I'm really late here, but a few problems: - Time and space resolution might be too low to allow a meaningful estimate of air resistance, especially if the camera angle doesn't allow you to accurately determine the rock's 3D shape. - Encoding the color in RGB eliminates spectra. - If it didn't already have knowledge of the properties of minerals and elements, it would need to calculate them from first principles. Without looking into this specifically, I'd be surprised if it was computationally tractable, especially since the AI doesn't know beforehand our fundamental physics or the values of relevant constants.
