Jiangling, thousands of miles away, the relationship between distance and time.
Apes on both sides of the strait can't stop crying, and their voices are generated and spread.
The canoe has passed Chung Shan Man, and the change of object position is called mechanical movement.
First, the energy knowledge in ancient poetry
1. Su Shi's poem "Can wave a bow like looking at the moon, looking at the northwest and shooting at wolves". The energy conversion involved in the poem is the conversion of elastic potential energy into kinetic energy.
2. Li Bai's poem "Flying down three thousands of feet, it is suspected that the Milky Way has set for nine days". The waterfall in the poem contains great mechanical energy.
Second, the reference knowledge in ancient poetry.
1, Mao Zedong's poem "Sit on the ground and travel 80,000 miles a day, and see John Wan in the sky" means that "Sit on the ground" is static relative to the ground, and "Walk on the sky" is moving relative to the sun.
2. Li Bai's poem "Looking at Tianmen Mountain" wrote that "the green hills on both sides of the strait look at each other, and the lonely sails come from the sun". "Castle Peak Opposite" takes the ship as the background, and "Solitary sail comes from the sun" takes the river bank as the background.
3. In the lyrics of "Sparkling Red Star", "Small bamboo rafts swim in the middle reaches of the river and walk on both sides of the towering green hills". "Bamboo raft swimming in the middle reaches" takes the earth as the background, and "walking on both sides of Qingshan" takes ships as the background.
4. "A strong wind blew the well out of the fence last night." The well was blown out of the fence with the fence as a reference.
Third, the knowledge of thermodynamics and molecular dynamics in ancient poetry
1. In Lu You's Mountain Village of Happiness, "the fragrance of flowers makes people feel warm, and the sound of magpies makes them shine through the trees". In the poem, "the fragrance of flowers makes people feel happy" is the result of the accelerated random movement of aromatic oil molecules secreted by flowers, and the temperature affects the intensity of molecular movement.
2. In Zhang Xu's Stay in the Mountains, "clothes are mysteriously stuck in the depths of areola even if there is no rain"-the formation (liquefaction) of dew.
3. Bai Juyi's Ode to Mujiang: "On the third night of September, the dew is like a pearl and the moon is like a bow"-the formation of dew (liquefaction).
