Xiao Li Er's brows tightened together, and his eyes were firmly fixed on the two stones.

These two stones are of different sizes, and if it is common sense, it is natural that the larger one will fall first. But although this kind of thing is ordinary, no one has ever verified it, so that Xiao Li Er hesitated.

He was silent for a long time, and finally obeyed Cheng Yanjin's meaning, looked at Luo Cheng and said, "These two stones...... It should be the big one that falls first! ”

Luo Cheng smiled slightly, and secretly said in his heart, if this thing is really effective, then wait for their values to explode next. Luo Cheng didn't speak, and directly began to practice.

Bringing the two stones to chest height, under the attention of the three people, Luo Cheng let go at the same time, and the two stones fell in response, and then fell to the ground at the same time.

At this moment, there was silence all around, silent, and Xiao Li Er, including Cheng Yanjin and Chai Shao, were stunned. This is really unreasonable, shouldn't it be that heavy things fall first, how can they land at the same time?

Luo Cheng was very calm, and he didn't know these principles earlier. After all, very few people will be idle to test this, so that they will answer based on some experience.

Xiao Li Er opened his mouth, his expression was a little confused, in fact, when Luo Cheng asked him, he felt that there was a pit. But the problem is that he doesn't know what the correct answer is, so he can only guess from it.

But what he never expected was that the two stones of this size fell at the same time, which is very unreasonable, but very scientific. Xiao Li Er looked at the two stones that fell on the ground in a daze, and did not speak.

On the side, Cheng Yanjin couldn't hold back the doubts in his heart, he walked in front of Luo Cheng, picked up the two stones, and muttered: "How could it fall at the same time, could it be Brother Luo, you did it?"

Cheng Yanjin examined the two stones, but he couldn't see any problems, the weight and size of the two stones were indeed different. At this point, he could only look at Luo Cheng with doubts.

Luo Cheng was smiling, in this moment of suspicion, he had to maintain his cold and calm image. Luo Cheng said: "Did I move my hands and feet, and I will know if I bite Brother Jin and try it myself?"

Luo Cheng's performance was undoubtedly very good, so that Cheng Yanjin couldn't understand it, he weighed the two stones, and as if Luo Cheng put them on his chest, he let go in an instant.

Without accident, two stones fell to the ground at the same time, and this time Cheng Yanjin stopped talking. He can be sure that Luo Cheng really didn't do anything, so what is the reason?

Cheng Yanjin was puzzled, and the same was true of Xiao Li Er and Chai Shao. They had to set their eyes on Luo Cheng, but because their minds were in a trance, they didn't know what to ask.

They thought a lot in their minds, and according to their daily experience, it was natural that the big stone fell first. And this time, I saw with my own eyes, the two stones fell to the ground in no particular order.

They can't help but wonder, what is their so-called experience before? If those are wrong, what is the use of learning so much, they only feel that they have lived in vain from birth to now......

All in all, all three of them were a little stunned, and all they had in their minds were two stones.

In fact, this is normal, the so-called habitual experience of the three of them on weekdays was torn apart by Luo Cheng in an instant, with a confused face, their brains were full of mush, and the whole person was confused.

Seeing the reaction of the three people, Luo Cheng was slightly surprised. Speaking of which, although he had expected this, he never thought that the three of them would be in a trance like this, which made him feel a little embarrassed.

Originally, he just wanted to fool a wave of Li Shimin, but who would have thought that this would make the three of them confused. The corners of his mouth rose slightly, and he said to the three of them: "There are many strange things in the world, but you have never seen them."

Xiao Li Er came back to his senses and asked with a complicated face, "Brother Luo, what is going on?" Obviously, two stones are of different weights, how can they fall to the ground at the same time? ”

At this point, Xiao Li Er had forgotten to keep a certain distance from Luo Cheng. He kept thinking about the reason why the stones fell to the ground at the same time. Sometimes, these unpredictable things are more attractive.

Luo Cheng smiled, and said to the three of them: "Shimin, since you think that the heavy stone falls first, you can tell me how you compare."

Xiao Li Er thought for a while and said, "It's like taking a piece of paper and putting down a stone at the same time, the paper must fall slower than the stone, isn't this because the stone is heavier than the paper?"

Luo Cheng bowed his head and said: "That's a good point, but the reason why paper falls slower than stones is really not because stones are heavier than paper."

Li Shimin looked suspicious and asked, "If it wasn't for this reason, how did it happen?"

Luo Cheng put his hands behind his back and talked seriously: "First of all, you must know that it is gravity that makes the stone fall to the ground, and things will be resisted when they land."

“…… It's that the paper has more resistance than the stone, so it will fall slower than the stone...... All in all, that's it. Shimin, do you understand? Luo Cheng said earnestly.

was circled by Luo Cheng, and Xiao Li Er felt more and more confused. What Luo Cheng said, he seemed to understand a little, but he felt ignorant.

Hearing Luo Cheng's inquiry, Xiao Li Er nodded subconsciously, and Cheng Yanjin and Chai Shao also nodded. What kind of gravitational resistance did Luo Cheng just say, it seems to be very powerful......

Luo Cheng blinked, how could he not see the state of the three of them? He felt that he had become a junior high school physics teacher, and the three guys in front of him were the representatives of the poor students, and he couldn't understand such a simple thing, so he might as well go home and farm.

The three of them were still thinking, and Luo Cheng didn't interrupt, just stood quietly. He's just joking, but don't really mess with the brains of the three of them, then he can't be responsible.

After a while, Xiao Li Er first eased up, he looked at Luo Cheng, his eyes flashed, and said, "Brother Luo, I understand, this thing is really interesting."

Luo Cheng nodded slightly, giving him a teachable expression. And at this moment, Cheng Yanjin also raised his head just right, looked at Luo Cheng, and said seriously: "Regardless of the mother's gravity resistance, my old Cheng is a rough person, I don't understand, I don't understand."

The corners of Luo Cheng's mouth twitched slightly, you kid also has a strange painting style, and he is so arrogant to say that he is uneducated.

And that Chai Shao also looked at Luo Cheng, smiled bitterly, shook his head and said: "This matter is too profound, Chai Shao is dull, I really can't understand it, I don't know if Brother Luo can talk about it again?"

Luo Cheng rolled his eyes, and he was also full of emotion in his heart. You see that Chai Shao's eyes are blank now, and his face is slightly pale. At this moment, it's really scary to still think about learning!
