Li Mengxi smiled happily.

Playing with the little bricks on his fingers, he suddenly raised his head and asked, "Brother, what is Lou Zhu?"

"Forehead."

"It's just a big bead with seven stars on it." Li Mengxi had no choice but to explain.

Okay, I have to get dragon balls for Xiao Bian again.

Xiao Bian asked what the dragon beads were for, and the clever Li Mengxi just said that they were for looking at something nice. If they were to summon the dragon, where could they get the dragon for Xiao Bian?

"Xiao Bian, do you think that if we put the dragon ball on the shield and we pull it, will the dragon ball move?"

"It won't move." Xiao Bian shook his head.

Little Brick hasn't seen the Dragon Ball yet, and he doesn't know what the Dragon Ball is yet, but he has already extended the theory to all Little Bricks, all things, whether it is a Dragon Ball or a monster, as long as it is an object, put it on the shield and pull it,

It won't move at first.

——

Later, Li Mengxi and his younger brother conducted more complex experiments.

This time, they pulled the shield and ran at a constant speed. The sand on it would not be scattered at all on the shield at a constant speed.

Then, as soon as it stopped suddenly, I saw the sand flying forward.

When Li Mengxi came to the sand, he asked Xiao Bian, "Xiao Bian, what we looked at just now didn't move the thing on it, but why did it fly out?"

Squatting on the ground and picking up the small bricks in the sand, he looked up at Li Mengxi, then looked down at the sand, with a look of confusion on his face.

In Xiao Bian's little mind, the concepts he had just established that were applicable to everything now conflicted.

Xiao Bian didn't say anything. He picked up the sand on the ground with his little hands and put the sand on the shield.

Then, he frowned and pulled the shield.

The moment the shield moved, the sand stayed in place and did not move with it.

"Brother, he didn't move." Xiao Bian raised his head and said.

"But, it was clear that he flew out just now?" Li Mengxi showed a puzzled expression, "Shall we try again?"

Li Mengxi once again pulled the shield and ran, and then suddenly stopped it with a stick.

The sand flew forward again and spread to the ground.

"Look, is it? Did he fly?"

Xiao Zhuan saw clearly that the sand was indeed flying.

He was even more confused. When he tried it just now, it clearly didn't fly.

Xiao Bian once again wanted to prove that he was right. He put sand on the shield and pulled the shield. The sand stayed in place for a moment. He raised his head. Xiao Bian looked at Li Mengxi, his eyes seemed to say, it didn't

Move.

Li Mengxi smiled. He didn't ask any more questions. He took his brother's little hand, didn't care about anything else, and continued to play the game of running with sand.

Pull up the shield and start running. When the speed reaches a certain level, it suddenly stops and the sand flies out.

Then, Li Mengxi deliberately repeated the motion of still pulling the shield.

Just like that, keep repeating.

Xiao Bian will probably discover the difference between these two sports modes sooner or later.

Time gradually passed, and Li Mengxi was tired from running, so he had to stop.

That's it for now, let's just wait for Xiao Zhuan to suddenly realize something in the future.

Li Mengxi, who was out of breath from running, sat on the ground with his legs crossed and rested without any image. On the side, Xiao Bian seemed to have not played enough, and ran around with the shield with undiminished interest.

The test is very simple, just run fast, suddenly stop the shield, and the sand on it will fly out with a swish.

Xiao Bian thought it was fun to fly the sand. He wanted the sand to fly farther and faster.

Li Mengxi probably didn't expect that before Xiao Bian understood the difference between the two modes of movement, he discovered something else first - the faster he ran, the farther the sand flew.

What kind of theorem is this?

——

"elder brother!"

Xiao Zhuan suddenly shouted excitedly, causing Li Mengxi to turn around.

"What's wrong?"

Little Brick, who was sweating from playing like crazy, ran over excitedly with his shield in hand.

This chapter is not over, please click on the next page to continue reading! "It's all (dou, pronounced four times, in our Henan dialect, you win, you can, and none of them, it means similar to: That's it) is wrong,"

Xiao Zhuan snapped the shield in front of Li Mengxi, "Brother, look, when I pulled it, did the shield not move?"

"You grab it and run away, the shield moves."

While talking, Xiao Zhuan demonstrated to Li Mengxi the difference between the two methods of exercise.

Li Mengxi watched his younger brother demonstrate the two situations seriously. After the younger brother finished demonstrating, his little face looked up, and his little face was full of pride.

Li Mengxi was already laughing in his heart, but he still had to pretend to be surprised and confused, "But why? Why does it stay still for a while and then fly out?"

At this point, the difficulty suddenly increases.

Next, Xiao Zhuan needs to be able to summarize two completely different phenomena into a general rule.

As expected, Xiao Bian was silent again. He scratched his head and frowned, looking like he was thinking.

After that, Xiao Bian squatted on the ground, kept throwing sand on the shield, and kept pulling the half of the shield over and over.

Li Mengxi watched quietly.

After a while, Xiao Bian raised his head and said, "Brother, do you think so? It just doesn't want to move. If it doesn't move, it won't move. If it runs fast, it just wants to run.

He doesn’t want to stop, does he?”

When Xiao Bian said this, there was doubt and confusion on his face.

Li Mengxi frowned and thought about Xiao Bian's messy language.

[When it doesn’t move, it doesn’t want to move. When it runs fast, it wants to run and doesn’t want to stop. If it stops, it will fly out.]

To put it more precisely, a stationary object has a tendency to remain stationary, and a moving object has a tendency to remain in motion.

Looking at his younger brother, Li Mengxi smiled brightly and said, "Xiao Brick, do you want to say that it was originally moving, but if you let it stop, it still wants to move? It was originally stationary, but if you let it move, it still wants to stop in the same place.

Is it this way?"

Xiao Brick nodded vigorously.

Li Mengxi laughed.

"Little Brick, my brother is asking you, if we run to the left and suddenly stop, where will the sand fly?"

"Didn't the sand fly out?"

"Yes, it's flying. Where are you flying to?"

Little Brick scratched his head.

After that, Li Mengxi got up and started running again with his brother dragging the shield.

Run to the left, stop suddenly, and the sand on the shield flies to the left.

Run to the right, stop suddenly, and the sand will fly to the right.

Li Mengxi deliberately jogged first, then violently pulled the shield away, letting Xiao Bian see the sand on the shield, and then moved backwards.

This situation is extremely special.

From this point, continuing to generalize, it can be concluded that objects have a tendency to maintain their original state of motion.

After playing for a while, Li Mengxi asked Xiao Brick why the slow-moving sand suddenly pulled it forward, and he went backward.

Xiao Bian scratched his head and thought, "Does it want to run slowly instead of running fast?"

That's right, that's it.

Little Brick has successively understood that if something doesn't move, it doesn't want to move; if something runs, it still wants to run and doesn't want to stop; if something runs slowly, it still wants to run slowly instead of running fast.

Xiao Zhuan only understands this far. His understanding cannot be refined enough, and he does not have abstract concepts such as movement, maintenance, and original state. But he has indeed successfully understood the sudden change from stillness to movement, from movement to stillness, and from

Slow and suddenly fast, he has experimented with all these common phenomena of movement.

I don't know if it's as simple as just seeing a common phenomenon. Xiao Bian also knows that everything seems to be disobedient, and they don't want to do whatever they are told to do.

Whatever you ask them to do, they don't want to do it. This is the most profound and core fundamental mystery, which involves [force]. The reason why everything in the world is asked to do something, but they don't want to do it, and conversely, everything in the world doesn't want to change.

The permanent state of a state will remain unchanged if no influence is exerted. If you want to change it, you must exert influence.

"This is the first law of gravity, and from this first law, we can deduce - [force]. I seem to understand..." Li Mengxi murmured to himself, falling into deep thought.

Li Mengxi already knew the general content of gravitation. He had memorized it when he was in school. But it seemed that it was only now that he suddenly understood why this was the first law of mechanics and the law of inertia. It was so reasonable, so natural, so it was like that.
