The phenomenon is not fully understood but appears in most cases to be caused by the separation and reunification of static electric charges , see also triboelectric effect .
Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion.It is highly interdisciplinary, drawing on many academic fields, including physics, chemistry, materials science, mathematics, biology and engineering. [1]
Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube.A sphere of known size and density is allowed to descend through the liquid.
