There is an old saying in our region: “As high as the mountains are, so are the waters!” » I thought this sentence was accurate at the time, because in the mountainous area near us, people living halfway up the mountain didn't bother to drink water. As I grew up, I discovered that this phrase applied to our territory, but this is not the case in some regions. Driven by curiosity, I figured out why this is happening? What should you do if you encounter such a problem?
In our same region, as long as the vegetation on the mountain is lush, there is generally no shortage of water in such a place. For example, there is a temple built on a local mountain with an elevation. about 800 meters. There are practitioners living on the mountain, drinking water comes from a spring dug at the top of the mountain. I have already drunk spring water there, sweet and delicious. However, a girl of oursThe village later got married and moved to a mountainous area tens of kilometers from our village. The reactions came back to his parents, which upset his parents. The village had difficulty drinking water and she had to go there for more than ten hours. kilometers to fetch water in another village. Later, I chatted with her and learned that the vegetation in the local mountains was sparse, the altitude was relatively high, above a thousand meters, and water resources were scarce. The villagers together dug a well more than 30 meters deep. but there was no water?
Later, with the help of the local government, a water well more than 100 meters deep was dug, which solved the local problem of difficulty in drawing water.
This shows that the water is as high as the mountain. Where is he? Water resources are abundant. In low altitude areas there is alush vegetation on the mountains, and if the altitude is high and water resources are not abundant, you will definitely face the problem of difficulty in drinking water. .
I recently watched a video about a village deep in the mountains that had no water to eat. Later, under the leadership of the former village party secretary, the villagers used the mind of the foolish old man. Move mountains from nearby mountainous areas with abundant water resources to high mountains. After more than ten years of hard work, a "heavenly canal" was dug, which solved the water and irrigation problems of local villagers, which is truly admirable.
This shows the importance of choosing a place to live. But people don't choose where they are born! If you were born in a mountainous area where water is difficult to obtain, you must either arrange water resources locallyau for consumption and irrigation, either collect rainwater for reuse, or choose only to move.
In daily communication, we often hear the saying “People go to higher places and water flows to lower places”. In fact, water flowing downward is a very common phenomenon in nature. Today, the editor will use relevant knowledge of physical mechanics to bring you the corresponding explanation.
1. The phenomenon of water flowing to lower places
In our lives, “when people go to higher places, water flows to lower places” is an almost ubiquitous phenomenon . Whether rivers, lakes or seas, they all follow this corresponding law. So, have we ever thought about why water flows to lower places rather than higher places?
2. Knowledgethese relevant in physics
The force exerted by an object due to the attraction of the earth is called gravity. The force exerted by gravity is the center of the Earth. The direction of gravity is always straight. The gravity exerted on an object is directly proportional to the mass of the object. All objects on earth are under the influence of gravity.
3. The physical principle behind the flow of water to a lower place
The flow of water to a lower place is a physical phenomenon. According to universal gravitation, there is a mutual gravitational force between existence and any object with mass in this universe. In the same way, existence and every object on earth is subject to the gravitational pull of the earth. When water is unimpeded by other external forces, it experiences only the gravitational pull of the Earth, and the size of the gravitational pull is closely related to thealtitude of the object. The gravitational force of two objects of the same mass is inversely proportional to the square of their height.
Here I want to explain a fundamental problem. The so-called "lower place" refers to the altitude of two relatively close objects relative to different reference systems, that is, the height of two relatively close objects. nearby objects. For two objects of the same mass, the one whose relative height is greater experiences a weaker gravitational force. When water is subjected to unequal forces, it will naturally flow in the direction that exerts the greatest force on it, that is, it will flow "lower." On a slope, the gravity on the object is vertically downward. Why isn't it moving vertically downward? Because the slope has a supporting force on it, and that force comes from gravity? But the direction of the force of gravity ande the resulting supporting force is downward along the slope. The object will therefore move down the slope. Earth gravity Earth gravity!!
Here I want to explain a fundamental problem, the so-called "lower" refers to the altitude of two relatively close objects compared to different reference systems , that is to say the height. say, for two objects of the same mass, the object with higher relative height will experience a smaller gravitational force. When water is subjected to unequal forces, it will naturally flow in the direction that exerts the greatest force on it, that is, it will flow "lower." On a slope, the gravity on the object is vertically downward. Why isn't it moving vertically downward? Because the slope has a supporting force on it, and that force comes from gravity? But the direction of the force of gravity and the resulting support force is vers down along the slope. The object will therefore move down the slope. Earth Gravity Earth Gravity!!
Newton's Law Earth Gravity Caused by Earth Gravity Water sinks to the bottom from an energy perspective. This is usually the source of water found in high mountains. is due to the formation of surface water from water vapor by precipitation. This way there is some potential energy from the start. Water must have speed when it flows, so it must convert potential energy into kinetic energy. There is no other form of energy conversion if we want to reduce potential energy. the height needs to be reduced, so this explains why the water flows downward!
The attraction of the earth makes it descend. The effect of gravity, like other liquids, has a certain volume but not a precise shape, so it has a fluidity. Water flow is linked to Earth's gravity. BelowThe action of Earth's gravity causes water to flow from higher places to lower places.
4. Application of water in daily life where water flows downward
If humans master this characteristic of water, they can use it to transform nature and fight . wars. Better than nature. For example, many places have dammed rivers and stored water in artificial lakes. This lake is a storehouse of water. When there is a lot of water, it can be stored in the tank. Agricultural land can be irrigated if conditions permit, it can also use the water to generate electricity to prevent water from running off. in vain. In places where there is a lot of water, if the land is low, flooding can easily occur during heavy rains. People took advantage of the feature of water flowing to areas morelowlands to dig rivers and canals to carry away flood waters and ensure a bountiful harvest of crops. Pull: Earth's gravity makes water flow to lower places without hesitation, so water is a weak thing because you can't grab it, but if it builds up for a long time, weak things will explode . Like terrible floods. Gravity Gravity Gravity The earth moves Water must flow down Why does water flow up?
