Another world conquest manual

"Compared with the free fall motion after descent, there is another phenomenon that actually deserves our attention."

On the ground, Zeng Gucheng was doing popular science to Lin Li and other camp leaders who were not majoring in physics:

"That is, when the table tennis ball first emerges from the storage bag, it is in a relatively stationary position defined with the ground as the coordinate axis."

As if he felt that Lin Li and others could not understand this concept, Zeng Gucheng picked up a pen and paper and drew a circle on it:

“We all know that storage bags are different from large, medium and small space bags.

Firstly, it does not require spiritual thought and only requires spiritual power to be opened, and secondly, its volume is usually only about one cubic meter.

But no matter how small a cubic meter is, the height of its internal space is still about one meter.

Before Comrade Liu Ming opened the storage bag, he held it with the mouth of the bag facing up.

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 not large, it is not so small that it can be ignored for objects.

Even if the table tennis ball does not have an initial horizontal velocity when it falls out of the storage bag, it should still have a weak vertical velocity.

To use an analogy.

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

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

When the bottle cap is opened with the bottle mouth facing down, the soybeans will have kinetic energy at the moment the bottle is turned over, and will fall out immediately without a support.

This creates vertical downward kinetic energy.

And from a theoretical perspective.

If the table tennis ball does not have vertical downward kinetic energy, it will never be able to fall out of the space bag - it will always float in the space bag.

So 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 and others is definitely problematic.

Either there is an error in the instrumentation.

Either that

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

The possibility of the former can be ruled out first.

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

So the only possibility is the latter.

This is a very, very important discovery.

Because based on many previous tests, the rabbits have long determined that the Great Mo Realm obeys the law of conservation of energy.

But now, right in front of the rabbits, the kinetic energy of the table tennis ball that was originally in the space bag suddenly disappeared in the moment before the exit.

So where did it go?

If there is some kind of force that cancels it out, where does that force come from?

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

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

For example - such as the reverse operation of Liu Ming's previous behavior.

Suppose there is a pack of cigarettes in a moving car. It has a horizontal speed with the ground as the reference system.

That is to say, if you throw it out of the window, it will not fall freely, but will draw a parabola.

But if you put it into the storage bag at this time, and then open the bag outside the window after a few seconds, you will find that its original horizontal initial speed is gone, that is, part of its kinetic energy has disappeared out of thin air.

If we enlarge this concept and assume that the opposing force is strong enough, what will happen?

Students who are relatively familiar with military information should know this.

Landing aircraft on aircraft carriers has always been a hassle.

But if you prepare a space bag under sufficient conditions, put the carrier-based aircraft into the bag and use that force to return its kinetic energy to zero, and then take it out and put it on the deck.

At that time, the enemy will probably really call us cheating.

So this research is very valuable.

At the same time, it is different from the usual theoretical derivation and practice. This time, the theory is deduced from reality!

The difficulty of the latter is much easier, which is equivalent to telling you the answer and letting you work backwards to solve the problem.

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

Then the excited physics bosses restrained their urge to write a few SCI articles on the spot, and led Lin Li and other confused people to another open space.

At this moment.

There is a very strange device set up in this open space.

The main body of the device is a steel bracket similar to a tower crane, about sixty to seventy meters high and four to five meters wide.

This kind of device is difficult given the current carrying capacity of rabbits. At least it is not something that can be done simply by 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, which is somewhat similar to a scale.

At this time, Wei Qiangsheng was standing on the upper edge of the platform, holding in his hand the space bag that had returned to the camp with him - the one belonging to the rabbits.

At this time, this monk from the Wei family, whose experience was comparable to that of Doraemon, was wearing a bunch of patches on his body, and he looked like the heroine of the Investigator series.

After landing on the platform, he first adjusted his stance, and then contacted the ground through the communication device:

"Academician Zeng, I'm ready."

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

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

After receiving this message, Wei Qiangsheng no longer hesitated.

He immediately input his spiritual thoughts into the space bag and pulled the items out of the space bag.

After a while.

A bit of light like a grain of rice flew out from the mouth of the space bag. After staying in the air for a few seconds, it suddenly enlarged and turned into a stone with a diameter of about two meters!

The scene of objects scaling did not particularly surprise the big guys. After all, this is not on the same level as the concept of space - of course, if the scaling is a living thing, it is a different concept.

Then the stone immediately began to fall from the sky, and a few seconds later it hit the 'weighing platform' heavily on the ground.

at the same time.

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

3960765J!

As everyone knows.

Ft=Δmv, F=Δmv/t. When the contact surface is solid, the interaction time between both parties is very short.

Therefore, in a slightly invisible time, a large part of the gravitational potential energy of the stone is converted into the internal energy of the 'weighing platform'.

The weighing platform is made of some kind of aviation-grade flat-vibration alloy. Under the transformation of some kind of fluid-like Polo sound molecules inside, this energy is instantly transmitted to another direction with the highest degree of preservation.

Then a turbine-like device began to rotate rapidly.

Click click click.

Gradually.

The pointer of an ammeter began to tremble, and then with a swish, it firmly fixed somewhere in the middle.

Half a second later, an LED light next to the podium suddenly brightened!

Zhuo Yuanxin suddenly looked at Zeng Gucheng:

"Teacher, the electrical energy is 1,306,821 joules, which is about 0.3 degrees of electricity, and the conversion rate is about 33%!"

Zeng Gucheng nodded and quickly asked another inspection team:

"Comrade Ma Bo, what are the internal data of President Johnson \u0026 Johnson?"

The Ma Bo mentioned by Zeng Gucheng was Liu Xiangqian's student and assistant, and he had briefly appeared when the rabbits were collecting spiritual enlightenment information.

At this time, Ma Bo was also monitoring the data carefully. Hearing this, he immediately said:

"Academician Zeng, President Wei Qiangsheng lost about 100 kcal of energy in his body, which is 420,000 joules of energy, which is 0.15 kilowatt hours of electricity, but the mana loss cannot be calculated.

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

Looking at the Gatling monk Wei Fan who was always watching on the side, he looked like "This is okay".

Zeng Gucheng couldn't help but look at each other with Academician Pan:

It seems like you can really capture bugs!

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

If a person places heavy objects in the space bag and then stands at a very high place with the space bag to open it.

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

If this gravitational potential energy could be processed and converted into other energy, wouldn't this cause a wave of bugs?

Of course.

To say that this energy appeared out of thin air would be a bit of an exaggeration.

After all, previous table tennis experiments have proven that the space bag has some power to counteract gravitational potential energy, but the rabbits are not yet clear where this force comes from.

Secondly, opening the space bag consumes the spiritual power and spiritual thoughts of the practitioner, just like a generator consumes fuel 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 conversion is somewhat different.

But after getting rid of that unknown force.

If the human body's mana consumption is less than the value derived from the object's potential energy x loss coefficient, then the rabbits have a difference that they can take advantage of.

In other words.

That unknown force belongs to the background category of the "server" in the Great Mo Realm. Even if it consumes something every time it offsets the energy, it has nothing to do with the rabbits, and the rabbits do not need to pay any price.

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

In this case, is it worthy of the status of the rabbits to not try to catch a wave of bugs in the Great Mo Realm to collect some wool?
