The mechanics cart (tri-combination) consists of three experiments: the balloon experiment (principle of reaction and impulse), the rubber band experiment (potential energy to kinetic energy conversion), and the weight experiment (friction and gravity testing), making it a well-balanced and effective product. Note: The frame is made of galvanized iron, which is not very hard, allowing for slight adjustments to the vehicle's structure (personal customization).

The principle of counter-impulsive motion:
After releasing the balloon, under the action of pressure, the air escapes from the balloon, exerting a backward force on the surrounding air. According to the principle of action and reaction, the surrounding air exerts a forward force on the balloon, causing the balloon to move in the opposite direction of the blowing hole. In a simple explanation, this is the principle of mutual action and reaction. Initially, the balloon was in a state of equilibrium, with the pressure of the gas inside balanced by the reaction force of the tension of the balloon. When the opening is made, the tension at the point of the gap is considered to disappear in an instant, leading to the gas moving from a high-pressure area to a low-pressure area, spewing out from the exit.

Rubber band experiment:
The conversion of potential energy into kinetic energy, elastic deformation, elastic deformation refers to the change in relative positions of points within a solid caused by external forces. When the external force is removed, the solid returns to its original state, which is called 'elastic deformation'. The parts of an elastic body, due to the interaction of elastic force, also have potential energy, which is called elastic potential energy. The greater the deformation of the same elastic body within a certain range, the more elastic potential energy it has, and vice versa.

Weighing Force Experiment:
The principle of the gravity car movement is to convert the gravity of the falling weight into power to drive the car forward. However, while the car is moving forward, friction and other resistance will prevent the car from moving forward, ultimately causing the car to stop.

 Human beings initially completed all work labor by themselves, with no cars or engines at all. If there were any, it was the human body that was used as the engine before the use of cattle and horses. Slavery was a form of 'biological engine.' As human progress and development deepened our understanding of the natural world and our ability to utilize and transform nature, people not only used human and animal power but also knew how to use water and wind power. Cars, which have their own power to drive and do not need to rely on tracks or electrical infrastructure, are vehicles that can move around. In a broad sense, vehicles with four wheels are generally called cars. Since the end of the last century, cars have experienced more than one hundred years of wind and rain. From the first three-wheeled car built by Karl Benz, which could run at a speed of 18 kilometers per hour, to the present, it has given birth to cars that can accelerate from zero to 100 kilometers per hour.A supercar that only takes about three seconds to reach 60 mph. In the past century, the development of cars has been so astonishing! At the same time, the automobile industry has also created many giants, who have established famous companies such as General Motors, Ford, Toyota, and Honda, which play a pivotal role in the economies of various countries. Let's look back on this history, savor the bitterness and joy, and experience all the joy and dreams that cars have brought us... Cars, like other modern advanced complex tools such as electronic computers, were not invented by one person sitting there. The initial invention of cars was not the current design. If you could see the cars of the time, you might also think that they are not cars. The development of cars also has a long history, and overall, the history of car development may be divided into three stages: before the invention of the steam engine, the advent of steam cars, and the beginning of mass production of cars.

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
