what is the difference between a vector and a line?
610939
Vectors are not lines and they have a very different function than lines. A vector is a direction and a magnitude, that's it. ... A line, of course, has direction and magnitude, but it also has LOCATION. A vector can be anywhere, but a line exists within space.

Lesson Summary A vector is an ordered list of elements and differs from a scalar by having both magnitude and direction. They are normally written either vertically as column vectors or horizontally as row vectors.

A vector space is a set of possible vectors. A vector field is, loosely speaking, a map from some set into a vector space. A vector space is something like actual space - a bunch of points. A vector field is an association of a vector with every point in actual space.

The main difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths.

Technically, a line is a row of contiguous elements. Furthermore, a line does not ordinarily need to be a straight-line. A row is always visualized as rectilinear. A row does not necessarily have to have all its elements touching each other (without a gap).

vector function has both quantities magnitude and direction whereas scalar has only one quantity which is magnitude. ... scalars have magnitude but no direction.

- A vector is a dynamic array, whose size can be increased, where as an array size can not be changed. - Reserve space can be given for vector, where as for arrays can not. - A vector is a class where as an array is not. - Vectors can store any type of objects, where as an array can store only homogeneous values.

Vector and ray are symbolized the same way: a line segment with an arrow on one end but they are very different things. A vector has a direction and a magnitude (for example, 5 km south-east). A ray has just a direction and a starting point, and it has infinite length. ... One end ends in a point, and the other is a line.

Originally Answered: what is the difference between Vector, Factor and DataFrames in R ? Vector is an atomic data strcture. It can hold only one data type (for eg: character/ numeric / logical). ... Factors are used to store and use categorical data in R.

What is the difference between array and vector processing in computer organisation? ... In computer languages, when they exist, vectors are a one-dimensional data structure. Arrays, in turn, can have more than one dimension. They are typically used to store images, matrices, tensors, etc.

A scalar field is something that has a particular value at every point in space. ... A vector field is the same as a scalar field but except for only having a value at every point in space, it has a value and direction at every point in space. My go-to example if a vector field is Earth's gravitational field.

What is raster and vector? ... The key difference between raster and vector charts is in the way in which they are rendered, where rendering is process of translating the chart data into an image which can then be displayed on the screen. The screen is always raster display, that is, it is made up of dots.

Image: The difference of two vectors. The difference of two vector x=b−a is formed by placing the tails of the two vectors together. Then, the vector x goes from the head of a to the tail of b.

A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points. A line is defined by two points and is written as shown below with an arrowhead.

A is a quantity that has both size and direction. Speed is not a vector because speed is a measure of how fast or slow an object moves, not which direction it moves in. Velocity, however, has a size—the speed—and a direction, so it is a vector quantity.

A unit vector is a vector of length 1, sometimes also called a direction vector (Jeffreys and Jeffreys 1988). The unit vector having the same direction as a given (nonzero) vector is defined by. where denotes the norm of , is the unit vector in the same direction as the (finite) vector .
