And if the F value is lowered and everything else is kept the same, then what that means is if our denominator is lower but the numerator is kept constant, then the S value will increase. And so the more spherical our particle is, the higher arrow sedimentation speed is. So more spherical particles have lower frictional coefficient values F than less spherical particles of equal mass. So what equal mass means we're basically keeping all these other constants, all these other quantities constant, but we're changing the F value. So therefore, more spherical particles move more rapidly than less spherical particles do. So in a following diagram, if these two masses, let's say the blue masses mass A and the green mass is mass B, if they have the same exact masses, but this one is more spherical and this one is more elongated, then the spherical one will travel down the test tube with a greater sedimentation rate.
