[math-fun] And I suppose heavy objects fall faster than light ones?
Why do the contents separate? As Newton explained in his second law of motion, the more massive the object, the greater the tug. In the lurching car, an adult feels the force more than a child. In the centrifuge, heavy objects feel it more than light ones and, if possible, they move more vigorously toward the outer wall.
I thought the article did an above-average job of explaining centrifuges, in spite of this gaffe. Rich -------------- Quoting Mike Speciner <ms@alum.mit.edu>:
