Vector fields and line integrals in the plane

Description
The vector field is defined and explained in this video tutorial. Examples of vector field e.g the picture of wind patterns off the coast California with Santa Ana winds in which all of these vectors shows the velocity of air at every point, is analysed. How the magnitude of a vector field increases with the distance from the origin, this is explained through diagram.
