Falling weights and the force of their blow
Could a lighter weight dropped from higher make the same dent?
The leaf carries a single block of text (one line struck through) posing a problem about the impact of falling weights. A one-pound weight falling one braccio delivers a blow of a certain quality; Leonardo asks whether a half-pound weight would make the same mark if dropped from twice the height, or from double the first height, or as twice the weight from half the height, or as four times the weight from a quarter of the height. Faint offset text shows through from the other side of the leaf.

Weight, height of fall, and equal impact
A weight of one pound falling one braccio gives a blow of a certain quality. Leonardo asks whether a half-pound weight would produce the same dent when let fall from twice the height, or twice the first height, or as twice the weight from half the height, or four times the weight from a quarter of the height.
