A brachistochrone curve is just the shape. You only need longer space if you want to making it 100cm in height.

Yeah, or you can make it 100 cm long (I'm not sure as to what the resulting height must be). What I'm saying is that instead of using the 100cm measurement vertically, maybe you can use it horizontally. If you do use a shorter ramp, also use a shorter vehicle.

The statements above maybe invalid depending on the response to this questions: Do the rules restrict the 100cm to the vertical height of the ramp?

In that case, then just use a smaller ramp (scale everything down, including your vehicle)

The rules clearly specify the orientation of the dimensions.

Oh okay, never mind then. (Sorry, I don't have my rules yet)

This brings up an interesting question. Is it better to have a shorter ramp in the shape of a brachistochrone curve, or a taller ramp to maximize on potential entergy? I'm leaning towards maximum potential energy.

As the point of the vehicle is to get to the target point as fast as possible, wouldn't it make the most sense to have the ramp "maximize on potential energy", and leave the accuracy of the vehicle to the engineering of the vehicle itself?

I'm not sure what you mean by accuracy, but the brachistochrone curve is the path in which a object can get from one point to another at the shortest period of time. But I agree, you probably want to start with the maximum potential energy so that you have the maximum velocity when you reach the track.

Is there an effective way you can have a medium of the two, or would not be effective as choosing one of them?

I think there is some confusion here about what Brachistochrone means exactly. It just means the curve that minimizes the EDIT*time* for an object rolling of any shape. You can still have a brachistochrone curve that will maximize potential energy (that is ~1m tall).

Why would you want to minimize speed?
