The difference between natural phenomena and physical phenomena related to physics

The magpie nest is high, and the rain is waterlogged that year.

After a long rain and birdsong, it soon turned clear.

Puffins fly upward, and the wind does not wait for darkness.

The bird falls to the boat, and the rainy day is going to pass.

The magpie branches crow, and the sunny day is reported when you go out.

Crickets barked on the house, and crops were blistered.

Mosquitoes bite strangely, and the weather is going to go bad.

Dragonflies are swirling, and the rain is coming.

Bees are busy picking flowers, and there is rain in the short term.

Back sores are itchy and raining in the middle of the night.

Jujube flowers are mainly dry, and pear flowers are mainly waterlogged.

There are no mountains on sunny days, and it rains for three or five days.

The river is mossy, and there will be heavy rain.

The sea foamed yellow, and the wind did not pass long.

The chickens are on the shelves late, and the coming day will change.

Long insects (snakes) stand in the way, and the rain hits the seedlings.

The ants are connected in rows, and the sunny day will not be long.

Dragonflies flew into patches, and the river rose ashore.

Bees are busy collecting honey, and they have to panic when borrowing an umbrella.

Sheep love slope grazing, tomorrow the wind and rain will come early.

The sow cushions the nest, not the cold wind sets the snow.

Clothes are cooled and dried (water evaporates), there is a lot of ice in the refrigerator (water vapor condenses into ice), it will rain (water vapor condenses into water droplets at high altitude), lightning is seen before thunder is heard (the speed of light is much faster than the speed of sound), copper wire is used as a wire (low resistance, low cost), wrench (lever), barrier-free passage for the disabled (slope), crane (pulley), static electricity (positron or negative electrons, etc.), microphone (sound drives magnets to change the current frequency), Speakers (a certain frequency of current is converted into sound by the magnetic effect of the current), mobile phones (radio waves)...

The physical phenomena are:

1. Optical phenomena: such as light bulbs, reflective glass windows, mirrors, luminous cups, luminous shoes, fireflies, etc.

2. Electrical phenomena: such as air conditioners, televisions, hair dryers, lightning rods, etc.

3. Mechanical phenomena: such as thermal expansion and contraction, tricycle pulling, water pumping at the bottom of the well, etc.

4. Thermal phenomena: such as greenhouse vegetables, solar cookers, drying clothes, melting of ice, vaporization of water, etc.

5. Magnetic phenomena: such as TV antennas, radios, satellite receivers, etc.

6. Acoustic phenomena: such as piano playing, flute playing, birdsong and dog barking, horn broadcasting, etc.

Physical phenomena refer to the change of the form, size, structure, and properties (such as height, velocity, temperature, and electromagnetic properties) of matter without the formation of new matter. In other words, physical phenomena refer to physical events or physical processes that can be directly perceived, and are different from physical essences, which are abstractions of the common essential properties of similar physical phenomena.

List:

1. Thin pieces of paper falling from a high place, even if there is no wind, the route of the paper falling is tortuous and changeable.

This is due to the different convex and concave parts of the paper piece, the shape is different, so in the process of falling, the air flow velocity of various places on its surface is different, according to the principle of fluid mechanics, the flow rate is large, the pressure is small, resulting in the uneven air force everywhere on the paper, and changes with the change of the movement of the paper, so the paper continues to roll, zigzag and fall.

2. Frozen meat thaws faster in water than in air at the same temperature. Something that burns hot cools down faster in water than in air at the same temperature.

A cup filled with piping hot boiling water cools down faster when immersed in water than in air at the same temperature. The reason is that the specific heat capacity of water is larger than that of air, and the heat that can be transferred to the meat by the water drop is much higher than that of the air when the water is in contact with the same contact area.

3. Sprinkle some salt on the snowy road surface quickly, these phenomena all show that salt is used as a snow melting agent.

4. When thunder, you see lightning first, and then hear thunder, these phenomena show that light spreads faster than sound!

Therefore, it cannot conduct the charge generated by friction, and if the charge accumulates, it is easy to produce discharge, which will cause gasoline combustion and dangerous accidents.

Wind and rain, thunder and lightning, blizzards, solar eclipses, lunar eclipses, freezing, there are many phenomena in nature.

Natural phenomena refer to certain conditions in nature that are spontaneously formed due to the laws of nature, and are completely unaffected by human subjective factors. For example, the moon is cloudy and sunny, the four seasons change, the climate is warm and cold, windy and rainy, day and night, etc. There are mainly several categories, such as physical phenomena, geographical phenomena, and chemical phenomena.

Everything that is not man-made on the earth is a phenomenon that occurs in nature, such as wind and rain, high tides and low tides, spring, summer, autumn and winter, fog and clouds, solar and lunar eclipses, tsunamis, and so on.

Natural phenomena in life:

1. The quartz clock hanging on the wall, when the battery is exhausted and stops moving, the second hand of Lingtong often stops at the position of "9" on the dial. This is due to the fact that the second hand is most hindered by the gravitational moment at the "9" position.

2. Sometimes when the water pipe discharges water from the adjacent faucet, there is an occasional burst of noise.

All physical, chemical, and biological phenomena that occur in the universe, the starry sky, the atmosphere, the ocean, the sun, the moon, the stars, animals, plants, the earth's environment, etc.

For example, after the beginning of spring, the earth gradually wakes up from its slumber. The snow melts, the plants sprout, and all kinds of flowers bloom one after another.

Two months later, the swallow returned, and soon the cuckoo came. So it turns into the hot summer, which is the time when the plants bear fruit. In autumn, the fruit ripens and the leaves of the plant turn yellow and fall in the autumn wind.

The northern geese fly south, and the insects that are active in the grass in the fields have also disappeared. Everywhere there is a scene of withered grass and sky, ready to meet the cold winter of wind and snow.

1. The nature is different.

Natural phenomena: Natural phenomena refer to certain conditions in nature that are spontaneously formed due to the laws of nature, which are completely unaffected by human subjective factors.

Physical phenomena: Physical phenomena refer to the change of the form, size, structure, and properties (such as height, velocity, temperature, and electromagnetic properties) of matter without the formation of new substances.

2. Different classifications.

Natural phenomena: such as the moon is cloudy and sunny, the four seasons change, the climate is warm and cold, windy and rainy, day and night, etc. There are three main categories: physical phenomena, chemical phenomena, and life phenomena.

Relative to a social phenomenon caused by humans. Lightning, clouds, water, earth, flames, iron ore, and more are natural phenomena.

Physical phenomena: changes in position, volume, shape, temperature, pressure, and the mutual conversion between gaseous, liquid, and solid states. There are also the interaction between matter and electromagnetic fields, the interaction between light and matter, and the interaction and transformation between microscopic particles (electrons, atomic nuclei, elementary particles, etc.), all of which are physical changes.

3.The internal laws are different.

Natural phenomena are the manifestations of objects. Natural phenomena are the relationship between the various components of nature, and man is only one of the components, and the development and change are objective, such as the limbs of life, objective phenomena.

Physical phenomena are the essential forms of objects. Physical phenomena are a branch of natural phenomena, and natural phenomena include physical phenomena.

For example, the natural phenomenon of wind blowing trees and moving trees, the angle of physics can be analyzed, and the air pressure in different places is different, resulting in air flow. When the air currents push the tree, and the torsional force generated by the tree is greater than the thrust of the air current, the branches return to their original positions, so the tree swings.

The first floor answered very well. One more important thing: nuclear phenomena are also physical phenomena. These include decay of matter, fission, and nuclear fusion (also known as thermonuclear reactions). In addition, the evolution of the universe is also included in the scope of astrophysics.

Natural phenomena – all-encompassing, including physical, chemical, biological, and more.

Physical phenomena - physical phenomena refer to the change of the form, size, structure, and properties (such as height, velocity, temperature, and electromagnetic properties) of matter without the formation of new matter.

Natural phenomena include physical phenomena, in other words, physical phenomena are a branch of natural phenomena.
