WebThe rst says that the curl of a gradient eld is 0. If f : R3!R is a scalar eld, then its gradient, rf, is a vector eld, in fact, what we called a gradient eld, so it has a curl. The rst theorem says this curl is 0. In other words, gradient elds are irrotational. Theorem 3. WebTo summerize the 2d-curl nuance video : if you put a paddle wheel in a region that you described earlier, if there is a positive curl, that means the force of the vector along the x axis will push harder on the right than on the left, and same principle on the y axis (the upper part will be pushed more than the lower).
