WebAug 15, 2024 · So gradient fields and only gradient fields (under additional regularities) have curl identically equals to zero. You can also see that there are fields whose flows (and elementary flow density in every point, that is their divergence) always amount to zero.

WebMar 14, 2024 · A property of any curl-free field is that it can be expressed as the gradient of a scalar potential ϕ since ∇ × ∇ϕ = 0 Therefore, the curl-free gravitational field can be related to a scalar potential ϕ as g = − ∇ϕ Thus ϕ is consistent with the above definition of gravitational potential ϕ in that the scalar product WebJun 11, 2012 · The short answer is: the gradient of the vector field ∑ v i ( x, y, z) e i, where e i is an orthonormal basis of R 3, is the matrix ( ∂ i v j) i, j = 1, 2, 3. – Giuseppe Negro Jun 11, 2012 at 8:48 2 The long answer involves tensor analysis and you can read about it on books such as Itskov, Tensor algebra and tensor analysis for engineers. WebSep 7, 2024 · is a scalar potential: grad ( f) = F (proof is a direct calculation). For simplicity, let's say your vector field F: R 3 → R 3 is defined everywhere, is of class C 1, and is divergence free. Then, the vector field A: R 3 → R 3 defined as A ( x) := ∫ 0 1 t ⋅ [ F ( t x) × x] d t , where × is the cross product in R 3 , will satisfy curl ( A) = F. cirith ungol king of the dead t shirt
