My body has mutated in the manga

"Yeah, Yui."

He grabbed the girl's little hand and swayed gently, Zhengzong said in a serious voice.

"??"

"Who gave you the courage to choose physics? Memorize biology and other subjects. Chemistry is relatively more memorized. You must challenge physics."

It is also divided into arts and sciences.

Among the science subjects, you can choose one of three exams: mathematics, English, and physics, chemistry, and biology.

Yuigahama Yui and Masamune were in the same class, so naturally they were both majoring in science, but this idiot actually chose physics.

Did you know that in a certain ancient country, when the self-matching exam for the college entrance examination was launched, a bunch of candidates happily gave up on physics.

You idiot actually dares to choose physics and wants to take the physics exam.

"Wow, I can't help it. Why should girls have to be better at memorizing? I also have a problem, okay?"

Yui lowered her head in shame.

Although she wasn't angry at being treated like a fool by Masamune, Yui still felt a little uncomfortable at being so embarrassed.

"Okay, I'm a little strict. Let me teach Yui a lesson. Yui's basic knowledge is too poor. I'll go over the basic knowledge for you first. Let's talk about mechanics first."

Masamune hugged the girl tightly to calm her down.

"First of all, do you know what the conditions for force generation are?"

"After eating a full meal, the cells in the body provide energy?"

Yui-san analyzed.

"Stupid, that's biological. Physically, it has two conditions."

Masamune raised his hand and grabbed the two dumplings in front of the girl.

"There are two conditions for the generation of force. There must be two or more objects, such as my hand now, and Yui's two extremely precious big dumplings."

In order to make Yui understand, Zhengzong directly used local materials, and the girl couldn't help but tremble with Danzi leading the way.

The more you come into contact with the authentic, the harder it is to resist.

Otherwise, Miura Yuko wouldn't have been so obedient just now and just went up to mess around with Masamune in the corner.

"I know, it just needs two objects to be together."

"Yes, the second point is that there must be an interaction between the two objects. For example, if I exert force on Yui, my fingers will also receive a corresponding force, preventing me from continuing."

The authentic and demonstrative five fingers are pressed together in the palms, and the resistance of the two dumplings is very weak and soft.

"So this is ah."

Yui said in a weak voice, believing that she would never forget the conditions for the creation of this force in the rest of her life.

"Of course, sometimes the interactions do not necessarily need to be in contact with each other. For example, magnets with the same poles have a repulsive force and interact with each other, but they do not touch. This is the key point. When doing the questions You have to pay attention.”

Although the dumplings feel good. But Zheng Zong will not forget his tutoring responsibilities.

"yes."

Little cute Yui took a pen and started writing on the paper, writing down the authentic words, and then drew a circle with a red pen on the areas that did not necessarily need to be in contact with each other.

“It’s also very important to write well and have good-looking handwriting!”

Seeing that the girl's words were a bit flamboyant, Zhengzong transformed into a stern teacher and demanded directly from her.

"Ah, yes."

Yui pursed her lips a little aggrievedly, Zhengzong kept grabbing her, how could she use her strength?

"The conditions for the generation of force have been explained, so let's explain several iconic forces. The first one is elastic force. As a special force, elastic force must not only meet the conditions for the original force generation. , and there is another point, that is, elastic deformation occurs.”

Zhengzong became interested in such interesting teachings and became more and more serious.

"For example, Yui, look at my fingers now, and they start to exert force on you that are now in contact. Then they start to sink."

Zhengzong said, exerting force with his five fingers, it seemed that his fingers were buried in it.

"Look, the positions of each other have changed. My hand feels a force of resistance, and do you feel the elasticity now?"

"..."

"Yui?"

Realizing that Yui, as a student, had begun to lose focus, Masamune was dissatisfied, and the strength in his hand increased. Yui groaned and recovered.

"I, I know."

His face turned red.

This is the first time for me to experience such a unique way through Orthodox teaching.

Just a moment later, Yui knew that she needed to change clothes.

"Okay, now that you understand what elasticity is, let's take a closer look at friction. This thing is a very critical factor."

Zhengzong said with a smile.

I recalled the past experience in high school when I was disturbed by that knowledge and almost went crazy.

For example, on trains, on boats, in space, and in electric fields, everything you can imagine will appear.

It's a really bad question.

Although this kind of problem is relatively better in District 11, if you want to go to some better universities, the exam questions there are no worse than those in China.

"Morica?"

Yui looked at Masamune.

"Friction, the first is the mutual contact between objects."

As he spoke, Masamune's hand was already placed on Yui's body.

“The second is that the contact surface is not smooth.”

Adjusted an angle, together with Yui.
