of a vector field A, the vector characteristic of a “rotating component” of field A. The curl is represented by the symbol rot A. It can be interpreted in the following manner: Let A be the velocity field of a fluid flow. At a given point of the flow we place a small wheel with...
The divergence of vector point function is scalar quantity and curl of vector point function is vector quantity.Answer and Explanation: Given A vector field {eq}F\left( {x,y,z} \right) = \left( { - 6yz, - 9xz,xy} \right) {/eq}. The vector point function...
Determine curl from the formula for a given vector field. The second operation on a vector field that we examine is the curl, which measures the extent of rotation of the field about a point. Suppose that FF represents the velocity field of a fluid. Then, the curl of FF at point PP ...

The force vector (2) is defined by the field we are in. No derivatives or other changes are necessary -- every point in the field has some force acting on it. So, our formula for circulation is: Remember, velocity is simply the derivative of position (r), so (dr) is a vector givi...
