آزمایش اتومبیل با هوا
Gelsonlab HSTM-049 DIY Science اسباب بازی با موتور هوا
The آزمایش اتومبیل با هوا pushes the piston backward by compressed air, and the piston rod drives the rack and gear to rotate, so that the car can move forward rapidly. The principle and application of increasing air density to convert gas pressure energy into kinetic energy are studied through experiments.
