# gst: a striking analogy between solid–solid and solid–drop frictions

AA << report that the lateral adhesion force between a liquid drop and a solid can also be divided into a static and a kinetic regime. This striking analogy with solid–solid friction is a generic phenomenon that holds for liquids of different polarities and surface tensions on smooth, rough and structured surfaces >>

AA << acknowledges that their experiments are just the beginning in trying to fully understand the nature of friction between drops and solid objects >>
