Both timelines start together. Length measures elapsed time, not a physical distance.
A little perspective
The time of 30 seconds and the rotation period of Ten-metre centrifuge at two rpm are approximately the same.
Measurements, assumptions & sources +
Ten-metre centrifuge at two rpm
A defined 10 m radius centrifuge rotating at 2 rpm. It produces about 0.439 m/s² centripetal acceleration, expressed here as 0.439 N on a 1 kg sample; speed and period are derived from the same model.
Defined examples — our methodology
The marked rotation period is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares time with rotation period. The records below preserve each value’s basis and caveats.

- Comparing
- Time ↔ Rotation period
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Ten-metre centrifuge at two rpm is labelled derived; treat the displayed value as a comparison anchor rather than false precision.
