I think what you ment was a mass to frontal area to velocitity conversion yes ?
Not really I do not metion velocity at all. Mass to frontal area however is more or less SD.
Try it like this:
a pound of lead will fall at a given rate . if it is 12x12 inches it will fall slower than if it is 2x2 inches .
the same is true given a copper ball of a given wieght and an identical lead ball that is heavierthe lead ball falls faster.
This is correct except in a total vaccum. I think the fariswmresponse to your post above was misinterpeted. In your example above (I assume the object is 3D ie 12x12x12) you havetwo weights that are identical but the smaller 2x2object is muchdenser. This will infact fall faster because it will have an equal gravitational pull but has far less wind resistance due to the greatly reduces frontal area.
In the copper ball/lead ball example the frontal area and drag are equal, but the gravitation pull is greater on the lead ball so i agree the lead ball will fall faster.
