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. With a greater sedimentation speed. Now, number three, a more dense particle moves quicker than a less dense particle. So remember, the density of our particle in this equation is basically given by the V bar.
