The hundred birds in Chinese mythology and legend. In the ancient totemic era of China, it was regarded as a bird and worshipped. Metaphorically speak, a person with holy virtue. It has a long history and is the auspicious bird imagined by people in primitive society, gradually evolving through the embellishment of its original image. Feng, along with dragon, Lin, and turtle, are collectively known as the "Four Spirits of the Book of Rites". It is also regarded as the bird of the Chinese spirit. Experimental objective: To provide children with more knowledge and hands-on abilities through game entertainment. Principle application: An airplane rises and glides by parallel propulsion, and a good hand thrown flight trajectory should be a beautiful arc. Many people mistakenly throw the airplane at a high angle into the air and glide again, which can easily cause it to stall and not fly far. Experimental cognition: The takeoff of an airplane utilizes the Bernoulli principle. The wing is made into a geometric shape with an upper arc and a lower plane or concave, so that when the wing moves forward, the air flow velocity above is faster than that below. According to Bernoulli's principles of fluid mechanics, the air below will exert pressure on the upper part, which is the lift of the wing, lifting the aircraft and allowing it to fly in the air. The basic principle of throwing an airplane by hand is also inseparable from the airplane, which only relies on throwing it forward by hand to provide thrust Knowledge Expansion: According to the law of conservation of energy, it is known that energy neither disappears nor arises out of nothing. It can only transform from one form to another. In low-speed flowing air, the only energy involved in conversion is pressure energy and kinetic energy. A certain quality of air has a certain pressure, which can push objects to do work; The greater the pressure, the greater the pressure energy; The flowing air has kinetic energy, and the higher the flow velocity, the greater the kinetic energy. Knowledge extension: The velocity of air only comes from the effect of the propeller carried by the engine on the air, and of course, analyzing energy from this is also a matter of balance.
