Under everyone's gaze, the airship began to slowly descend and soon hovered forty meters above the square.
All the wizards in the square and the townspeople with good eyesight could see the two spheres hanging at the bottom of the airship.
The former is about half a meter in diameter and is made entirely of metal. It is pulled by a thick cowhide rope. The rope is stretched so tight that it seems like it will break at the next moment.
The other sphere was only one-third the size of the former. Even the naked eye could see the huge difference in mass between the two! Lin En waited until the sea breeze gradually weakened and the airship was truly hovering steadily before he picked up a red flag and shook it a few times.
In the airship above, Lydia, who was standing on a stool and lying on the edge, also waved her flag in response...
"Let's begin!" Lynn said.
The eyes of everyone present were now focused on the two spheres floating at the bottom of the airship.
As Lydia pulled down another wrench, the two ropes were immediately cut... Two iron balls fell at the same time...
"The big one is faster, the big one is faster!" the young wizard shouted excitedly. With the help of the farsighted magic, he could clearly and accurately see that the big iron ball fell first when the rope broke! However, the wizard's excitement was stuck on his face the next second, because after the big iron ball fell, it was not as fast as he expected, but kept a very close distance with the small iron ball.
Rather than saying that the big iron ball fell faster, it would be more accurate to explain that the rope binding the big iron ball became tighter, which caused it to fall a split second faster.
Lin En was not worried from beginning to end, because he had carefully calculated the data of the two iron balls. Although the mass of the large ball was greater, its windward surface was also larger and would be subject to more wind resistance.
Sure enough, in the second second of falling, the heights of the large and small iron balls were still almost the same.
"This is impossible, this shouldn't be right!"
The wizards who saw this scene had expressions of disbelief on their faces, and some even suspected that Lin En had secretly cast the [Slow Fall Spell] on the big iron ball, which caused such an amazing effect.
Just as he was thinking this, a huge iron ball weighing half a ton smashed directly onto the square.
In an instant, the entire square seemed to shake. The huge impact force caused the big iron ball to embed deeply into the sand at the moment of its fall. The surrounding quicksand exploded at the moment of its fall, like continuous sand and stone rain, scattering in all directions.
An invisible magic barrier surrounded the center of the entire square, and sand and stones hit the barrier, making crackling sounds.
Out of trust in the great wizard, not many people paid attention to the flying sand and stones, and everyone stared at the two spheres in the center of the square.
The heavy iron ball has smashed deeply into the center of the square, and the displaced sand and gravel have formed an impact crater with a radius of about three meters. The surrounding fine sand is still constantly accumulating inside.
Below the other small iron ball, the impact crater was only a few dozen centimeters in size and was quickly filled with sand and rocks.
Just as Lin En said just now, the two spheres with a mass difference of dozens of times crossed the distance of 40 meters and reached the ground almost at the same time...
But how is this possible? Shouldn't the heavier one hit the ground first?
"Professor Hellram, can you let me confirm this?" the young wizard asked anxiously.
The great wizard did not answer, but turned to look at Lin En. When he saw the other party nodded, he removed the magic barrier.
The wizard ran over immediately, not minding that his ankles were stuck in the sand. He squatted down and picked up the small iron ball, which was only the size of a palm, with one hand and threw it.
"It's really light!"
The wizard spoke thoughtfully, roughly estimating that the ball weighed only about twenty kilograms, and there was no trace of magic on it.
Could it be that there is something wrong with the larger iron ball?
The wizard, who didn't believe in evil, immediately put the small ball down, squatted down and tried to lift the large iron ball with a diameter of half a meter. However, no matter how hard he tried, he couldn't move it out of the sand.
Hiss~ How heavy is this thing?
The young wizard couldn't help but be amazed, and then he was sure that the other party did not cut corners.
“If anyone still has doubts, feel free to go up and confirm it.” Lin En said nonchalantly.
With Lin En's approval, wizards and even townspeople who had doubts about the experiment stepped onto the sand and used their own hands to test the weight difference between the two balls.
Just as they saw visually, the difference between the two was dozens of times, and only a few shaping wizards could lift it.
In the end, it was Hellram who used the [Hand of the Mage] to pull the thing out of the sand and weighed it in his hand.
"About half a ton!" Hellram pondered for a moment and made a relatively accurate judgment.
Philip, Kevin, Theodore and the others looked at each other, unable to hide their shock. What Lin En had just said about the difference in quality between the two being dozens of times was too conservative. This was already a full 25 times difference! "But, it's so strange, why is it like this?" Luo Er looked at Lin En in confusion. He didn't care about the three gold coins he lost, but was very surprised by this phenomenon that violated common sense.
He saw with his own eyes the horrific damage caused by the big iron ball when it fell to the ground. One can imagine its weight, but the falling speed of the two iron balls was exactly the same.
This isn't magic at all! "Let's make an assumption and we'll know." Lin En looked at the puzzled eyes in the square and raised his voice. "According to Master Yade's theory, the falling speed of an object is proportional to its weight. Isn't that right?"
Luo Er and others nodded, and Lin En changed the subject, pointing at the two spheres and spoke.
"If I tie this small iron ball and the big iron ball together with a rope and then drop them from a high altitude, do you think it will fall faster or slower?"
But the next second, several wizards objected. "No... it should be slower! The mass of the small ball is much lower than that of the big ball, and its falling speed is also much slower, so it will definitely slow down the falling speed of the iron ball."
"If the big iron ball takes four seconds to fall and the small ball takes nine seconds, then if the two are tied together and dropped at the same time, the final landing time should be between four and nine seconds."
Before Lin En even replied, the wizards from both factions had already started arguing. Johnny, Alok and the others were listening and felt that what both sides said seemed to make sense, yet contradictory...
"The answer is... almost no change!" Lin En interrupted the argument.
"How could there be no change!" Philip frowned and shouted, but he paused as soon as he finished speaking, because the falling experiment just now proved that the falling speed of an object has nothing to do with its weight, at least it is far less than they expected.
"Mr. Roll, can you give me a blank piece of paper?" Lin En knew that many people present still had doubts, so he looked at Roll and asked.
"Of course." Luo Er took out a piece of paper from his arms and handed it to Lin En, very curious about what he wanted to do.
Lynn turned to look at the townspeople, holding up the paper. "Can someone give me a book that's slightly wider than this piece of paper?"
Amid the noise, a child donated the storybook he had been carrying with him.
Lin En activated the [Mage's Hand] and sent the piece of paper and the storybook to a height of two meters, letting them fall together.
The paper pages floated slowly in the air and took four full seconds to fall to the ground, while the storybook fell to the ground in just one second.
"What are you doing?" Philip asked in confusion. Doesn't this phenomenon just refute his theory?
Lin En did not answer, but gently placed the paper on top of the cover of the storybook, then sent them up into the air again with the cover facing up, and said jokingly, "Come on, guess, if we drop them at the same time now, which one will land first?"
"Do you still need to guess? There is no doubt that the paper pages were floating in the air and the book fell to the ground first!" Philip said firmly.
This time, both factions agreed with Philip's point of view, because Lynn did not tie the two together, so they could not be regarded as a whole.
Then paper must be slow and books must be fast!
“Then you’d better watch carefully next!” Lin En shook his head and lifted the magic immediately.
The next moment, what surprised everyone present was that the paper page did not float up as everyone imagined, but just stuck to the cover of the book and fell down with it.
The whole process took only a second, and the thin paper and the heavy book fell to the ground at the same time! The whole square fell into a deathly silence, and they couldn't figure out why this happened.
The reality undoubtedly shattered everyone's intuition again! Unless... it is really as Lin En said, the falling speed has little to do with weight! "Did the air resistance be eliminated?" Hellram said thoughtfully. Of course he could see that because Lin En pasted the paper pages on the book, the thin paper did not need to face the air resistance and would fall with the book.
Roll, who didn't believe in evil, tried again according to Lin's method, but the result was still the same! Even the wizards who had the highest voice of opposition before had to consider a problem. Master Yade's theory might really be wrong! "Your wisdom is commendable, Master Hellram! It is because the book replaces the paper pages to bear the air resistance that they fall together!" Lin first praised Hellram very naturally, and then looked at the wizards who had not yet recovered from the two falling experiments, and spoke again.
"When I was in the [Secret Society], I heard a master say that this world is extremely magical. Sometimes some phenomena even go beyond our cognition. The process of wizards exploring the truth is like a few blind people trying to replicate the image of a giant dragon in their minds by touching it."
"The people who touched the dragon's legs thought that the dragon was like a cylinder, and the people who touched its wings thought that 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 the law of free fall with a rigorous and irrefutable experiment, but I will never be angry about it. On the contrary, I welcome anyone to question it or repeatedly prove it through experiments!"
"Because every mistake that is corrected means you and I are one step closer to the truth!"
Lin En's loud voice continued to echo in the square. After a very brief silence, thunderous applause rang out.
Tik, Philip and others were shocked by the two free-fall experiments that were beyond their imagination, and they also admired Lynn's broad-mindedness.
You have to know that in the wizarding land, disputes over ideas are no joke. Sometimes two schools will even fight to prove whose theory is correct.
But Lynn actually did the opposite and welcomed everyone to repeatedly verify his theory through experiments. Such a broad mind is truly admirable!
The townspeople present also applauded together. Those who were knowledgeable applauded sincerely, but there were also some who were confused. A short halfling looked at Darren, whose palms were almost red from clapping, and 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 was actually very guilty.
He could still understand the general idea of wind resistance and gravity, but he had no idea why the paper and a book fell to the ground at the same time. However, since the wizards applauded, he would do the same!
Amidst warm applause, the huge airship slowly landed on the sand. The lively half-orc girl climbed down the ladder from the airship. When she saw everyone applauding and welcoming her, her eyes narrowed with joy.
"The Overlook's first test flight was successful. All the equipment inside the airship is functioning normally. Captain Lydia requests further instructions!" Lydia trotted to Lin En, saluted in a pretentious manner, and said proudly.
"There are no further instructions for now. Let's stop here for today!" Lin En replied with a smile.
Lydia immediately freed herself from the state of being a captain, and excitedly talked about her experience in the sky, how she crashed into a white cloud while driving the airship, and how there were mountains in the distance and the endless sea...
