What if there were no gravity on Earth?

But ignoring physics, one day imagine that the planet is closed and that the earth suddenly has no gravity. This will be a very bad day. We use gravity to control various things such as cars, people, furniture, pencils and paper. There was no reason to stop at all that suddenly did not stop, it began to emerge. However, it rises not only in furniture etc. The two more important things that gravity acts on the ground are the atmosphere and the sea, the lake and the river. Without gravity, there will be no reason for the atmospheric air to move around, soon will jump into space. This is the problem that the moon faces - it is close to a vacuum because the moon does not have enough gravity to maintain the surrounding atmosphere. Without the atmosphere any creatures will soon die and any liquid will boil into space.

If gravity suddenly doubles, it will almost double because all will double. There is a big problem in any structure. Houses, bridges, skyscrapers, table legs, pillars, etc. all have normal gravity dimensions. When double loading, most structures crash quickly. There may be problems with trees and plants. There is a problem with the power cord. The atmospheric pressure doubles, and it has a big influence on the weather.

This answer tells you the impact of global gravity on our world. We can not live without it, we can not change it. It's one of the true constants in our lives!

Gravity is a trajectory that makes the earth circle around the sun and the moon circling around the earth. Because of its size, the gravity of the sun is much bigger than the gravity of the earth. Also, because the size is small, the gravity of the moon is much smaller. If we are going to walk on the moon, it feels like we are floating in the air, only partially compressed by our own quality. Even if the gravity of the moon is weak, it affects the fluid on the surface of the earth. Waves and tides are affected by the gravity of the moon

Obviously, gravity is very important on the planet. Due to the sun's attraction, our planet orbits around the sun. The movement of the moon is influenced by the attraction of the sun and the earth. The gravity of the moon pulls the earth and the tide changes every day. When the moon crosses the ocean, the sea level will expand. As the Earth rotates, the moon crosses the new part of the Earth and moves the waves. The tide is irrelevant to the phases of the moon. Even in the full moon or the new moon, the movement of the moon is the same. It is still in the same basic position

As the earth rotates, the gravity of the moon will pull the various parts of our planet. Even though the Moon is about one hundredth of the mass of the Earth, it is close to us, so it has sufficient gravity to move the object. Even the gravity of the moon may even be raised to land, but someone is not enough to say it (unless they use special and very accurate tools). However, what you should be aware of is that this is just a tidal explanation, not an actual tide. In the real world, the earth is not a global ocean covered with a uniform layer of water. There are seven continents, and the land is blocking the road. The mainland will prevent water from completely following the movement of the moon. This is the reason that the difference between climax and low tide is not so large in one place, but the difference is very big in other places.

The ocean tide on the earth is due to the gravity of the moon and the gravity of the sun. In general, the ocean tide is not the overall gravitational intensity, but it is caused by the difference in gravity (gravity gradient) from one point to the next. Even if the sun is big, its gravity is stronger than the moon and the moon is close to the earth, so its gravity gradient is stronger than the sun. The ocean tide is the influence of seawater according to the gravity gradient, so the moon plays a big role in the occurrence of the tide over the sun. But the gravity gradient of the sun on the earth is important, it also helps the tide
