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. If these particles have the same shape, have the same size, have the same density, but they have different masses, the mass that is greater will basically move with a higher sedimentation coefficient. So we'll have a higher sedimentation speed. So if the mass of the blue particle is greater than the mass of the green particle, but the size and shape is the same, then the higher mass travels down a test tube more rapidly.
