Centrifugation can be given by  mw2/r......it shows that m mass and r radius are directly proportional to the Centrifugation …..this shows that as size increases....the rate of Centrifugation also increases...and thus molecule with higher mass or density would sediment faster...hope u understand😊

I'm extremely sorry...r is inversely proportional...w is directly proportional to centrifugation(w(angular momentum)....it was my mistake...sry...

Centrifugal force is a force arising due to inertia of a body which appears to act on a body moving in a circular path and is directed away fro the center. Centrifugal force occurs as an opposite force to balance centripetal force(directed towards center).
Since Inertia is directly proportional to mass the heavier particle tend to sediment,this is the principle of centrifugation. Common examples of centrifgation: Formation of butter from curd, blood plasma from blood during blood test

							The formula is F=mrw² where w is angulae velocity represented by omega....and not mw²/r😒..............................
