One second to remember [New Pen Fun Pavilion] (.)

Falling from a great height, the speed is not constant, but a process of continuous acceleration.

Of course, this is only a conclusion about the form of an object that never changes.

The simplest analogy is that the same page of A4 paper, crumpled into a ball and thrown down, must be many times faster than spreading out.

The main reason for this lies in air resistance!

When an object loses its support from a height, it is affected by gravity, the gravitational component of the Earth, and falls at an accelerated rate in the direction of vertical downwards and perpendicular to the earth's surface.

In addition to gravity, falling objects are also subjected to a reaction force, which is the drag caused by the extremely fast falling object and squeezing the air.

This air resistance does not have a fixed value, but varies according to the speed of the fall.

Since this drag originates from gravity, the force index will be less than gravity and will not push the object back.

The sonic boom generated in front of the nose of a supersonic aircraft breaking through the sound barrier is actually the explosion sound produced after the air compressed by the nose reaches its peak.

The reason why parachutes and gliding wings can reduce their speed mainly depends on maximizing the force area under the same unit weight, and using the air resistance to offset the gravity from the earth as much as possible.

Therefore, the velocity of the object is not an exact value, but is controlled by the total air resistance to which the object is finally subjected.

After the team's accurate calculations, with Hu Xiaodao's weight of 159.6 catties and the impact speed of the ground net, its maximum value is only 301 kilometers per hour.

Falling from a height of 10,000 meters, if Hu Xiaodao can't take effective actions to slow down the acceleration caused by gravity, then the speed at which he finally lands is likely to exceed 400 kilometers.

This speed is undoubtedly very terrifying, even if the two large nets reach the limit and can hold people, Hu Xiaodao will be shocked by the impact force, and all the brains and internal organs will be blown apart.

Hu Xiaodao knew these catastrophic consequences, so he jumped out of the cabin, and after recovering his senses, he immediately made professional adjustments to his landing posture.

Head down, feet up, this posture can often be seen from diving.

Streamlined, the minimum force area, maintaining this posture, can definitely make the speed reach more than 500 kilometers, become a human bomb, destroy the world, blood and flesh pieces fly out of 800 meters.

The correspondence with this streamlined posture is to maximize the stretch of the body, expand the force area, and allow the body to withstand more air resistance.

On this basis, according to the direction of air resistance, the shape of the human structure, its own needs and other factors, it is also necessary to make precise and professional adjustments.

In order to meet the requirements of easy adjustment of the fall direction, the limbs can withstand the wind resistance to the maximum extent and avoid the body falling into irregular rotation and other factors.

Hu Xiaodao chose a posture with his face down, his body parallel to the ground, his five fingers spread out into palms, and his hands and legs in a half-moon shape, stretched back and up.

Although it took a lot of physical strength to complete this action, this posture of falling down in half a moon is undoubtedly the most perfect form, and there is no one.

The limbs are stretched back like wings, which can ensure the stability of the body, even if it encounters strong convective air, it is not afraid of losing control, and the body parallel to the ground can also minimize the falling speed.

After completing the adjustment of the body posture, there is only one thing left, and that is positioning.

Position your body directly above the net!

Due to the influence of the airflow of the fuselage when it was just separated from the aircraft, the landing point was deviated by dozens of meters, and the green light on the right side of the windshield in front of the helmet turned into a flashing red.

"The landing point is to the right, and you need to move to the left."

Hu Xiaodao thought to himself, carefully controlled his body, and tilted slightly to the left by about 5 to 10 degrees.

Don't dare to be too much, too much will get out of control!

The air resistance, which used to pass evenly through both sides of the body, is now broken, and most of the air suddenly rushes out from the right side of the body along the small slope of the body.

Due to the imbalance of the air flow, the resistance of the air invisibly turned into a thrust, slowly pushing Hu Xiaodao's body to the left.

After more than ten seconds, the red LED light on the right side turned to normal green, and the other three lights remained green.

Seeing that the position had been adjusted, plus the time to fall down 1,000 meters, it was nearly 4 minutes, and Hu Xiaodao finally had time to carefully look at the land under his feet.

Now a minute has passed, and the altitude has dropped to about 3,000 meters, which is almost close to the limit altitude of ordinary skydivers, and the field of view has been relatively much better.

However, looking down from this height, there is still no specific scene to be seen.

At a glance, the land with a radius of hundreds of kilometers is divided into three distinct colors.

Behind the foot is the center of the magic capital, because of the height, you can't see any prosperous scene, only the gray-black brought by the reinforced concrete after all the plants have been cleared.

In the midst of this unsightly gray-black, there were scattered spots of light, constantly flickering, like countless small light bulbs in a garbage heap.

Seeing this scene, Hu Xiaodao guessed that the source of these points of light should be the light reflected by the outer protective glass of the skyscraper under the illumination of the sun.

A palm-sized mirror, swaying in the sun, can be seen by people two or three kilometers away, and it is also common sense for a skyscraper of several hundred meters to reflect more than ten kilometers of light points.

As for why it is not eight kilometers, but more than ten kilometers, then you have to refer to the calculation method of the side length of an acute triangle.

The final landing point under Hu Xiaodao's body belongs to the suburbs outside the magic capital, which is different from the every inch of land in the city, and there are buildings everywhere.

This suburb, which is being heavily developed, is mostly a desolate earthy yellow, except for a few parts with a hint of green.

It is not difficult to see that ground is being broken here, and it will not be long before it will inevitably turn into a gray-black with towering high-rise buildings, just like the center of the magic capital in the rear.

The rest of the area is green and high-spirited, which is Hu Xiaodao's favorite color!

There are hills, big trees, and green grass, full of infinite life, silently acting as a purifier, cleaning up the pollution of urban excretion.

The wind was howling in my ears, and my skin was stiffened by the strong wind, and my height was falling rapidly.

After two minutes again, the height on the right hand is displayed as 1000 meters, and the scenery on the ground is clear at a glance.

Thousands of square meters of large nets, tens of thousands, like a crowd of ants, a long line of various vehicles lined up on the side of the road, all under the eyes of Hu Xiaodao.

In the same way, Hu Xiaodao can see the ground, and the people on the ground can also see him!

"Dig a groove, look, something has fallen from the sky."

"I'll take it, Sister Lin fell from the sky, everyone hurriedly grabbed it, and grabbed it to take home to warm the quilt."

"Mom sells batches, the palm that falls from the sky, this horse is the palm that falls from the sky!!"

Tens of thousands of people in the audience, like tens of thousands of ducks crossing the road, instantly turned the sky upside down, and the sky was turned upside down.
