Poems about physical mechanics
1. Poems about "Principles of Mechanics"
The emperor descended to Beizhu, his eyes were misty and sad, the autumn wind was blowing in the cave, and the leaves were falling in the cave... - "Mrs. Xiang" 》·Qu Yuan used geometric mechanics to observe these two poems, which is also quite interesting. The surging "waves" are upward, the withered "wooden leaves" are downward, and the "autumn wind" is advancing from north to south on the plane of the earth - three When the forces in these two directions combine in a poem, they promote the movement of the seasons and the pulse of our poetic life in another way.
Poetry and Physics Teaching Yuzhong County No. 1 Middle School Ding Cheng China is a kingdom of poetry. Poetry not only brings artistic enjoyment to people, but also contains certain physical knowledge in some works.
Using this precious wealth and inserting poetry into physics teaching will definitely be the icing on the cake. 1. Using poetry to introduce physical concepts can make students more interested and active.
For example, when talking about some concepts of the motion of objects, we can use the verses from Chairman Mao's poem "Sending the God of Plague": "Sit on the ground and travel eighty thousand miles a day, survey the sky and see a thousand rivers in the distance." From this Introducing the concept of motion as an absolute, the earth beneath our feet is constantly in motion.
Chen Yuyi, a poet of the Song Dynasty, wrote in a poem called "Xiangyi Daozhong": "The flying flowers shine in the evening red on both sides of the bank, and the wind blows half a day on the hundred-mile elm embankment. I lie down and look at the clouds in the sky without moving, and I don't know the clouds. Stay with me."
From the last two poems, we can introduce the concept of stillness. Here, the ship and the cloud move at the same speed. Using the ship as a reference, the cloud is stationary.
Another example is Tao Yuanming's "The sun sinks down the West River, and the plain moon rises out of the East Ridge", and Li Bai's "The lonely sail is far away and the blue sky is gone, but only the Yangtze River skyline is seen" can introduce some concepts of movement. These poems are vivid, vivid and interesting.
By introducing physics concepts in this way, students will listen with interest, the classroom atmosphere will be active, and the effect will be twice the result with half the effort. 2. Using poetry to understand physical concepts can make students think fluently and make a deep impression.
When understanding the interaction between special bodies and the decomposition of forces, and analyzing the reasons why kites can float in the air, you can read "The Kite" by Wu Youshui in the Qing Dynasty to students: "Only relying on the power of the wind can make the kite fly." , It’s true that the feathers are abundant. The red line flies through the sky, and the blue clouds have a way to go."
And the force analysis was done, and the effect was excellent. Another example is when teaching the law of straight-line propagation of light and the formation of shadows, using "Flower Shadow" by the Song Dynasty poet Su Shi can help students understand: "There are many layers on the Yaotai, and the children can't sweep them away after repeated calls.
It has just been swept away by the sun, and the bright moon is sent to the future." Another example, when talking about the dispersion of colors, we can use Mao Zedong's poem "Bodhisattva Barbarian Dabai Di": "Red, orange, yellow, green, blue, blue, purple, who holds the color and practices it in the sky." Dance.
The sun sets after the rain, and the mountains are green. 3. Use physics knowledge to appreciate Chinese poetry and make it useful for students.
After learning about the reflection of light, The word "frost on the ground" in Li Bai's poem "The moonlight shines in front of the window, it is suspected to be frost on the ground" will give you a deeper understanding. Another example is Li Bai's "Looking at the Lushan Waterfall": "The sun shines on the incense burner, and the purple smoke rises, and the waterfall hangs in front of the river." .
The flying stream falls three thousand feet, and it is suspected that the Milky Way has fallen into the sky. "The majestic waterfall turned into the Milky Way falling into the sky in the poet's eyes.
Without knowledge of optics, I am afraid that the understanding of these two poems will not be too deep. Another example is through studying physics, the students Knowing some concepts of time and space, let us review Li Bai's "Early Departure from Baidi City": "The White Emperor's farewell speech among the colorful clouds, thousands of miles of rivers and mountains are returned in one day.
The apes on both sides of the bank can't stop crying, and the boat has passed the Ten Thousand Mountains. " This poem talks about the movement of people and boats in space.
From the Baidi in the west to Jiangling in the east, it flows down the river for thousands of miles. Amidst the bursts of ape calls, as the boat moves Everywhere the location changes, you can see mountains and valleys in various shapes, which makes people feel relaxed and fascinated.
I leave Baidi in the morning and arrive in Jiangling in the evening. This kind of spatial movement is not accompanied by "one day". 4. Use physical knowledge to identify Chinese poetry, so that Hesitation can view the problem dialectically. After studying the chapter of "Physical Changes", insert Zhang Ji's popular "Mooring on the Maple Bridge": "Moonset". The sky is covered with black tellurium frost, and the river maple and fishing fire are facing melancholy.
At Hanshan Temple outside Gusu City, the midnight bell rang for the passenger ship. "Through careful analysis, we can see that there are indeed mistakes in this poem.
According to physical knowledge, when the dew point drops below zero, the water vapor on the earth's surface condenses and forms frost. It can be seen that frost It is formed on the ground, and it has never been in the sky. How can it be said that "the sky is full of frost"? Apparently the poet Zhang Ji believed that frost, like snow, fell from the sky, which violated the laws of nature.
Of course, literature is not physics after all. It allows the use of imagination and synaesthesia. Moreover, we cannot ask the ancients to use today's scientific knowledge to write poetry.
However, physics. If teachers can guide students at any time to use the physics knowledge they have learned to appreciate and identify the works of their predecessors, it will be of great benefit to stimulate students' curiosity, cultivate a wide range of students' interests, strengthen physics concepts, and improve teaching effectiveness. Reading this article, I don’t know if it will be useful to you.
2. Verses about "Principles of Mechanics"
The emperor's son descended to Beizhu, his eyes were dim and melancholy, the autumn wind was blowing in the cave, and the leaves were falling... ——"Mrs. Xiang"·Qu Yuan came to the world with geometry It is quite interesting to observe these two poems. The surging "waves" are upward, the withered "wooden leaves" are downward, and the "autumn wind" is advancing from north to south on the plane of the earth - the forces in three directions combine into one In the poem, it promotes the movement of the seasons and the pulse of our poetic life in another way.

I lie down and look at the clouds in the sky without moving, and I don't know the clouds. Stay with me."
From the last two poems, we can introduce the concept of stillness as a relative concept. Here, the ship and the cloud move at the same speed. Using the ship as a reference, the cloud is stationary.
Another example is Tao Yuanming's "The sun sinks down the West River, and the plain moon rises out of the East Ridge", and Li Bai's "The lonely sail is far away and the blue sky is gone, but only the Yangtze River skyline is seen" can introduce some concepts of movement.

After learning about the reflection of light, The word "frost on the ground" in Li Bai's poem "The moonlight shines in front of the window, it is suspected to be frost on the ground" will give you a more profound understanding. Another example is Li Bai's "Wanglu Mountain Waterfall": "The sun shines on the incense burner and produces purple smoke, and the waterfall hangs in front of the river." .
The flying stream falls three thousand feet, and it is suspected that the Milky Way has fallen into the sky. "The majestic waterfall turned into the Milky Way falling into the sky in the poet's eyes.

1. The mountains are reflected in the floating water, and there is no water and no mountains without me.
——Modern·Wu Mai's "Guilin Landscape"
Physical principles: reflection and refraction of light.
Translation: Mountains stand in the water, and there are reflections of the mountains in the water. There is no mountain that is not attractive, and there is no water that is not attractive.
2. Hanshan Temple outside Gusu City, the midnight bell rang for the passenger ship. ——Tang Zhang Ji's "Night Parking on the Maple River"
Physical principle: the propagation of sound.
Translation: In the lonely and quiet Hanshan Ancient Temple outside Gusu City, the sound of ringing bells in the middle of the night reached the passenger ship.
3. The green mountains on both sides of the strait face each other, and the lone sail is coming from the sun. ——"Looking at Tianmen Mountain" by Li Bai of the Tang Dynasty
Physical principle: Green hills are stationary relative to the ground, but with a moving boat as a reference, the green hills become moving. With the river bank as a reference, Gufan comes from the sun.
Translation: The beautiful scenery of the confrontation between the green mountains on both sides of the Taiwan Strait is indistinguishable. I met a lonely boat coming from the horizon.
4. The beauty of April in the world is gone, and the peach blossoms in the mountain temple are beginning to bloom. ——"Peach Blossoms at Dalin Temple" by Bai Juyi of the Tang Dynasty
Physical principle: The higher the terrain, the slower the temperature rises. In the same season, the temperature on the mountain is lower than that at the bottom.
Translation: In April in the human world, all the flowers have withered, but the peach blossoms in the ancient temples on the mountains have just begun to bloom.
5. The water of the Yellow River comes up from the sky and rushes to the sea never to return. ——Li Bai of the Tang Dynasty, "The Wine Will Be Entered"
Physical principle: water cycle.
Translation: The water of the Yellow River rushes from the sky, and the waves roll straight to the East China Sea, never to return. 4. Ancient poems containing physical phenomena
What I searched online:
1. A thousand miles to Jiangling in one day: moving at a high speed
2. The light boat has passed Ten Thousand Mountains: This poem uses mountains as a reference, and the boat moves relative to the mountains
3. The boundless falling trees rustle: the leaves fall to the ground under the action of gravity
4. The endless roll of the Yangtze River: the river water flows to low-lying places under the action of gravity
5. Thousands of sails passing by the side of the sunken boat: a description of relative motion. Since your own boat is not moving, the boat next to it is not moving. The ship is in motion relative to itself
6. How much sorrow can you have, just like a river of spring water flowing eastward: In our country, the east is lower than the west, and the river flows downward under the action of gravity. flow. . (Physics + Geography)
7. The bright moon rises over the sea, the end of the world ***At this time: Because the moon is far away from the earth, the range of moonlight is large. . (Physics + Geography)
8. The sound of wind, rain and reading is heard in the ears: explanation: 1. The propagation of sounds will not interfere with each other; 2. Sound can propagate around obstacles.
9. Snow in the mountains in May, no wind but cold: This shows that places with high latitudes receive less heat from the sun and the cold weather lasts longer. (Physics + Geography)
10. The grass is dry and the eagle's eyesight is weak, and the snow is gone and the horse's hooves are light: The grass is yellow, and the animals have no protective camouflage, allowing the eagle in the sky to see more clearly. This is light. Phenomenon; because there is no snow on the ground, the horse runs faster. This is a mechanical phenomenon.
11. The Yuyang Pier stirred the earth to come, shocking the song of colorful feathers: The previous sentence shows that the ability of the earth (solid) to transmit sound is stronger than that of air.
12. You know it is not snow because of the subtle fragrance: it looks like snow (white), but through the identification of taste, you know the essence of the substance, and the subtle fragrance is caused by the movement of molecules. of. (Physics + Chemistry)
13. The spring river tide is connected to the sea level, and the bright moon on the sea is rising with the tide: The previous sentence means that due to the effect of the earth’s gravity, the water level of the rivers connecting the sea everywhere is at the same level as the sea level. same height.
14. If you don’t see it, the water of the Yellow River will come up from the sky and rush to the sea never to return: the physical phenomenon is the same as the 6th line of the poem.
15. Hanshan Temple outside Suzhou City, the midnight bell rings to the passenger ship: judge the object making the sound based on the timbre of the sound.
16. Can draw the eagle bow like the full moon, look northwest, and shoot at the wolf: a fully drawn bow contains elastic potential energy.
17. Flying down three thousand feet: Water falling from a height includes the conversion of gravitational potential energy and kinetic energy.
18. The high autumn wind roars in August and rolls up the triple thatch on my house: the moving air (wind) has kinetic energy.
19. When Chaimen hears a dog barking, he returns home on a snowy night: Sound can convey information. Through the barking of a dog, he knows that someone is coming back.
20. If you want to see a thousand miles away, go to a higher level: only by climbing high can you see far away. (Physics + Geography)
Haha, I thought about it for more than an hour before I recalled these, so I didn’t classify the same phenomenon. I hope the poster can be satisfied. If the poster reads ancient poems, he will definitely be able to Find out more answers. 5. Find poems that contain physical knowledge, and indicate what kind of physical knowledge they contain
1. At Hanshan Temple outside Suzhou City, the bell rings at midnight to the passenger ship
2. "The morning of the morning" Saying goodbye to the colorful clouds, thousands of miles of rivers and mountains are returned in one day. The apes on both sides of the bank can't stop crying, and the boat has passed the Ten Thousand Mountains.
" (Tang Dynasty·Li Bai·"Early Departure from Baidi City")
Analysis: The first two lines of the poem literally mean that the poet wants to travel "a thousand miles" to and from Jiangling in "one day", which is 12 hours It takes 2000 miles (1000 kilometers = 1000 kilometers) to travel. Based on this, the ship speed is roughly calculated: v=s/t=1000 kilometers/12 hours ≈ 83.33 kilometers/hour. The speed of the boat is only 10~21.6 kilometers/hour. The boat Li Bai took is too fast. In fact, this expresses the poet's mood of returning home.
3. "Moving the boat to dock." In Yanzhu, at dusk, guests are worried about the new things. The trees are low in the open sky, and the clear moon on the river is close to the people. " (Tang Dynasty·Meng Haoran·"Staying at Jiande River")
Analysis: The poet stayed at the inn at dusk and still watched the night scene with great interest. The water of Jiande River was so clear and calm that the poet used the water as a mirror. The bright moon seems to be close by, and I can sit back and relax tonight. It is obviously the "plane mirror" that makes the bright moon in the sky "image" in the water. 4. Wen Tianxiang, the national hero of the Southern Song Dynasty, once vowed in "The Yangtze River" to "Be a minister." A piece of magnetic needle stone will never stop until it points to the north." Here the author uses the magnetic needle stone as a metaphor for his determination to resist gold.
Analysis: One of the properties of magnets is to guide the north, so Wen Tianxiang uses "the magnetic needle stone to guide the north." The nature of this metaphor is a metaphor for the firm determination to resist gold. This reminds people of Wen Tianxiang's famous saying, "No one has died in life since ancient times, and his loyalty will reflect history." Today's people are inspired to resonate with the emotions of the ancients, which arouses deep feelings in their hearts. Patriotism.
5. When the flowers bloom, you know it is suddenly warm, and the magpies sing through the trees to welcome the new weather.” These are two poems from the Southern Song Dynasty poet Lu You's "Village Book Joy". The first sentence can be understood from a physical point of view as: the aromatic oil molecules secreted by the flowers accelerated, indicating that the surrounding temperature suddenly dropped at that time.
Analysis: The poet expressed his admiration for the beautiful nature in a beautiful style, and accurately described the details of the changing seasons. "The fragrance of flowers is astonishing" means that the poet has felt the fragrance of flowers before he has been in contact with them. This is caused by the irregular movement (diffusion) of aromatic oil molecules secreted by flowers. Only when the surrounding temperature suddenly rises will he feel the "sudden fragrance". warm".
6. "Small bamboo rafts in the middle reaches of the river, walking on both sides of the towering green mountains", these two lyrics have been deeply rooted in the hearts of the people with the famous movie "Shining Red Star". Please use your physics knowledge to analyze the phenomenon.
p>
Analysis: "Walking" and "swimming" represent two different actions. In physics, they are called mechanical motion. "Swimming" in the Zhupai River is based on the ground or the green hills on the ground. "Walking" on both sides of the "green mountain" is actually a kind of personification. If a person stands on a "bamboo raft", if the bamboo raft is used as a reference, then the green mountain will be moving.
7. Washing the water! With the moon in your hand, your clothes will be filled with the fragrance of flowers
Physics knowledge:
"Holding the water with the moon in your hand" is the phenomenon of mirror reflection
"The clothes will be filled with the fragrance of flowers. "It is: the phenomenon of molecular diffusion.
8. Purple smoke is emitted from the incense burner under the sun, and the waterfall hanging in front of the river is seen in the distance. The water flows down three thousand feet, which is suspected to be the Milky Way falling from the sky.
Physics knowledge: The kinetic energy of the "flying down" water is increasing, and the gravitational potential energy of the water is decreasing
9. The peaks reflect the floating water, and there is no mountain and no water without being mesmerized
Physics knowledge: Reflection and refraction of light
10. The peach blossoms on the human face reflect the red color
Physics knowledge: The red light reflected by the peach blossoms is the determining factor of the color of the object
11. Smell it Know the person by the sound
Physical knowledge: timbre, one of the three characteristics of music
12. Li Yi, a poet of the Tang Dynasty, has a poem called "Happy to see my younger brother and say goodbye again" ", which describes: "After ten years of separation and chaos, we met each other when we were older. We were surprised when we first met when we asked each other for our last names, and recalled our old appearance by calling them names. Thinking of the "old appearance" of the first sight in "Asking for a Surname", it can be seen that there is a feature in the voice that reminds the poet of memories from ten years ago. This feature is timbre, one of the three major characteristics of music
I wonder if that’s enough? 6. Poems, proverbs, or idioms related to physics knowledge
1. A small weight weighs a thousand pounds - According to the principle of lever balance, if the power arm is a fraction of the resistance arm, then the power is several times the resistance. If the force arm of the weight is very large, then it is entirely possible to "lift a thousand pounds with one or two strokes".
2. A broken mirror cannot be reunited - when the distance between molecules is large (greater than a few hundred angstroms) , the gravitational force between molecules is very small, almost zero, so it is difficult to reunite a broken mirror.
3. What cannot be picked is the moon in the mirror. What cannot be picked is the flower in the water - the image formed by a flat mirror is a virtual image.
4. When people unite, Mount Tai will move - If the directions of each component force are the same, then the resultant force is equal to the sum of the magnitudes of each component force.
5. Lifting tofu with hemp rope - it cannot be lifted - when the pressure is constant, if the force-bearing area is small, the pressure will be large. Supplementary answer 6. Real gold is not afraid of fire, and truth is not afraid of debate. From the perspective of the melting point of gold, although it is not the highest, it is still 1068°C, and the temperature of the general flame is about 800°C. Since the temperature of the flame is lower than that of gold, melting point, so gold cannot melt.
7. The moon is haloed by wind, and moist by rain. When strong winds come, the temperature in the sky drops rapidly, and water vapor condenses into small water droplets. These small water droplets are equivalent to many prisms, and the moonlight passes through these "prisms" "Dispersion occurs and a colorful moon halo is formed, so there is a saying that "the moon halo causes wind".
Base moisture refers to the reverse moisture on the ground. Before a heavy rain comes, the air humidity is high and the ground temperature is low. The water vapor near the ground condenses into small water droplets when condensed. In addition, the salt contained in the ground easily absorbs moist moisture. water vapor, so the reverse tide on the ground indicates that heavy rain is coming.
8. When a person roars loudly in the mountains, the valley echoes. The sound can form a loud echo through multiple reflections. It lasts for a long time, as if the mountains are roaring and the valleys are roaring. In echo.
