I made science magic

While everyone was watching, the airship began to slowly descend, and soon hovered two to three hundred meters above the square.

All the wizards in the square and the townspeople with good eyesight could see the two spheres hanging from the bottom of the airship.

The former is about one meter in diameter, made entirely of metal, and is pulled by a thick cowhide rope. The rope is so tight that it seems to be about to break at the next moment.

Although the other ball is the same size, its entire body is red and made of lighter hollow wood. The huge difference in quality between the two can be distinguished from the tightness of the cowhide rope.

Linn waited until the sea breeze gradually weakened and the airship truly hovered steadily before picking up a red flag and waving it a few times.

In the airship above, Lydia, who was lying on the edge on a stool, also quickly waved the flag in response...

"It's starting!" Linn said.

The eyes of everyone present were now focused on the two spheres suspended at the bottom of the airship.

As another wrench was pulled down by Lydia, the two ropes were almost severed...the iron ball and the wooden ball fell down at the same moment...

"The iron ball is faster, the iron ball is faster!" the young wizard shouted excitedly. Under the influence of far-sighted magic, he could clearly and accurately see that the iron ball was the iron ball at the moment the rope broke.

The one who fell first!

However, the excitement on the wizard's face was stuck in his face the next second, because after the iron ball landed, it did not surpass him in speed as he expected. Instead, it stayed very close to the wooden ball.

distance.

Rather than saying that the iron ball fell faster, it is better to explain that the rope binding the iron ball collapsed tighter, which caused it to fall a moment faster. In addition, the slight sea breeze affected the fall of the wooden ball.

Such an illusion.

Lin En was not worried from beginning to end. Compared with the mass of the two spheres themselves, the air resistance and slight breeze were almost negligible. Unless there was a sudden strong wind of level 5 or above, it would not affect the final outcome.

result.

Sure enough, until the third second, both reached the terminal velocity of their fall, and the height of the wooden ball and the iron ball were still exactly the same.

"This is impossible, this shouldn't be right!"

The wizards who saw this scene clearly had expressions of disbelief on their faces, and some even suspected that Lin En secretly applied the [Slow Falling Technique] on the iron ball to create such a surprising effect.

Just as he was thinking this, after more than twenty seconds of falling, a huge iron ball weighing two to three tons hit the square directly.

In an instant, the entire square seemed to shake. The huge impact force caused the iron ball to be deeply embedded in the sand at the moment it fell. The surrounding quicksand exploded under the force at the moment it fell, like a continuous

Grains of sand scattered in all directions like stone rain.

An invisible magic barrier surrounded the central part of the square, and the sand and stones hit the barrier continuously, making crackling sounds.

Out of trust in the great wizard, not many people paid attention to the flying sand and stones, and they all stared intently at the two balls in the center of the square.

The huge iron ball had smashed deeply into the center of the square. The displaced sand and stones formed an impact crater with a radius of about three meters, and the surrounding fine sand continued to accumulate inside.

Under the other wooden ball, the impact crater was only half a meter long and was quickly filled with sand and gravel.

Just like what Lin En said just now, two spheres with a mass difference of dozens of times crossed a distance of three hundred meters and reached the ground at the same moment!

"Professor Hellram, can you please confirm this for me?" the young wizard asked eagerly.

The great wizard did not answer, but turned to look at Lin En. Seeing him nodding, he removed the magic barrier.

The wizard immediately ran over, not minding that his ankles were stuck in the sand. He squatted down and wrapped his hands around the ball made of hollow wood, and lifted it up with all his strength.

He originally thought that this thing would be very heavy, but the result was exactly the opposite of what he expected. He just used some strength to hold the wooden ball in his arms.

"This is too light!"

The wizard said in astonishment. He roughly estimated that the wooden ball only weighed about seventy pounds, and there were no traces of magic on it.

Could it be that there is something wrong with the other iron ball?

The wizard who did not believe in evil immediately put down the wooden ball and squatted down to lift the one-meter-diameter iron ball. However, no matter how hard he tried, he could not move the ball out of the sand and gravel. In the end, he even used [

[Mage's Hand], the big iron ball is still motionless.

Hiss~ How much does this thing weigh?

The young wizard couldn't help but be speechless, and then he was sure that the other party did not cut corners.

"If anyone still has doubts, you can go up and confirm." Lin En said nonchalantly.

With Lin En's approval, the wizards and even the townspeople who had doubts about this experiment stepped into the sand one after another and used their own hands to personally test the weight difference between the two spheres.

A stronger adult can even lift the wooden ball above his head, but there is nothing he can do about the other iron ball.

In the end, Herram used [Mage's Hand] to pull the thing out of the sand, and weighed it in his hand.

"About six thousand kilograms!" Herram pondered for a moment and made a relatively accurate judgment.

Phillip, Kevin, Theodore and others looked at each other, unable to hide their shock. The dozens of times difference in mass between the two that Linn just said was too conservative. This is already close to a hundred times difference.

!

"But, it's so strange, why is this happening?" Rohr looked at Linn in confusion. He didn't care about the three gold coins he lost, but was very surprised by this phenomenon that went against common sense.

He saw with his own eyes the horrific damage caused by the iron ball when it fell to the ground, but the falling speed of this thing was exactly the same as a ball made of hollow wood.

This is not magic at all!

"Let's make a hypothesis and we'll find out." Lin En looked at the puzzled eyes in the square and added a little more tone. "According to Master Yade's theory, the falling speed of an object is directly proportional to its weight. This is not true.

Wrong?"

Rohr and others nodded. Linn changed his voice and pointed at the two spheres.

"Then if I tie the wooden ball and the iron ball together with a rope, and then throw it down from a high altitude, do you think it will fall faster or slower?"

"Of course it's faster, because the overall weight has increased..." Rolle replied without thinking.

But the next second, several wizards retorted. "No... it should be slower! The mass of the wooden ball is much lower than that of the iron ball, and the falling speed is much slower, so it will inevitably slow down the iron ball.

Falling speed.”

"If a single iron ball takes four seconds to fall and a wooden ball takes nine seconds, then if they are tied together and dropped at the same time, the final landing time should be between four and nine seconds."

Before Linn could even reply, wizards from the two groups were already quarreling together. Jonny, Alok and others were listening and felt that what both sides said seemed to make sense, but they were contradictory...

"The answer is...no change!" Lin En interrupted the quarrel.

"How could there be no change!" Philip frowned and scolded, but he paused as soon as he finished speaking, because the falling object experiment just now proved this. The falling speed of the object has nothing to do with the weight, and it will fall at the same moment no matter what.

"Mr. Rohr, can you give me a blank piece of paper?" Linn knew that many people present still had doubts, so he looked at Rohr and asked.

"Of course." Rolle took out a piece of paper from his arms and handed it to Linn, very curious about what he wanted to do.

Lin En turned to look at the townspeople, holding up the page. "Who can give me a book, as long as it is a little wider than this paper!"

Amidst the commotion, a child contributed the storybook he had brought with him.

Lin En activated the [Mage's Hand] to send the piece of paper and the storybook up to a height of two meters, and let them fall together.

The pages slowly floated in the air, and it took a full nine seconds before they fell to the ground, while the storybook fell to the ground in just three seconds.

"What are you doing?" Philip asked in confusion. Doesn't this phenomenon just refute his theory?

Linn did not answer, but gently placed the pages on top of the cover of the storybook, then raised them up in the air again with the cover facing up, and said jokingly. "Come on, guess what, now let them fall down at the same time."

, who will land first?"

"Do you still need to guess? There is no doubt that the pages are floating in the air and the book is the first to hit the ground!" Philip said decisively.

This time, both groups recognized Philip's point of view, because Lynn did not tie the two together, so they could not be regarded as a whole.

Then it must be that paper is slower and books are faster!

"Then you have to see clearly next time!" Lin En shook his head and lifted the magic directly.

The next moment, what shocked everyone present was that the paper pages did not float as everyone imagined, but just stuck to the cover of the book and fell together.

The whole process only took three seconds, and the thin paper pages and the heavy book landed at the same time!

The whole square fell into deathly silence, and they couldn't even think of why this happened.

The reality undoubtedly shattered everyone’s intuition again!

Unless...it's true as Lynn said, falling speed has nothing to do with weight!

"Did it eliminate the air resistance?" Herram said thoughtfully. Of course he could tell, because Linn pasted the paper pages on the book, so the thin paper did not need to face the resistance of the air, and of course it would follow the air resistance.

The books fell together.

Luo Er, who did not believe in evil, tried again according to Lin En's method just now, but there was still no change in the result!

Even the wizards who had the highest objections before had to consider a problem: Master Yade's theory might really be wrong!

"Your wisdom is commendable, Master Hellram! It is precisely because the books bear the air resistance instead of the pages that they will fall together!" Lin En first boasted of Hellram very naturally, and then continued

Looking at the wizards who had not yet recovered from the two falling experiments, he spoke again.

"When I was in the [Arcane Society], I once heard a master say that this world is extremely magical. Sometimes some phenomena even surpass your and my cognition. The process of wizards exploring the truth is like a few blind men trying to

By touching a dragon, you can recreate its image in your mind."

"Those who touched the legs thought the dragon was like a cylinder, and those who touched its wings thought the dragon was like a disk, flat and long... But there is no doubt that all these conclusions are one-sided!"

"Perhaps one day, another wizard will stand in this square and overturn this law of free fall with a rigorous and irrefutable experiment, but I will never be angry about it. On the contrary, I welcome anyone

Question it or prove it repeatedly through experiments!”

"Because every mistake that is corrected means that you and I are one step closer to the truth!"

Lin En's sonorous voice continued to echo in the square, and after a very brief silence, bursts of thunderous applause resounded.

Tick, Philip and others were shocked by the two free-fall experiments that were beyond their imagination, and also admired Linn's mind.

You must know that the dispute over ideas in the land of wizards is no joke. Sometimes the two schools of thought will even fight to prove whose theory is correct.

But Lin En actually did the opposite and welcomed everyone to repeatedly verify his theory through experiments. This kind of mind is really admirable!

The townspeople present also applauded together. Those knowledgeable people were sincere, but some people were confused when they heard it. A short halfling looked at Da, whose palms beside him were almost red.

Lun asked quietly.

"Do you understand what they're saying, Darren?"

"Isn't this simple? Master Yade's theory is wrong, and Mr. Lin's theory is right!" Darren had a disdainful expression on his face, but he actually felt very guilty.

He could barely get a general idea of ​​wind resistance and gravity, but he had no idea why paper and a book could fall to the ground at the same time. But since the wizards all applauded, he might as well follow suit.

wrong!

Amidst the enthusiastic applause, the huge airship slowly landed on the sand. The lively halfling girl climbed down from the airship on the ladder. When she saw everyone applauding to welcome her, her eyes narrowed with joy.

stand up.

"The Overlook's first test flight was successful. All the internal devices of the airship are normal. Captain Lydia is asking for instructions on the next step!" Lydia trotted all the way to Lin En, pretended to salute, and said very proudly.

"There are no further instructions for now, let's just get here today!" Lin En replied with a smile.

Lydia was immediately freed from the captain's state, and talked about her experience in the sky with great excitement, how she drove the airship and hit a white cloud, as well as the mountains in the distance and a glance

The endless sea...

(ps: Today it is still two in one, 4000 words. The two experiments mentioned in the article were done by Angel before he dared to write them. Although they are not as high as three hundred meters and not as heavy as an iron ball, the results are the same.

Objects with a weight difference of more than ten times will fall to the ground at the same time. As long as the mass of the object is enough, the air resistance is almost negligible, not to mention that they are all the same shape and size (don’t use table tennis balls, just try feathers, they are too light) - Finally, experiment

Find a safe place and never throw objects from high altitudes, let alone what I taught you!!)
