- Because these two rings in the Citadel are connected, then the further you are out from the center of rotation, the more centripetal force you will feel.
Examples

-
By Newton's laws, a particle of mass m in uniform circular motion experiences a centripetal force equal to mv² / r (v is the uniform speed and r is the radius of the circle).

Morphology
centripetal = center (semi-transparent) = centri + petal
While 'centri-' suggests a relation to 'center', 'petal' is not a standalone English word, making the connection less direct.
Etymology
Centripetal combines centri- 'center' and -petal 'to seek', so it literally means 'moving toward the center'. In physics this helps you imagine a skater pulling her arms in as she spins, with motion directed inward toward the center.
