Basic Concepts Of Vectors

Geometrically we can represent a vector as a directed line segment whose length is the magnitude of the vector and with an arrow indicating the direction. Vectors are generally oriented on a coordinate system the most popular of which is the two dimensional cartesian plane. Good examples of quantities that can be represented by vectors are force and velocity.

Basic concepts of vectors vectors.

Basic concepts of vectors. Lets start this section off with a quick discussion on what vectors are used for. Vectors are used to represent quantities that have both a magnitude and a direction. If l is a straight line in a plane or three dimensional space then we can provide two directions to. A quantity that has magnitude as well as direction is called a vector.

We can define a vector as an object that has both a direction and a magnitude. As we have studied in school physics there are some physical quantities which require both magnitude and. The cartesian plane has a horizontal axis which is labeled x and a vertical axis labeled y. Basic concepts of vectors directed lines.

Some advanced applications of vectors in physics require using a three dimensional space in which the axes are x y and z. Two reference lines drawn at right angles to each other as shown in fig. For problems 1 4 give the vector for the set of points. Find its magnitude and determine if the vector is a unit vector.

From the figure above the. Both of these have a direction and a magnitude.
