The larger marble always goes further in distance than the smaller marble. As the elevation of the ramp increases so does the average speed of the marble right.

When an object is in free fall gravity increases its velocity by 9 8 m s with every passing second. While marble is slightly harder and denser than limestone both rate very low on the mohs scale a rating used to measure the hardness of stones. Glass cutting boards are very hard almost as hard as steel and will not score which is why these boards are notorious for dulling even the best of knives. Did the marble travel faster as it went farther down the slope.

Because acid etching leaves a whitish mark it is much more noticeable on colored marble than on.
