"Nineteen sons, the minister understands, in the future, the minister will not make this kind of impossible thing again!"

"No, no, no, didn't I just say that this way of thinking doesn't work, but we can change the way of thinking!"

Hearing this, Win Changsheng shook his head again and again, and he smiled and said to Gong Shangzao.

"The problem of power cannot be solved, but we can reduce the consumption of power!"

"Reduce the consumption of power?"

After hearing Win Changsheng's proposal, Gong Chuan couldn't help but show a surprised expression, and he looked at Win Changsheng with a puzzled expression.

At this time, Ying Changsheng did not answer his question, but continued to open his mouth and speak.

"As for the steering difficulty?"

"Actually, this is also very easy to solve!"

"Easy to solve?"

Hearing this, Gong Yi Shangzao couldn't help but show a puzzled expression.

"Is this easy to solve?"

"Of course it's solved!"

Ying Changsheng's face was solemn, and he patted his chest and said.

Immediately, he moved on to the third question that had just been raised.

"It's too slow!"

"This speed is too slow, in fact, it is a problem with that power is too weak!"

"We can also achieve the result of increasing speed by reducing its resistance!"

"This, this minister is getting more and more incomprehensible......"

After hearing Ying Changsheng's words, Gong Lose Shangzao and the whole person were directly confused, he didn't understand, what magical methods Win Changsheng had to solve, these problems that had been bothering him.

At this time, seeing that Gong lost Shangzao and the craftsmen on the side were all puzzled, Win Changsheng didn't sell it anymore, he explained to everyone.

"As the saying goes, this force is mutual, and you should understand this truth, right?"

"The reason why this car can move forward is purely because there is a force that pushes him, and the power pushes the car forward, but where does this power disappear?"

What Ying Changsheng said, in fact, is a simple theorem of physics.

However, for these, the craftsmen on the side of Gongyi Shangzao and the craftsmen on the side don't know much about it, at this moment, they look at each other head-on, looking at Win Changsheng, and don't understand the reason.

Seeing that they were puzzled, Ying Changsheng was not ambiguous, and he directly commanded.

"Go and prepare a piece of smooth glass for Ben Gongzi!"

"No!"

Win Changsheng's voice fell, and the craftsman on the side didn't dare to slack off in the slightest, and hurriedly took a piece of glass for Win Changsheng.

Nowadays, glass can be produced on a large scale in Daqin.

Inside Xianyang Palace, glass windows have been replaced everywhere, and this thing is no longer a rare item.

At this moment, when this glass was taken over, he only saw Ying Changsheng, put the glass directly on the ground, and then instructed the craftsman to say.

"Go and get a wooden toy car for Ben Gongzi again!"

Toy cars.

Throughout the ages, there have been.

It's just that one generation is closer than the next.

In Xianyang Palace, there are a lot of gadgets for young children to play, and this kind of wooden car is a very common thing.

At this moment, after Ying Changsheng's voice fell, the craftsmen on the side did not dare to slack off in the slightest, they hurriedly took over a toy car, and then presented it to Ying Changsheng's hand.

After Ying Changsheng took the car, he immediately put the car on the ground, and then pushed the car forward with his hands!

"You see, it's on the ordinary pavement, pushing him forward!"

"As the saying goes, the effect of force is mutual, and the same force, on this ground, can exert an effect, which is like this, pushing up, a little jerky, not easy to push!"

"And why is this so?"

Win Changsheng asked rhetorically.

For a while, everyone was stunned, and they didn't understand what Ying Changsheng had just said and what it had to do with the creation of this steam car.

Just when everyone was in a state of bewilderment, the public on the side was the first to open his mouth and say.

"The minister knows!"

"The reason why this is on the ground, pushing this car, when driving, it will feel jerky, is purely because this ordinary ground is too rugged, so it will be like this!"

"Not bad!"

Hearing this, Ying Changsheng nodded, and then, Chao Gong lost and said.

"You're right, it's true!"

As he spoke, Ying Changsheng pondered for a moment and concluded.

"And the reason why it feels jerky when it is pushed is purely because there is also a force on the ground that is stopping this toy car from moving forward!"

"This force, if not called anything else, is called resistance!"

"Resistance?"

Hearing the words, listening to this unfamiliar word, for a while, everyone muttered in the bottom of their hearts.

And the public loses and makes up, but he is thoughtful, and he probably understands the truth that Win Changsheng said.

At this time, Ying Changsheng continued, took the car in his hand, put it on the glass surface, and pushed it.

I saw that Ying Changsheng was fast, pushing the wooden cart on the glass surface, pushing it around quickly, and then he continued to open his mouth and say.

"Look, isn't it much easier to push on the surface of this glass?"

"Really?"

Hearing this, Gong Yi's eyes lit up, and he immediately bowed his head.

Seeing this, the craftsmen on the side also nodded their heads in agreement, and at this time, Ying Changsheng handed the car to the side of the Gong Loser Shang, and then motioned him to give it a try.

Gong Chuan Shangzao hurriedly took the wooden car, on the ground, and on the smooth plane of the glass, after trying back and forth a few times, Gong Lose Shangzao couldn't help but look at Win Changsheng on the side, and said.

"What the Nineteenth Prince said is very true, just as the Nineteenth Prince said, this is on the glass plane, and when this car drives around, it is relatively smooth!"

"Hmm!"

Ying Changsheng nodded.

Immediately, he opened his mouth to the left and right and the people around him.

"Do you know, what is the principle here?"

"This ......"

For a moment, everyone looked at each other. 、

Even the public loser was in deep thought, not knowing how to answer the question of winning Changsheng.

Then.

Win Changsheng opened his mouth and said.

"The reason is simple!"

"Didn't I just say that!"

"On this ground, there is resistance, and the existence of resistance makes it possible to encounter friction during driving, and the greater the resistance of friction, the greater the power required!"

"And you have also seen that on the surface of this glass, he does not have so much friction, the surface of the glass is as smooth as jade, so the resistance is greatly reduced, so, when pushing, it saves a lot of effort, everyone, understand the truth, right?"

"Got it, got it!"

Hearing this, the public lost his jaw and said that he understood.
