Scientific Insights:

In ancient times, people invented two-wheeled vehicles pulled by horses (or cows, donkeys), which can be confirmed by the discovery of Terracotta Warriors and many ancient mural paintings. A "xuan" was a type of vehicle with a high front canopy and tent, used by officials above the rank of ministers. The "d" vehicle was an ancient military cart with four wheels, covered with live cowhide on top and capable of carrying ten people below. It was used for transporting soil and fortifications, primarily for attacking cities. The "d" cart was a type of sedan from ancient times; it is said that Emperor Qin Shi Huang was transported back to the palace in a d cart after his death outside. A "sibche" was a large vehicle with a canopy, which could carry goods or serve as a sedan. In summary, the ancients were very intelligent and invented numerous types of vehicles. Moreover, these vehicles often symbolized status and wealth. However, most of these vehicles were pulled by animal power. Today, we create a small vehicle that moves using wind power.

Experimental Objectives:

1. Understand the working principle of the wind turbine
2. The interaction of knowing power is mutual.

Experimental Cognition:
The interaction between two objects is mutual. When one object exerts a force on another, the second object also exerts a force back at the same time and in the same direction. This pair of forces is known as action and reaction forces. The magnitudes of the action and reaction forces are always equal, and their directions are always opposite, acting along the same line. When a person pushes against a wall, this force is the action force, and the wall also exerts a force back—the reaction force—of equal magnitude. This principle applies to rowing, swimming, and spacecraft flight. When you push a table with your hand, your hand hurts; when you kick a ping-pong ball against the floor, you will find that the greater the force you apply, the higher the ball jumps.

Scientific Expansion:

1. It refers to forces of equal magnitude, opposite direction, acting on two objects along the same line, and with the same nature.
2. Balanced forces are two forces acting on the same object, with equal magnitudes, opposite directions, and acting along the same line. The properties of the two forces can be different.
3. Two forces that are in mutual balance can exist independently, and their interaction forces arise and disappear simultaneously.
4. In mutual forces, only two objects are involved (the force-applying object is also the object receiving the force), whereas in balanced forces, three objects are required (two force-applying objects and one object receiving the force).
5. The interaction forces act on two objects respectively, while the balanced forces act on one object together.
6. The interacting forces have no resultant force; there is only a resultant force for the balanced forces.
7. The forces involved in interactions have their own effects, while balanced forces share a common effect. Based on the nature of the forces, they can be classified into elastic forces, friction forces, gravitational forces, etc. The forces and reaction forces between objects always belong to forces of the same nature. For a pair of forces and reaction forces, it cannot be said that one force is the cause and the other is the result. Either of the two forces can be considered a reaction force, and the other becomes a reaction relative to it.

Scientific Exploration:

Do you know? For thousands of years, people have been researching an ideal mode of transportation on roads. Ancient ancestors tamed cows and horses and created various human and animal-powered vehicles, but humans were not satisfied with this. In the 19th century, with the development of the Industrial Revolution, steam cars became popular. Many people used steam cars attached to vehicles, but the real car (using a gasoline engine as power) was born in Germany in 1886. German engineer Carl Benz manufactured a three-wheeled vehicle with a 0.85 horsepower gasoline engine in Mannheim in 1885. On January 29, 1886, a patent application was filed, and this day is recognized as the birth date of the world’s first car.

Please check that the circuit is unobstructed and all components are intact before assembly, as well as ensure all contact points are properly aligned. During assembly, be careful not to let glue get on your clothes or skin. Keep the components out of reach for younger siblings to prevent them from accidentally swallowing them! Do not play with them on your head, as the model may fall and hurt you!
