A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

Newton's Second Law: The acceleration of an object is proportional to the resultant external force acting on it, inversely proportional to its mass, and the direction of acceleration is the same as the direction of the resultant external force. Heavier weights are subjected to greater gravity, and the force required to pull the car is also greater. The mass of the small car is the same. According to Newton's second law, a larger pulling force will give a larger acceleration, so the acceleration of the small car with a heavy mass weight is greater than that of the other small car.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
