WebThe curl of a gradient is zero Let f ( x, y, z) be a scalar-valued function. Then its gradient ∇ f ( x, y, z) = ( ∂ f ∂ x ( x, y, z), ∂ f ∂ y ( x, y, z), ∂ f ∂ z ( x, y, z)) is a vector field, which we denote by F = ∇ f . We can easily calculate that the curl of F is zero. We use the formula for curl F in terms of its components In vector calculus, a conservative vector field is a vector field that is the gradient of some function. A conservative vector field has the property that its line integral is path independent; the choice of any path between two points does not change the value of the line integral. Path independence of the line integral is … See more In a two- and three-dimensional space, there is an ambiguity in taking an integral between two points as there are infinitely many paths between the two points—apart from the straight line formed between the two points, one … See more Path independence A line integral of a vector field $${\displaystyle \mathbf {v} }$$ is said to be path-independent if it depends on only two integral path endpoints regardless of which path between them is chosen: for any pair of … See more If the vector field associated to a force $${\displaystyle \mathbf {F} }$$ is conservative, then the force is said to be a conservative force.

$The idea of the curl of a vector field - Math Insight$

WebIf curl of a vector field F is zero, then there exist some potential such that $$F = \nabla \phi.$$ I am not sure how to prove this result. I tried using Helmholtz decomposition: $$F = \nabla \phi + \nabla \times u,$$ so I need to show that $\nabla \times u=0$ somehow. multivariable-calculus Share Cite Follow edited Aug 4, 2016 at 16:14 Chill2Macht

To see why this works, you need to take the curl of the above equation; however, you'll need some delta function identities, especially. ∇2(1 / r − r ′ ) = − 4πδ(r − r ′). If you're at ease with those, you should be able to finish the proof on your own.

WebA third type of curl free vector field is described in frame dragging, and is best represented as one or more moving wave fronts of vacuum stress energy. WebThink of a curl-ful field as a whirlpool--you could imagine going around and around and building up speed in it. But a curl-free field might be more like a river. You can flow down the river, but if you go back and forth down the river you spend as much time going up as you do going down, so you can't get anything out of it.
