Viscosity is, essentially, fluid friction. like friction between moving solids, viscosity transforms kinetic energy of (macroscopic) motion into heat energy. heat is energy of random motion at the molecular level, so to have any understanding of how this energy transfer takes place, it is essential to have some picture, however crude, of solids and/or liquids sliding past each other as seen on friction, sliding friction and rolling friction can make the calculations of frictions related phenomena more accurate. references [1] y. xu and k. l. yung, вђњthe effect of inertial normal force on the rolling friction of a soft sphere on a hard planeвђќ,

.Friction [PDF Document]. Tact area during sliding, make friction force to depend also on system dynamics. such interaction between friction and the response of the system within which it exists can not be modeled through the traditional use of coeffficient of friction. friction and normal forces develop at the true contact areas between surfaces. between two nominally flat surfaces, true contact takes place among the, friction, sliding friction and rolling friction can make the calculations of frictions related phenomena more accurate. references [1] y. xu and k. l. yung, ␜the effect of inertial normal force on the rolling friction of a soft sphere on a hard plane␝,.
