 questions, which are big questions. Compared with the provincial competition, the questions in the entire theoretical part are more comprehensive and more difficult, and the difficulty has been raised to a higher level.
Even Liu Yichen won the first place with a perfect score in the Fujian Province competition area. At this time, his speed in answering questions could not help but slow down. He was full of caution. He understood each question, combined the questions with the pictures, and used the knowledge he had learned to solve the problems.
The final questions of physics competitions like this are all proposed by national experts to ensure that no questions will appear before and there will be no identical questions.
For example, the first question is about force and motion. When four balls abcd collide, the conservation of momentum must be applied, and the conservation of momentum is divided into decomposing along the x direction and along the y direction to establish a system of equations, and then based on the conservation of energy
to create the third system of equations.
To solve a problem, I listed 20 equations, combined with analysis, and wrote a full 3 pages of answer sheets before I solved it.
The second question is about the launch of a spacecraft. It is not just circular motion, but also involves Kepler's third law. After applying various physical formulas, there are also 20 equations. The equations finally answer the desired point.
The speed calculation value.
An hour has passed since I finished the first three questions.
"Huh~~~" When Liu Yichen finished the seventh question, he couldn't help sweating on his forehead and his palms. Looking at the time, there were only five minutes left before the end of the exam.
"This question is indeed... very good!" Liu Yichen couldn't help but secretly admire him. If he were asked to give the question, he would never be able to give such a comprehensive question.
If you don't do it firmly, you won't be able to do it anymore and will be stuck.
"It seems that I am still too good. I am obviously taking a test of high school physics, but I am still struggling so hard. Sure enough, there is a way out there, and there are people out there!" Liu Yichen couldn't help but reflect on himself. If he became stronger, then he would be able to do these questions if he wanted to.
It will become much easier, instead of almost not finishing within the specified time.
"When I finish the competition and the finals, I have to study harder. I'm still just a rookie!" Liu Yichen secretly thought.
At the end of the exam, the invigilator took away the test papers. Liu Yichen took a deep breath, and then slowly exhaled a breath to relax his head. He felt that his head was a little overused.
In the past, Liu Yichen felt that the current education focused too much on exams, but after being exposed to the competition, Liu Yichen felt that it was only superficial. In fact, it is full of flexibility. If you are not flexible enough, you will not be able to solve the problems at all.
Not to mention, this kind of competition also has an experimental part, which also accounts for a large amount of points.
After taking exams in the morning, students are free in the afternoon. Students can discuss the morning questions, listen to some lectures, or communicate with other provincial and municipal teams. This competition final is also a stage for communication.
After Liu Yichen finished lunch, he went back to the dormitory to take a nap first, allowing his brain to rest and relax.
After sleeping until three o'clock, he just got up and walked around the venue. There is not so much intrigue here. Everyone is a stranger, so it is pure communication and sharing. Overall, in terms of physics, there are indeed more men.
Girls, boys make up the majority, and girls are only a minority. After all, physics is also a test of thinking and logic. For example, among the questions in the morning, there are three questions that specifically test mathematical ability. You are not given a numerical value, but you need to pass
Only by solving it mathematically can we solve it. If we don't have enough mathematical ability, we can't calculate it at all.
Of course, there are also some students who are reading and studying alone, frowning and studying the morning test questions. It is obvious that the morning questions have not been completely solved.
The learning atmosphere of the entire venue is very good. Everyone here has high enough talent and self-discipline, and there are not many high school students who are one year older than Liu Yichen.
Chapter completed!
