Definition of a scalar and vector field. how to visualize a two dimensional vector field. join me on coursera: imp.i384100 mathematics for engin. In this video we introduce the notion of a vector field, how it differs from a scalar field, and how to plot a basic 2d field by hand.

A field is a function in three dimensions, with its own blend of derivatives.when you're preparing to study advanced physics concepts, it's important to lear. A vector field is a field of vectors where there is a vector associated with every point in the plane (or space). a vector function gives you an ordered pair, or a point, for every value of t. a vector field gives you a vector (not necessarily in standard position) for every point. Both the vector field and the scalar field can have the same domain, e.g., (r^2) as in your example. but, a scalar field has (r) as codomain whereas a vector field has (r^n) with (n>1) as codomain. the vector field maps points to vectors whereas the scalar field maps points to scalars. – tobias. may 3, 2015 at 16:45. A vector field in which the vector at point \((x,y)\) is tangent to a circle with radius \(r=\sqrt{x^2 y^2}\); in a rotational field, all vectors flow either clockwise or counterclockwise, and the magnitude of a vector depends only on its distance from the origin unit vector field a vector field in which the magnitude of every vector is 1.

Describe the difference between vector and scalar quantities. identify the magnitude and direction of a vector. explain the effect of multiplying a vector quantity by a scalar. describe how one dimensional vector quantities are added or subtracted. explain the geometric construction for the addition or subtraction of vectors in a plane. 4.1.2 vector fields. examples of vector fields include the electric field e ( r ), magnetic field b ( r) and the velocity field v ( r) of a fluid. a two dimensional vector field has x and y components that can vary over space. the magnitude of a vector field will produce a scalar field.
