My Identity As A Schoolmaster Has Been Exposed

"So, for the eggshell of egg No. 2, the eggshell is subjected to two forces, one to the left and the other to the right, and finally a part of it is offset. The remaining force is small, so..."

When Xu Cong talked about this, his voice paused, and the students started talking.

"So number 1 is easy to break! The static one is easy to break!"

Xu Cong, "That's right!"

The students nodded and began to digest the question.

But when everyone had no doubts, Su Rui raised his hand, Xu Cong said, "Teacher, we don't have to raise our hand in class. If there is a question, stand up and ask directly."

"Of course, the premise is when there are no other students asking questions!"

Su Rui, "This is good! I learned it!"

She stood up slowly, "I want to ask, when I usually scrambled eggs, the eggs are always broken first! Why is this?"

Su Rui's remarks started from life, and the classmates were confused. They looked one by one, looking at Su Rui and Xu Cong.

"Hahaha! The head teacher is here to tear down the stage!" a classmate murmured.

Xu Cong calmly said, "It depends on whether the egg you use, teacher, is such a parallel collision! If you are one high and one low, it will involve other forces!"

Su Rui sat down thoughtfully.

Xu Cong continued: "Is this question OK? Then let's move on to the next question!"

"We turned the eggs into three. Do you know the ones who threw the balls in the circus?"

"It's just three. There is always one in the air and the other two in the performance!"

"I'm telling you! This question is a college entrance examination question, but it has also been tested in the middle school entrance examination. If you don't know it, you will be really ashamed!"

With that said, Xu Cong wrote the question on the blackboard:

An actor is performing an acrobatic performance. How close is he to the egg in the process of throwing it away?

A.300*****.3J

C.0.3J

D.30J

Xu Cong continued: "What to choose? Who chose the right question? Give the basis. I won't talk about it next, and I will go straight to the end of get out of class."

"This question is very simple! You guys, give it some strength! I really can't go on with it! Let me rest!"

His class!

What he said, so that the students would be convinced.

Self-study is better than class boring!

The classmates seemed to have beaten up one by one. At first glance, the topic was super simple, but when they got it started, they were ambiguous when they had this choice.

"Exclude A first!"

"agree!"

"But what's next? 3? 0.3? 30? How to choose?"

"This silly one, I choose 3!"

"Yes! I also think 3 is very reliable!"

Lin Mengjiao twisted her eyebrows and thought for a while, she didn't worry about choosing, she was looking for the formula, and the formula could calculate the result.

But for a while, she hasn't found it yet. As for the better-studied classmates, they started to work on the transformation of mechanical kinetic energy and gravitational potential energy.

"Lie La Yu!" is the voice of pen and paper.

Su Rui was also very interested in this question and couldn't help but pick up paper and pen to write and draw.

Xu Cong looked at the time and then at the people. He sighed and said to them: "Class is about to end! Everyone, I've talked about it! I'm a person who doesn't like to drag the hall!"

"This question is very simple! You need to change your thinking a little bit."

Everyone, "!!!"

I always feel despised by Xu Cong!

Depend on!!!

They were aggrieved one by one.

But Xu Cong did not give a chance to refute, and said directly: "The work done by human hands on the egg should obviously be transformed into the kinetic energy of the egg. During the ascent process, the kinetic energy is transformed into gravitational potential energy. When the egg reaches its peak. , The gravitational potential energy of the egg is equivalent to the work done by the hand on the egg.

"The gravitational potential energy at the highest point is equal to mgh."

"M here to pay attention, this is the quality of the egg, about fifty or sixty grams, or 0.06kg."

"G is usually calculated by 10. As for the height, the position from the belly button to the mouth is almost the same, it is only 0.5 meters, so I don't need to say more about the answer, right?"

Everyone was very reluctant and complained, "So choose C."

Xu Cong, "Yes, so choose C."

"Of course, when you learn more, you will know that the distance the force moves is very short, almost zero, so the answer is ready to come out."

Everyone was preparing to complain. Xu Cong's second method caught everyone off guard.

too suddenly!

"Xu Cong, next time you talk about the second method, please remind us that we haven't had time to change our thinking!"

"Yeah! It's very sudden! The point is that the second method is as simple as you, and it's over before I can hear it!"

Xu Cong waved his hand and said to them: "There is no time, school will be over immediately! It's dinner! Not to mention, it's going to be delayed!"

"Don't tell me! The bell rang for the end of class, the end of get out of class! Go to the cafeteria!" Xu Cong got up and wanted to run out.

After all, it's a drier!

But think again, it's not right, is your identity a half teacher?

As a teacher, I was the first to rush out of the class, faster than my classmates, hurrying to eat?

it's not good!

"Forehead……"

And Su Rui is still in the class, okay, Xu Cong thought for a while and came back.

Su Rui got up and walked up and said a few words to him: "It's pretty good. I don't think I need to come and listen in the next class at all. I'll call Teacher Lin so that he can feel at ease and bye bye."

Xu Cong nodded, had dinner with Lin Mengjiao, and they strolled.

Xu Cong asked casually: "How are your feet?"

Lin Mengjiao asked with a smile on her face: "Are you caring about me?"

Xu Cong smiled?

Lin Mengjiao said to him, "By the way, I received a love letter from a classmate who is not a girl! It's all for you!"

Xu Cong shrugged, he didn't care about this.

"Senior year, sophomore, and third year. There are even people who ask me for your Q or WeChat."

Xu Cong heard her chattering endlessly, and immediately said, "Lin Mengjiao, so you mean to tell me it's too late to regret, right?"

Lin Mengjiao immediately said angrily: "Scared! Good you Xu Cong, look at the bowl and eat the pot! Wrong! Eat the bowl, look at the pot!"

Xu Cong sneered and said, "Then what do you mean by telling me this?"

Lin Mengjiao blushed, "I, you, I, you bully!" Xu Cong looked at Lin Mengjiao coldly.

"Forehead.……"

Lin Mengjiao suddenly became dumbfounded. She glanced at Xu Cong, and the moment her eyes met, she was instantly stunned, and started to stuck and said, "I...I didn't mean that."

"I just want to drink milk tea!"

Xu Cong, "???

Are the brain circuits of girls like this? Are you really going to drink milk tea, or are you fake? Can you talk about drinking milk tea from this incident?

Seeing Xu Cong's surprised expression, Lin Mengjiao almost punched her chest with a small fist, and said shyly, "You are a straight man!"

Xu Cong: "..."
