Urban Super Academic System

"How's it going? Senior, are you satisfied with my analysis just now?" After Wang Chen made a long speech in front of the person who just gave him the question, he finally smiled and turned around to look at the middle-aged man and said with a smile.

The middle-aged man looked shocked. He didn't expect that the student in front of him was so powerful.

Although this physics experiment is really simple for them, it is a bit difficult for a high school student.

No... it should be very difficult. After all, under the current nine-year compulsory education model, students are learning some knowledge and theories in the classroom. Regarding experiments, there is currently no student who can speak clearly and clearly like Wang Chen. of.

Wang Chen's analysis is so unbelievable. It's really difficult for a high school student to have such an organized thinking.

Some of them have also taught students in school. They know that students' thinking has always been rigid. They only know the paper solutions to the problems on the test papers. If they are asked to use the physics knowledge they have learned now, If you try some hands-on physics experiments to answer the question, they won’t be able to do it at all.

This may be related to the way they are educated in school, so for high school students, although they seem to be excellent in all aspects of learning, they are stagnant in terms of hands-on and experimental thinking.

So now I see that Wang Chen can actually explain a small physics experiment that he just used to test him, and his ideas are so well-founded that he doesn't look like a high school student who is exposed to these experiments for the first time. born.

"Classmate...which school are you from?" At this time, the teacher looked at Wang Chen in shock, with disbelief in his eyes.

Wang Chen completely broke his understanding of the thinking of contemporary students. There are still students with such clear thinking today. Could it be that some schools have changed the current teaching methods?

"City No. [-] Middle School..." Wang Chen simply answered the middle-aged man's question without any expression on his face. On the contrary, now he, Wang Chen, looked indifferent.

"City No. [-] Middle School? Is it the ordinary City No. [-] Middle School?" The man was startled at first, and then another person whispered there.

"This may be a bit simple for you, let's do another one..."

"This is a small experiment about verifying the law of conservation of momentum. I don't need you to give me measurement data on site. Just look at these conditions and briefly explain to me the steps of this experiment..." He said another One man stood up and said he didn't believe it.

So he added a little more difficulty to the experimental questions. He wanted to see how powerful Wang Chen was, and he could see through the experiment just now in one second.

Looking at this posture, they are really at odds with themselves, right? The first experiment is from some pediatric books that Wang Chen read when he was young, okay? You actually use such a thing to test yourself? I really don’t know. Are their IQs low or my IQs low?

However, this question is indeed a little more difficult than the previous one, but it still doesn't trouble Wang Chen.

"Since v1, v1/, and v2/ are all in the horizontal direction, and their vertical falling heights are all equal, their flight times are equal. If this time is used as the time unit, then the value of the horizontal range of the ball is equal to their Horizontal speed. Expressed by OP, OM and O/N respectively in the diagram you gave. So just verify: m1OP=m1OM+m2(O/N-2r).”

"However, we pay attention to the following matters when conducting experiments."

1 The ball with greater mass must be used as the incident ball (to ensure that both balls move forward after collision). Want to know why?

2. The incident ball should start to slide down from rest from the same position on the chute each time.

(3) The average position of the ball's landing point should be determined with a compass: use the smallest possible circle to enclose all the landing points, and the center of the circle is the average position of the landing point.

(4) The instruments used are: balance, scale, vernier caliper (for measuring the diameter of the ball), collision tester, carbon paper, white paper, weight, two balls with the same diameter and different masses, and compasses.

(5) If the touched ball is placed at the end of the chute without a support, then the two small balls will no longer hit the ground at the same time, but both small balls will start a horizontal throwing motion from the end of the chute, so the verification equation becomes It is: m1OP=m1OM+m2ON, and the diameters of the two small balls do not need to be measured.

"Ding dong..."

"Congratulations to the host, you have successfully solved an experimental problem related to physics using the knowledge you learned in high school textbooks, so the academic points awarded by the academic system are 100 points..."

"Congratulations to the host. In the previous first physics experiment, you answered the relevant physics experiment principles based on your personal common sense. The academic points awarded by the academic system are 50 points..."

"Congratulations to the host. You shocked everyone with your answer this time. So it can be seen that your academic skills in physics convinced them all. Therefore, I received 200 points for the academic points awarded by the academic system... …”

"Report to the host, because your current Xueba points have not reached thousands in the background operation, so the Xueba system will not display the Xueba points running the day after tomorrow for the host, but the host can query your current point balance. The system is opening the Xueba system point balance query for you..."

"The system point balance query is successful. The host's current academic point balance is 232000 points..."

Before seeing everyone's reaction, Wang Chen heard the crisp sound of the system in his ears.

"I have another experimental question here..."

"That's enough. You have finished testing him. I think everyone already knows the strength of Wang Chen. I think there is no problem at all for him to stay here and work on scientific research projects with everyone. His thinking is clear. , his ideas on dealing with problems are also very bold and novel. I think it is most appropriate for him to stay. What do you think..."

For those who tested him before, Wang Chen answered them one by one and made them speechless. Others also wanted to step forward to test Wang Chen.

However, the professor stopped him immediately. He felt that there was no need for everyone to test Wang Chen. Wang Chen had already proven his strength, so if everyone continued like this, it would only be a waste of their next research. Project time.
