What factors are involved in sinking and floating? What is the principle of sinking and floating

It is related to two factors, one is self-factor and the other is external.

1.Internal factors are related to the material and shape of the ball, such as the buoyancy of solid and hollow iron balls of the same weight.

2.The external factors are mainly the density of the liquid or gas, and the buoyancy of the same iron ball in water and oil is different.

Sinking and floating conditions: buoyancy greater than or equal to gravity, the object floats or levitates.

Buoyancy is less than gravity, and the object sinks.

Buoyancy. Liquids and gases have an upward pull on the object immersed in them, and this support force is called buoyancy in physics.

An object floating on the surface of a fluid or submerged in a fluid is subjected to the upward resultant force of hydrostatic pressure in all directions. Its magnitude is equal to the gravitational force of the fluid being dislodged by the object. For example, if the gravity of a stone is greater than its weight in the same volume of water, it will sink to the bottom.

The gravity of the timber or hull is equal to the weight of the water discharged by the part of the water in which it is submerged, so it floats on the surface of the water. The weight of the balloon is less than the gravity of its same volume of air, that is, the buoyancy is greater than the gravity, so it will rise. This force of immersion in water or air and the force of water or air pushing the object upwards is called "buoyancy".

For example, a bucket of water from a well is lighter before it leaves the surface than after it leaves the surface, because the bucket is buoyant by the water. Not only water, but all liquids such as alcohol, kerosene, or mercury are buoyant to the objects immersed in it.

It is related to the density of the object.

The sinking of an object in water is related to the float and the density of an object is related to the density of water.

2.When the density of the object is greater than that of water, the object will sink, for example, a solid iron ball will sink if it falls into the water.

3.When the density of the object is less than the density of water, the object can float on the water, for example, we use steel to make a ship, although it is made of steel, but because the inside is hollow, the density of the whole ship is less than that of water, then it floats on the water.

4.When the density of an object is equal to the density of water, the object is suspended in the water, i.e. it can stay anywhere underwater.

5.In fact, submarines are the best example, and they can change their density through their own water intake and discharge, so that they can float and sink or stop somewhere in the water.

6.The water in this question can be replaced with any other liquid.

The buoyant force experienced by the object is greater than less than the gravitational force of the object.

The buoyant force experienced by the object is equal to the mass of the dislodged liquid.

The buoyant force experienced by the object is greater than less than the gravitational force of the object.

The buoyant force experienced by the object is equal to the mass of the dislodged liquid.

The stone was put into the water and sank; The wooden block was put into the water and floated. What is the phenomenon of the rise and fall of objects related to? Iron sinks in the water, but why can a large passenger ship made of steel float on the water and carry a lot of cargo?

What is the reason for the fact that when water is lifted from a well, the same bucket filled with water is much heavier when it leaves the surface than it feels in the water?

In today's science class, Mr. Wang asked us to fill a plastic basin with water, saying that he was going to do a small experiment for us to "sink and float". "Hehe, that sounds interesting! ”

Here we go, here we go! At this time, Zhou Linglong was so happy that she almost didn't jump up. Suddenly, hearing a "boom", the students crowded to the podium like wasps, their eyes fixed on Mr. Wang's hand.

Teacher Wang picked up a small eraser and asked, "If I put this eraser in the water, will it sink?" "Yes!

Everyone said in unison. "Wow, the little eraser is sinking! "Teacher, try my little scissors!

No, try my clear glue first. "Teacher, try my pen. "Let's go with my pencil first!"

Everyone is gossiping, and no one knows which one to try first. The teacher simply asked a few students on the side to get started on their own, "Wow, my scissors are sinking!" "Hey, the pen is sinking too!

After this experiment, I also discovered a little secret: if you put the ruler gently on the surface of the basin, "it will float", and if you throw it into the water from a slightly higher place, "it will sink!" ”。

I also found that the surface of the water seems to have a very thin film, for example, we can gently hold a coin on the surface of the water without sinking, but if we use too much force, it will break the film on the surface of the water and sink.

Science classes are so much fun and science is really amazing!

5. Whether the object sinks or floats in the water.

Look at the mass of the water drained by the object and the mass of the object If the mass of the drained water is greater than the mass of the object, then the blame will be blamed.

Sinking and floating are related to the following factors:

1. The ups and downs of an object are related to its own mass and volume;

2. Objects composed of different materials, if the volume is the same, the heavy object is easy to sink, and if the mass is the same, the object with small volume is easy to sink;

3. The submarine applies the principle of sinking and floating objects in water.

The application of the principle of sinking and shouting floating: submarines.

The phenomenon of sinking and floating has a wide range of applications in life and industry. For example, we can use the buoyancy of an object in a liquid to measure the density of an object; When swimming, we can control the rise and fall of the body by adjusting the posture of the body, so as to achieve the purpose of swimming; In industrial production, we can use the buoyancy of objects in liquids for separation, extraction, and other operations.

In conclusion, the phenomenon of sinking and floating is an important physical phenomenon, which not only has a wide range of applications, but also can help us better understand the properties of liquids and the density of matter.

In conclusion, the phenomenon of sinking and floating is an important physical phenomenon that not only has a wide range of applications, but also helps us better understand the properties of liquids and the density of substances.
