And this has to do with the shape of that particle. So the more spherical our particle is, the lower the value of F is and the less spherical that particle is, the higher the value of F is. So we see that the higher the F is, the higher the sedimentation coefficient is, the higher the sedimentation speed is. And that means the faster that particle will move along and down that test tube. And by down, we mean towards this end of our test tube and not towards this end. Now let's take a look at the following equation and let's try to see what this equation actually tells us with respect to how these different types of factors actually influence the sedimentation speed and the sedimentation coefficient of our particle.
