The principle of flying is buoyancyThe airplane didn't fly based on the principle of buoyancy. The ability of an airplane to fly mainly relied on the following key principles:
1. * * The wings generate lift **: This process involves the Bernoullian principle, that is, the greater the flow rate of the fluid (including airflow and water flow), the lower the pressure; the lower the flow rate, the greater the pressure. The special shape of the aircraft wings created a pressure difference between the upper and lower surfaces of the wings, thereby generating lift. In addition, the lift was also related to the angle of attack.
2. * * Thrust provided by the engine **: The forward movement of the aircraft depends on the forward traction force generated by the rotating propeller driven by the power of the engine or the forward thrust generated by the jet. Different types of engines, such as piston-type engines, turbine jet engines, turbine fan engines, and turbine propellers, worked in different ways, but they all provided power for the aircraft to move forward.
3. * * Control plane adjusting flight attitude **: The aircraft's pitch movement is controlled by the elevator, the roll is controlled by the aileron, and the yawing movement is controlled by the rudder. For example, although the B2 bomber did not have a traditional tail, the gold-bellied wing at the trailing edge of the wing could move up and down to act as an elevator to control the pitch. It could assist in the yawing through differential control, and the spoiler could also help the aircraft yawn.
4. * * Center of Gravity and Balance **: The layout of the various parts of the aircraft must ensure a reasonable center of gravity to maintain balance in flight. For a special type of aircraft such as a helicopter, the rotation of the large propeller would generate lift to balance the gravity, and the tail propeller was used to maintain horizontal stability and prevent the body from rotating due to the conservation of momentum.
The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!

Junior high school physics chapter 10 buoyancy review teaching reflectionThere were many situations in the buoyancy review class. In terms of teaching objectives, students should be taught to master the calculation method of buoyancy, the principle of Archmedes, the conditions for objects to float and float, and the application of buoyancy. However, there were some problems with the teaching process:
1. ** Teaching content **
- [Target direction and difficulty grasp: Although the revision content is clear, there is still room for improvement in the direction of the target and the grasp of the depth of the difficulty.] For example, some revision lessons had some shortcomings even though they had completed the content. The revision content did not completely point to the goal, and the depth of knowledge needed to be improved.
- ** Problem Setting and Connection **: The problem setting should be able to review the knowledge points and compare the questions to reflect the differences, guide the solution method, and realize the knowledge transfer. However, in actual teaching, sometimes there would be a lack of connection between the questions, so that the value of the questions could not be fully displayed, and the opportunity to guide the students to solve the questions was missed.
2. ** Teaching Difficulties **
- ** Outstanding points **: Some of the revision lessons were not very difficult. For example, the concept of buoyancy and the principle of Archmedes were both important and difficult points. However, they were not outstanding enough in the teaching, and the process of obtaining the principle was difficult.
- ** Difficulty of exercises and students 'situation **: Buoyancy knowledge is comprehensive, and the difficulty of exercises is high. Students are easily confused, resulting in more classes for new lessons and exercises. Teachers are also confused about whether they need so many classes.
3. ** Teaching methods **
- ** Students 'subjective initiative **: The teacher's teaching method sometimes restrains the students too much, limits the students' thoughts, and does not give full play to the students 'subjective initiative. It is not prepared enough to deal with the "unexpected" situations that the students guess. For example, the students' guesses about the factors related to buoyancy may have limitations. The teacher should guide them.
- ** Student participation and practice questions **: In the teaching process, there are not enough displays, and the participation of all the students is not enough. The practice questions are not selected properly, and there is no gradual progression. In addition, when there was more teaching content, students would have less time to practice, so they should choose exercises with a low starting point, low difficulty, and one-step calculation to consolidate their knowledge.
4. ** Teaching Success **
- "** Teaching method innovation **: We can stimulate students 'interest through innovative teaching methods. For example, we can perform magic in the introductory segment (such as" Obedient Little Fish "), and then explain the principles with physics knowledge. This can stimulate students' interest and meet the teaching goal of applying what they have learned.
- ** Understand the students 'knowledge mastery **: Arrange activities such as "Buoyancy in Life" and let the students explain the application of buoyancy and think about the principle. This can not only motivate the students to answer questions, but also understand the students' mastery of buoyancy.
- ** Temporary change **: In the classroom teaching, according to the students 'deep understanding of buoyancy knowledge, make temporary adjustments to the teaching content, such as the teaching process of the weighing method. Put the time on the principle explanation, which can achieve better teaching results.
- ** After-class summary **: Set aside enough time (such as 12 minutes) for the after-class summary segment. By typing questions on the projection, such as "What knowledge have you learned (both in and out of class)","What is the use of this knowledge", etc., students can summarize and consolidate their knowledge.
