In ancient times, people invented the two-wheeled cart pulled by horses (or oxen, donkeys), which can be confirmed by the excavation of the Terracotta Army and many ancient relics and murals. Xuan was a kind of ancient carriage with a higher front and a tent, for the use of officials and above. The chariot was a kind of ancient war chariot, a four-wheeled cart, covered with raw cowhide, and could accommodate ten people. It could also be used to transport soil to fill the moat, with the main task of attacking the city. The chariot was an ancient reclining carriage, it is said that when Qin Shi Huang died outside, it was transported back to the palace by the chariot. The supply car was a kind of ancient large car with a canopy, which could carry goods and also be used as a reclining car. In short, the ancient people were very clever and intelligent, inventing various kinds of cars. These "riding horses" symbolize the identity and status of the noble and wealthy. However, most of these cars were drawn by animals. Today, we sit in a small car that moves by wind power.
1. Principle hint, "interaction force": Interaction force occurs when one object exerts a force on another object, and the affected object will certainly return an equal and opposite force to the object that applied the force. This pair of forces are mutually called action and reaction forces, and a pair of interaction forces must be generated and disappear at the same time.
2. Understanding the 'Wind-powered Cart' Principle: The force between two objects is always mutual, and the action force and the reaction force are always equal in size and opposite in direction, acting along a straight line. When a person pushes against a wall, this force is the action force, and the wall will give you an equal and opposite reaction force. The wind-powered cart uses this principle to make the cart move forward!
