Wooden constructor "Inertial car", educational model

Educational STEM constructor - a wooden inertial machine that can be assembled. The constructor helps children get acquainted with the basics of physics and engineering in the simplest way.
Features:
It's a constructor, toy, and educational tool all in one. A fun and educational choice for kids who love to build, experiment, and discover how the laws of physics work.
It is designed to develop children's construction skills, fine motor skills, hand-eye coordination, logical thinking, and understanding of mechanics.
Perfect for curious minds - it combines creativity with science, encouraging problem-solving and imaginative play.
Made of high-quality, non-toxic wood. The wooden parts are smooth and durable, and can be assembled without glue.
The car can be decorated or painted in your child's favorite colors.
Easy assembly: simple and clear instructions allow children to assemble the toy with minimal adult supervision, making the set suitable for both independent work and activities with parents.
STEM (Science + Technology + Engineering + Mathematics) are educational methods that integrate science, technology, engineering, and mathematics into a coherent learning model to prepare the younger generation for a world of rapidly evolving technologies.
This is a great choice for a gift, as well as for schools and educational institutions where simple, reliable and clearly functioning educational models are needed.
Operating principle:
After assembling the model, you need to pull the string back and release it: the spring mechanism inside will make the car move forward.
Engineering and Mechanics: The child learns how individual parts (frame, axles, wheels) fit together to form a working system. Using screws and joints, the child understands structural stability (why it is important to tighten parts tightly).
Potential energy: When the car is pulled backwards, the spring inside compresses and stores energy.
Kinetic energy: When the car is released, the stored energy is converted into kinetic energy.
Friction: It is possible to observe how the grip of the wheels on the surface affects the distance and speed of travel.
Educational value: The child is introduced to the basics of mechanics.
Purpose: for home learning, classroom learning, project activities.
