Scanning spin rate separately makes the centrifuge square law visible. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

One per second gives two acceleration units
Hold radius at 2 m. Spin rate 1 per second gives acceleration 2 metres per second squared.
a=u2r=1Hz2⋅2m=2m/s2
Doubling rate quadruples the acceleration
Spin rate 2 per second at the same radius gives acceleration 8 metres per second squared. This is the square-law contrast row.
a=u2r=2Hz2⋅2m=8m/s2
Three per second makes eighteen acceleration units
Spin rate 3 per second gives acceleration 18 metres per second squared. The three rows separate rate-squared physics from radius effects shown in the previous chapter.
