If there is no gravity, it is-Mount Everest, more than 8,800 meters, how many people will be crushed to death. And the climbers from all over the world who climbed it also spent a lot of effort. So maybe you will think, if there is no gravity, isn't it much more convenient to live and climb mountains? Don't just think about convenience, the trouble is yet to come-first, take mountaineering as an example. If you lose gravity, will the mountain still be there waiting for you to climb? It will wander around. If you touch it, it will learn from the Monkey King-it will turn over 18,000 miles. If gravity is lost, people will float in the air like balloons, swinging from side to side, and everything on the ground will become balloons. Maybe you will think, now you can "stretch your hand with clothes and open your mouth with rice." Actually, not at all. If you want to eat cookies with flying chips, it will be very embarrassing. The crumbs didn't fall to the ground, but entered your nose and eyes, making it difficult for you to breathe and watch. Drinking water is more difficult. Be sure to squeeze into your mouth, if you squeeze, it will easily cause small drops of water to fly all over the sky, and you can't quench your thirst at once. If you lose gravity, you can't cook. If you can't light a fire, things will fly when you touch them, and you can only go hungry-you can't even drink the northwest wind. Because, all the air has flowed into the universe ... The second part, if there is no gravity, one day on 2 108, a loud noise suddenly appeared over the earth. After a minute of darkness, people found that we could fly. Not only humans, but also cars and street lamps can fly. Everything that should be on the surface of the earth is flying all over the sky. At this time, people suddenly realized that the earth had lost its gravity. I flew home, and everything at home floated in the air. I want to drink water. As soon as it is poured out, it will be scattered in all directions. I want to sleep. I don't know where it drifted when I was lying in bed. The more I struggle, the more trouble I have. I even hit the wall. Want to play computer, holding the mouse only to find that the host has long abandoned us; I want to invite my friends to play together, but everyone can't find their shadow. It seems that they don't know where to fly. I came to the gym in a daze, and the basketball stand was floating overhead. I picked up a basketball and jumped up gently. Haha, I can dunk! So I learned the movements of the NBA's buttoners and presented a wonderful performance for everyone. Turn around 360 degrees in the air, turn around in the air relay and accelerate the attack and ride ... I think these actions will make me perform in the NBA dunk contest, and I will definitely become "Potato III". The journey home is really not peaceful, and you may be injured by objects floating in the air everywhere. Hungry and tired, I don't know if I can eat the food in my mouth tonight. I don't know if I can sleep in the bed. I struggled to float home, but it was difficult to land at home. I'm exhausted, scratching around in the air. The joy of dunking just now is long gone. It seems that life without gravity is really hard! The third article

Time: 2065438+0565438+1 October1Location: Earth-Asia-China.

At 7: 30 in the morning-

The new year is coming! Huh? Why do you feel ventilated? Why is everything upside down? By the way, today is Global Zero Gravity Day. In order to make everyone feel like an astronaut, the United Nations takes 65438+1 October1as a weightless day every year, and this year is the first one. Really not suitable!

7: 50 a.m.—

I really feel like a superman. I can fly around the house and become a Hercules. It doesn't take much effort to lift a stupid object. It's really easy. I'm just a little confused.

8: 30 in the morning-

Enough flying, let's eat. Drink a glass of milk first, take the milk out of the flying refrigerator and open the package. As soon as it arrived, the milk flew out. Milky milk particles will float in the air and will not disperse when touched by hand. Like flubber, drinking milk has become "eating" milk particles, because milk can't be poured into the mouth at all. It's really novel.

9: 40 a.m.—

After eating for more than an hour, I still didn't eat anything. Fortunately, I bought several packs of compressed biscuits the other day. But there is a new problem. I'm lost. I can't walk from the kitchen to the living room. One moment the ceiling is under your feet, and the other moment the wall is under your feet. The sense of direction that has been applied for decades is completely inappropriate here.

12∶00AM——

It took more than two hours to find the direction. Eat something and take a nap. How to sleep? Sleeping standing or lying down seems to feel the same.

65438+ 0: 30 pm-

I took a nap and opened my eyes. Oh, no, why should I fly out of the house? There are many people outside. It seems that quite a few people accidentally "fly" out. It is broken. I can't go home. I don't even know where I've drifted. How can I come back?

……

65438+ 02 midnight-

Gravity is back! We are back in the familiar place.

Let's hurry home, but where have I drifted? Surrounded by lush forests and arched mountains, there seems to be someone in the distance ... ah! It's a savage! Have I been to Shennongjia? 20 15 February 14-

In view of the global chaos that broke out on 20 15 and 1 Zero Gravity Day, the United Nations decided to cancel Zero Gravity Day.

20 15 September 1-

The world's first zero-gravity park opened, which was deeply loved by children ... Chapter IV.

Gravity is the force produced by the earth's attraction to objects. It is because of this power that we and everything in the world can survive on this earth. In this gravity environment, people walk and work on the ground, and plants grow on the ground and thrive in the upward direction. In this environment, our life is quiet and peaceful, but let's imagine what the earth would be like without gravity. Some people will say, "If there is no gravity, people will float in the air." It is also said that "breaking the world high jump record will be a piece of cake". Indeed, without gravity, everything in the world would float in the air. If it's cooking, that dish can't be cooked well. Because there is no gravity, the food will not stay in the pot honestly. Even if it is cooked, it will take a long time to pay the price. But there's no gravity. Good. You see, if you need to work at high altitude, it will be safe and convenient without gravity. Think about that spaceship again. In the case of weightlessness, if you want to eat, you can taste delicious food in one breath. If there were no gravity in the world, it would be really wonderful. People jump around or fly around in the air like kangaroos, enjoying the vastness of the sky; Water floats in the air in the form of clouds. If you want to drink water, put your mouth together. But the fish will be miserable. They may have to move out. Huh? If there were no gravity, maybe Newton wouldn't have been hit! Science is so wonderful that even science fiction is full of fun. We should love science and be a middle school student who loves learning science. The fifth article

In life, every one of us, every object, even a humble fluff, is subject to a force, which makes all objects finally fall to the ground. This is the magic of the earth, which attracts all kinds of objects and produces a force, which is gravity. Newton's discovery proved the existence of gravity, or gravity is everywhere. Gravity is really good. Ripe apples fall, people don't have to move ladders, just bend over. However, some people complain that if someone falls from the second floor, his legs will be worn out, and if he loses gravity, what will happen to the world: cars fly in the air and cannot move; People in the air, can't; People can only swim indoors. Water is a symbol of life. Without gravity, it will stop flowing, and the downstream water will dry up because of evaporation. A person can lift heavy things easily; If you love to jump, it's amazing. You flew off the earth in one jump. Many teenagers have worked hard to realize their dream of going into space, and it suddenly became a reality. If we lose gravity, the environment around us will only get worse. People and all kinds of objects are swimming in the air, which is really terrible. To sum up, we can't lose gravity. The existence of gravity is the basis of our human existence on the ball. Article 6

If gravity suddenly disappears

We sit in the classroom and have a physics class. Everyone's textbooks and stationery are neatly placed on the table. We sat in comfortable chairs and listened to the physics teacher. Suddenly, my pencil box floated up and floated around in mid-air. The students stared at it in surprise, and even the teacher stopped lecturing. He is talking about the application of gravity.

When everyone was looking at the pencil case, I found that many tables and chairs began to shake and the lecture table was "trembling". There was a gentle shaking sound. Soon, everyone's books and stationery all floated up, and all the tables and chairs were empty. Then, students and teachers are not allowed to float. Usually, everyone doesn't feel crowded when sitting in the classroom, but now it's a mess, and the ceiling fan lights are floating. Every second, you can hear someone groaning after being hit.

"Everybody be quiet, be quiet", the physics teacher cleared his throat. According to what I said just now, this is the scene after gravity disappeared ... Before he finished, the class was in chaos because everyone found that the wall was shaking. With a loud noise, our main teaching building rushed up in horror ... Chapter VII.

If gravity disappears, what will the world look like? Let's imagine.

Children must be the happiest. Because they don't need to go to parks and playgrounds, they can play some games that we can't even imagine now. They can fly into the sky without any tools and instruments, or they can put kites into space without any wind. Oh, that's incredible!

Of course, in other ways, it also has many functions. For example, if there is no gravity, everyone is a Hercules and can move all heavy objects from east to west and from south to north. In this way, we can easily transport heavy goods and save manpower and material resources. But there are also many shortcomings. If we lose weight for a long time, it will affect the blood transmission of lower limbs. If we don't take appropriate measures, it will lead to the lack of nutrition and even atrophy of lower limb muscles. So we must wear spacesuits to ensure our health. I really don't know what we will become then.

Of course, we should study hard and overcome all difficulties, so that we human beings can survive well in weightlessness. Article 8

If gravity suddenly disappears

Gravity comes from the earth, and it is the attraction of the earth to objects that produces gravity. What would happen to the world if gravity suddenly disappeared?

One day in physical education class, a PE teacher took his students to jump high, and a classmate began to jump up one meter away from the single frame. At this time, gravity suddenly disappeared, and the students jumped up and didn't land. At this time, an uncle is drinking tea at home. Tea has entered his mouth, but it has not flowed into his stomach. Hanging all the time, not being absorbed by the human body.

In the evening, it rained strangely. It was raining, but it never fell to the ground. That's weird. Later, I learned that because the earth lost its attraction to objects, the rain did not fall to the ground. Without gravity, the spring dynamometer hangs an object, and there will be no indication on the spring dynamometer, and the pointer still points to the zero scale. Because gravity disappears, the object cannot bear the vertical downward gravity, so the object will not pull down the spring dynamometer, and the pointer of the spring dynamometer has no indication.

If there were no gravity, all objects in the air would not fall to the ground, so it would be another scene, and I dare not imagine anything.
