Stair-Climbing Spring
Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Composition: Consists of an ABS plastic molded box, an ABS plastic molded base, an ABS milky white plastic molded operating surface with a color silk-screened flip-up instruction board, a staircase structure, a spring, etc. Operation: Place the spring on the edge of the highest step, bend the upper half of the spring toward the lower step, and observe the motion of the spring. Scientific Principle: Why does the force make the spring go down the stairs? When the spring is released, it begins free fall. As the pulling force at the top suddenly disappears, the elastic force of the spring still exists. The top spring accelerates downward under its own gravity and elastic force. As the top spring descends, the elastic force of the lower spring decreases. When the elastic force is less than the spring's own weight, the spring begins to descend, and the downward acceleration gradually increases.
