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. So from this equation we obtained four important principles. Number one, the greater the mass of that particle is, the greater the sedimentation coefficient is and the greater the sedimentation speed is. So if we are examining two particles, let's say the blue particle a and the green particle B.
