Why does the ship float on the water, and the ship is heavy, why can it float on the water?

The displacement of the boat is greater than the weight of the boat itself, and the boat can float on the water.

To illustrate this problem, we can do an experiment: put a thin sheet of iron in the water, and it immediately sinks; If you make this iron sheet into a box, the weight does not change, but it can float on water; Not only that, but if you put something in the box, the box will only sink a little and still float on the water. This is because the bottom surface of the box is subject to the pressure of water, and this pressure is the vertical upward buoyancy, as long as the buoyancy is greater than the weight of the iron sheet, it will hold the iron box so that it will not sink.

Of course, the pressure of water is also affected around the iron box, but the pressure on the front and back sides of the box is equal in magnitude and opposite directions, canceling each other out; The pressures on the left and right sides also cancel each other out. The buoyancy increases with the depth of the water and increases with the volume of the part of the object submerged in the water. Because the volume of the iron box is much larger than that of the iron sheet, the weight of the water discharged is also much larger, and the buoyancy obtained is also larger, so the contents of the box can still float on the water.

The same is true for large ships that can float on water. The law of the rise and fall of objects was discovered by the Greek scholar Archimedes more than 2,000 years ago, who accurately said: "The amount of buoyancy acting on an object in water is equal to the weight of the water discharged by the object".

The buoyancy is greater than the gravitational force, so it floats in the water.

As long as the buoyancy is greater than the gravitational force of the boat, it can float on the water.

A ship is able to float on the water because it experiences a buoyant force greater than its own gravitational force.

According to Archimedes' principle, the buoyancy experienced by an object in a liquid is equal to the gravitational force of the liquid it dispels. Therefore, when the ship is in water, the gravity of the water it displaces is equal to its own gravity.

Due to the large size of the ship, so is the volume of the water it discharges. This means that the buoyancy on the ship is also large enough to support its weight.

Therefore, despite the ship's weight, it can float on the water.

Because the center of the ship is empty, the ship will be slightly lighter, and the buoyancy that allows the boat to float on the water is affected by the buoyancy.

Because of the buoyancy, the ship can float on the water, and although the ship looks large, the center weight of the ship is relatively small.

Because the buoyancy of water is very large, the structure of the ship is different, so the buoyancy of the water can be used to a greater extent.

The displacement of the boat is greater than the weight of the boat itself, and the boat can float on the water.

i.e. the reason: the buoyancy of an object is related to the volume in which it is immersed in water.

The principle that the ship can float on the water: the steamer made of steel, because the hull is made hollow, so that the weight of its water discharge increases, and the buoyancy of the ship increases, and the buoyancy of the ship is equal to its own gravity, so it can float on the water. It works by taking advantage of the condition that the object floats on the liquid surface, as long as the gravitational force of the boat does not change, whether the boat is in the sea or in the river, the buoyancy it is subjected to does not change.

CausesThe upper and lower surfaces of the object are under different pressures due to the different depths of the liquid (or gas), and the upward pressure on the lower surface is greater than the downward pressure on the upper surface, and the difference between these two pressures forms buoyancy. The magnitude of buoyancy is closely related to the amount of liquid (or gas) that the object is discarding.

Taking an object immersed in a liquid as an example, because the liquid will produce pressure, and the pressure increases with the increase of depth, and there is pressure inside the liquid in all directions, the upward pressure of the liquid on the lower bottom surface of the object is greater, and the downward pressure of the liquid on the upper and bottom surfaces is smaller, and the pressure difference between the upper and lower bottom surfaces of the object is manifested as a vertical upward buoyancy. The pressures on the sides cancel each other out.

Why do ships float on the water.

The boat can float on the water without sinking because it is buoyant by the water, but this does not mean that it cannot sink. The displacement of the ship.

If the weight of the boat is greater than its own weight, the boat can float on the water. If gravity and buoyancy do not act equally, the ship begins to sink.

The principle that the ship will not sink is that the ship has a lot of buoyancy, the ship is mostly a hollow structure, and the material used by the ship is mostly a buoyant raw material, the hollow structure allows the ship to have more buoyancy space, so that the ship can float on the horizontal plane well and not sink, the ship has been in the history of development from the earliest wood that can only use buoyancy materials to now use steel to build the hull, and the ship's anti-sinking performance is getting stronger and stronger.

Because the buoyancy of the ship is equivalent to the gravity of the liquid, the tires will float on the water, and they are also very safe, and they can carry many people, and they are also very safe.

Because the inside of the ship is empty, there will be a lot of buoyancy, and the ship can float on the water.

Although the weight is relatively heavy, it is able to float on the water because of a lot of buoyancy and some professional technology.

The Archimedes' principle was used in the construction of the ship, and then there was a lot of water and buoyancy in the hull, and then there was generally a vacuum in the ship.

This question is like why an airplane can fly into the sky because it is so heavy, and those who don't understand it will never understand.

The ship is made of steel plates, which can displace more volume of water, and the buoyancy of the ship when it is in the water is equal to the gravity of the water, and the buoyancy of the ship can be equal to or greater than the gravity of the steel plate used to make the ship, so it can float on the water.

Steamship: It is made of steel that is denser than water to make a hollow core, so that it can float on the water, and the size of the ship is usually expressed in terms of displacement. The displacement of a ship refers to the gravitational force of the water that is discharged after the ship is fully loaded, that is, the buoyancy of the water when the ship is fully loaded.

According to Archimedes' principle, the buoyancy of an object on the water surface is related to the density of the water, the volume of the water discharged by the ship and the acceleration of local gravity, so although the boat made of iron is very heavy, the volume of the water it displaces on the water surface is also very huge, so the buoyancy generated by these very considerable water is equal to the gravity of the ship itself, and according to the law of conservation of force, you can know that the boat can float on the water.
