Chapter 170

"Compared with the free fall movement after falling, there is another phenomenon that deserves our attention."

On the flat ground, Zeng Gucheng is doing popular science to Lin Li and other non physics camp leaders:

"That is, when the table tennis ball first appeared from the storage bag, it was in an absolute stillness defined by the ground as the coordinate axis."

It seems that Lin Li and others don't understand this concept. Zeng Gucheng took up his pen and paper and drew a circle on it:

"We all know that the storage bag is different from the three types of space bags.

One is that it does not need divine thoughts, but only requires spiritual power to open, and the other is that its volume is usually only about one cubic meter.

However, no matter how small a cubic meter is, it is also about one meter from the height of its internal space.

Before opening the storage bag, Comrade Liu Ming held it with its mouth upward.

Therefore, under normal circumstances, there should be an initial velocity at the moment it is poured out, that is, the internal gravitational potential energy is converted into kinetic energy. "

As Zeng Gucheng said.

Although the space inside the storage bag is small, it is not small enough to be ignored for objects.

Even if there is no initial speed in the horizontal direction when the table tennis ball falls out of the storage bag, it should also have a weak vertical speed.

For example.

It's like an empty mineral water bottle with a soybean in it.

When the mouth of the water bottle is up, the soybean will lie at the bottom of the bottle.

When the bottle mouth is turned down and the bottle cap is unscrewed, the soybean will have gravitational potential energy at the moment when the bottle is turned over, and will immediately fall out without a support.

This gives you vertical downward kinetic energy.

From a theoretical point of view.

If the table tennis doesn't have vertical downward kinetic energy, it can't fall out of the space bag - it will always float in the space bag.

Therefore, before the table tennis ball comes out of the storage bag, it must have vertical downward kinetic energy.

No matter how small this value is, it must exist!

Therefore, the initial static state observed by Zhuo Yuanxing is definitely problematic.

Or there is an error in the instrument and equipment.

Or

The retrieval process of the storage bag is not as simple as pouring out.

The probability of the former can be excluded first.

After all, if rabbits even have problems with this basic experiment, they can go home and go to bed early.

So the possibility is only the latter.

This is a very, very important discovery.

Because according to many previous tests, rabbits have long determined that the Da Mo boundary abides by the law of conservation of energy.

Now in front of the rabbits, the kinetic energy of table tennis in the space bag disappeared immediately before the export.

So where did it go?

If there is a force to offset it, where does that force come from?

At the same time, what is the limit value of this force?

If rabbits can solve this mystery, maybe qualitative changes can occur in some fields!

For example, the reverse operation of Liu Ming's previous behavior.

Suppose a moving car has a box of cigarettes, and it has a horizontal speed with the ground as the reference frame.

In other words, if you throw it out of the window, it will not do free fall, but will draw a parabola.

But if you put it in the storage bag at this time and open the bag out of the window in a few seconds... You will find that its initial velocity in the original horizontal direction has disappeared, that is, some kinetic energy has disappeared out of thin air.

What happens when we enlarge this concept and assume that the opposing force is large enough?

Students who know more about military information should know it.

The landing of aircraft on an aircraft carrier has always been a trouble.

But if you prepare a space bag under sufficient conditions, put the carrier aircraft into the bag, return its kinetic energy to zero with the help of that force, and then take it out and put it on the splint

At that time, the enemy must have called us to hang up.

So this research is very valuable.

At the same time, different from the usual theoretical derivation, this time we can deduce the theory from the reality!

The latter is much easier, which is to tell you the answer and let you push back the idea of solving the problem.

If this magical force can be cracked, the status of the cracker in the history of physics is at least Oppenheimer's!

Then several physics bosses with some excitement restrained their impulse to write a few SCI articles on the spot and came to another open space with Lin Li and other ignorant people.

this moment.

A very strange device is built in this open space.

The main body of the device is a steel support similar to a tower crane, about 60 or 70 meters high and 45 meters wide.

This kind of device is not very difficult in terms of the current carrying capacity of rabbits. At least it is not as simple as reaching out and handing it over.

There is a platform of about nine square meters at the top of the steel support, and a special platform is placed on the ground area corresponding to the platform, some of which are similar to the weighing platform of the Libra.

At this time, Wei Qiangsheng is standing on the edge above the platform, holding the space bag that he returned to the camp with him - the rabbit.

At this time, the friar of the Wei family who has more experience than a dream is pasted with a pile of stickers, which looks like the heroine of the search officer series.

After landing on the platform, he first adjusted his standing posture, and then contacted the ground through communication equipment:

"Academician Zeng, I'm ready."

Soon, Zeng Gucheng's reply came from the headset:

"The ground equipment has been debugged. Brother Johnson, you can start."

After receiving this message, Wei Qiangsheng no longer hesitated.

He immediately input his mind into the space bag and pulled out the items in the space bag.

A moment later.

A bit of rice like brilliance flew out of the mouth of the space bag. After stagnating in the air for a few seconds, it suddenly became larger and turned into a stone with a diameter of about two meters!

The scene of object scaling didn't surprise several bosses. After all, it's not at the same level as the concept of space - of course, if it's a living creature, it's another concept.

Then the stone immediately began to fall from the sky. A few seconds later, it hit the "weighing platform" on the ground.

meanwhile.

A numerical value appears on the screen in front of Zhuo Yuanxin:

3960765J！

as everyone knows.

Ft= Δ mv，F= Δ MVT, when the contact surface is solid, the action time of both sides is very short.

Therefore, in the micro invisible time, most of the gravitational potential energy of the stone is transformed into the internal energy of the "platform".

The material of this weighing platform is made of some aviation grade flat vibration alloy. Under the transformation of polonic molecules of some kind of fluid inside, this energy is instantly transmitted to another direction in the state of maximum preservation.

Then a turbine like device began to rotate rapidly.

Click, click.

gradually.

The pointer of an ammeter began to vibrate, and then swished, firmly fixed in the middle.

Half a second later, an LED light on the command platform suddenly lit up!

Zhuo Yuanxin suddenly looked at Zeng Gucheng:

"Teacher, the electric energy is 1306821 joules, about 0.3 degrees, and the conversion rate is about 33%!"

Zeng Gucheng nodded and quickly asked another inspection team:

"Comrade Mabo, what is the in vivo data of President Johnson & Johnson?"

Ma Bo in Zeng Gucheng's mouth is Liu Qianxiang's student and assistant. He once made a brief appearance when rabbits collected enlightenment information.

At this time, Ma Bo is also carefully monitoring the data. Wen Yan immediately said:

"Academician Zeng, President Wei Qiangsheng lost about 100 kcal of energy in his body, that is, 420000 joules of energy, that is, 0.15 kwh of electricity, but the mana loss cannot be counted.

According to President Wei Qiangsheng, he can probably open the space bag more than 20 times. "

Looking at the onlookers all the time, friar Wei Fan of Gatlin with a face of "this is OK.".

Zeng Gucheng glanced at academician Pan:

It seems that you can really Kapo bug!

In fact, a long time ago, the physics group put forward a hypothesis:

If a person places a heavy object in the space bag, then stand in a very high place with the space bag and open it.

Then when the weight falls, it is equivalent to an extra section of gravitational potential energy out of thin air.

If this gravitational potential energy can be processed and converted into other energy, wouldn't it be a bug?

Yes, of course.

It's an exaggeration to say that this energy appears out of thin air.

After all, previous table tennis experiments have proved that the space bag has a certain force to offset the gravitational potential energy, but the rabbits don't know where this force comes from for the time being.

Secondly, opening the space bag is to consume the spiritual power and mind of practitioners, just like a generator needs oil to generate electricity.

The formula is almost the former + the latter = stored potential energy or kinetic energy.

It can only be said that this way of energy transformation is somewhat different.

But after removing the unknown force.

If the mana consumption of the human body is less than the value obtained from the potential energy x loss coefficient of the object, the rabbits have a difference that can be used.

In other words.

That unknown force belongs to the background category of the "server" in the Mo world. Even if it needs to consume something to offset the energy every time, it has nothing to do with the rabbits. The rabbits don't need to pay any price.

During this period, the only thing rabbits consume is spiritual power, and they can obtain multiple times of other energy (such as electric energy).

In this case, if you don't go to collect some wool from the bug in the big Mo world, is it worthy of the identity of the rabbits?
