In Cartesian coordinates : In words, the vorticity tells how the velocity vector changes when one moves by an infinitesimal distance in a direction perpendicular to it.
WebU vektorskom kalkulusu, divergencija je operator koji mjeri intenzitet izvora ili ponora vektorskog polja u datoj tački; divergencija vektorskog polja je skalar. Za vektorsko polje koje pokazuje brzinu širenja zraka kada se on zagrijava, divergencija polja brzine imala bi pozitivnu vrijednost, jer se zrak širi. Da se zrak hladi i skuplja, divergencija bi bila … WebStokes' theorem, also known as the Kelvin–Stokes theorem after Lord Kelvin and George Stokes, the fundamental theorem for curls or simply the curl theorem, is a theorem in vector calculus on .Given a vector field, the theorem relates the integral of the curl of the vector field over some surface, to the line integral of the vector field around the boundary of the …
In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space.
