The vector field given by is
In vector calculus and physics, a vector field is an assignment of a vector to each point in its domain, a subset of space, most commonly Euclidean space . A vector field in the plane can be visualised as a collection of arrows with a given magnitude and direction, each attached to a point in the plane. Vector fields are often used to model, for example, the speed and direction of a moving fluid thr… WebWhat work really depends on is the field. If you have a conservative field, then you're right, any movement results in 0 net work done if you return to the original spot. With most vector valued functions however, fields are non-conservative. In a non-conservative field, you will always have done work if you move from a rest point.
