Rebirth of the peerless macho

Tian Hong walked to the podium and began to weigh every stone and branch carefully, with an unusually focused expression, not stopping to think.

The physics teacher stood aside and looked coldly at the biggest problem boy in the school. He didn't interrupt him. He really wanted to see what kind of tricks this problem boy had. Whether it was before or now, he hated this problem boy. , in his mind, Tian Hong is a piece of trash.

The process of thinking was long, and twenty to ten minutes had passed. Tian Hong weighed more than ten stones and miscellaneous trees.

Finally, Tian Hong began to arrange, and the branches and small stones fell one by one in his hands, forming an irregular oval.

"All right!"

Tian Hong put the last slightly larger stone in the middle, and heaved a long sigh of relief. The repelling formation took four to ten minutes, that is to say, the time of this physics class was occupied by him alone. up.

This is what Tian Hong has no choice. Although this small repelling array does not have high requirements for materials, it is not without requirements. Simply put, the better the materials, the shorter the deployment time. It takes much more time to choose stones and twigs to form a defense formation than to choose materials.

The stone and wood of the ancient city gates were all carefully selected, each stone was polished, and each piece of wood was trimmed. It is conceivable how powerful the repelling array arranged at the city gate was.

"Student Tian Hong, is this your perpetual motion machine?" The physics teacher mocked.

"Ha ha……"

"Ha ha……"

……

Hearing what the physics teacher said, a group of students gloated and burst into laughter.

"Dear teacher, this is just like a perpetual motion machine. It is precisely because I don't understand its principle that I hope you can solve the doubts in my heart." Tian Hong respectfully said.

"Okay, is there anything special about your so-called perpetual motion machine?" The physics teacher couldn't help feeling a little uncomfortable seeing Tian Hong's respectful expression, and put away the sarcasm.

"External forces cannot enter the elliptical circle unless the force is strong enough to destroy the circle. For example, if I drop a book from the top of the circle, the book will not fall at a vertical angle, but will slide back to the edge of the circle. around……"

Tian Hong picked up a book on the podium, raised it high above the circle, and then let go...

"Pong!"

The book fell, and when it fell to the sky above the circle, it seemed to be resisted by an invisible force, and it slid to the side. It first fell on the podium, and then fell to the ground.

There was a burst of exclamation from below the podium, especially the boy who helped Tian Hong pick up branches just now.

If everyone still thought it was magic at the beginning, the situation is quite different now. Everyone knows that no matter how advanced a magician is, they need props when performing, and cooperation needs to cooperate. But just now Tian Hong was really just An incredible thing has been done with a few stones and twigs.

The physics teacher also stared blankly at the rebel formation on the table, dumbfounded and speechless.

Everyone knows that gravity is one of the intrinsic properties of mass.Every body necessarily attracts another body.Although the nature of gravity has yet to be determined, people have long been aware of its existence and function.Objects approaching the Earth are invariably attracted towards the center of the Earth's mass.Because any object on the surface of the earth is really insignificant compared with the mass of the earth itself.

That is to say, any object close to the earth will be attracted to the earth. Generally, in the absence of external force, objects with a certain mass will fall at a near vertical angle, such as apples in an apple orchard.

Obviously, the angle at which the book falls without the influence of external force is not a vertical angle, which has violated the common sense of physics.

"Teacher, you can also try." Tian Hong reminded.

"it is good!"

The physics teacher's expression became serious. After thinking for a while, he picked up a piece of chalk. Compared with the shape of the book, although the chalk is small, it is less susceptible to external forces. After all, when the pages of the book are turned, it is easy to affect the book. The vertical angle of the drop.

Looking at the chalk in the hands of the physics teacher, the atmosphere in the classroom became inexplicably tense, and everyone's eyes fell on the physics teacher's hand.

"sand……"

With a slight inaudible friction sound, the chalk fell from the physics teacher's hand without any force, it was completely free fall.

The miracle happened again, the chalk drew a very obvious semicircle in the air, as if there was a transparent glass cover in the air.

"Crack!" The chalk slipped onto the podium and fell to the ground again.

This time, the physics teacher was completely shocked, with a pair of eyes fixed on the rebel formation on the podium.

"Can I touch it?" The physics teacher felt that his voice was a little hoarse and his throat was a little dry.

"Of course, but if I use too much force, it will collapse, unless I find materials to arrange it myself. However, as long as it is not deliberately damaged, it can last for a long, long time. As for how long, I don't know, maybe A few years, perhaps decades, or hundreds of years, or even thousands of years or tens of thousands of years..."

The physics teacher stretched out his hands cautiously, and gently stroked the oval circle. He felt that his hands were touching a transparent barrier, which felt very soft. With a little force, his hands could not enter at all. .

miracle!

miracle!

The shock on the physics teacher's face turned into horror. He tried to move the stones and branches with his hands, but the stones and branches stuck to the podium as if they had taken root.

"Teacher, as long as you don't destroy it, the stone, the branch, and the podium will form a whole, and you can shake the podium."

The physics teacher shook the podium cautiously.

Sure enough, those stones and branches did not slide, as if they were fixed by glue.

"How do you get in touch with this kind of force?" The physics teacher controlled his frantically beating heartbeat, looked at Tian Hong, and the trace of ridicule at the beginning had long since disappeared, replaced by awe.

In this world, no matter who does what Tian Hong does, he can gain enough respect. This has broken the laws of nature and the laws of physics.

"It's simple."

Under dozens of pairs of gazes, Tian Hong bent a finger and slowly inserted it into the transparent barrier. Then, with a light flick, a small stone bounced.

"Now, its power is gone."

"Really?" The physics teacher touched the imaginary barrier with a disbelieving expression on his face. Sure enough, the barrier disappeared, and his hand could drive straight into the stone.

There was an eerie silence in the classroom, and people were unaware of the bell for the end of get out of class.
