field F(x) = (11) is a constant vector field with all the vector field arrows being parallel Figure 1 illustrates an example of a radial field namely the
What is the equation for a constant vector?
x = c 1 t + c 0 ⇒ d x / d t = c 1 .
In summary, a constant vector field like F = kj is conservative if it has a scalar potential and is curl free.
Is a constant vector a scalar field?
A scalar field is a field that only has a magnitude at each point in space, while a vector field has both magnitude and direction. A constant vector field is equivalent to a scalar field because the magnitude of the vectors in the field is constant, making it behave like a scalar field.
What is a continuous vector field?
We say the vector field F is continuous in some region of the plane if both M(x, y) and N(x, y) are continuous functions in that region.
A vector field is a vector function of position. At each position its value is a vector. We can have a constant vector field, meaning at each position the vector is the same. But in general a vector field can have an arbitrary value for the vector at every position.
