Bouncing as reflected motion; a wheel divided into sectors
The rebound is always weaker than the fall, with sector calculations
Leonardo observes that a bounce is always smaller than the descent that produced it, naming this rebound 'reflected motion' and calling it always weaker than direct motion. Below the note a circle divided into sectors is drawn amid columns of figures such as 3640, 4290 and 7930. A short marginal phrase reads 'the road of the marquis.'

Reflected motion is weaker than direct motion
The rebound of a falling object is always less than the descent it made, and Leonardo names this rebound 'reflected motion.' He states as a rule that reflected motion is always weaker than direct (straight) motion.
Columns of figures beside a sectored circle
Several columns of numbers (3640, 4290, 7930, and paired values such as 165/260, 990/1040, 330/260) accompany a circle divided into sectors. They record calculations tied to the divided wheel.
A wheel or circle divided into sectors
A circle is drawn and partitioned by radii into several sectors, like a wheel. The division is the geometric figure to which the surrounding calculations refer.
