What is a position vector BA?
The position vector is a straight line having one end fixed to a body and the other end attached to a moving point and is used to describe the position of the point relative to the body. As the point moves, the position vector will change in length or in direction or in both length and direction.

- Vectors that specify the position of the body are known as position vectors. Often they start at the origin and terminate at an arbitrary point.
- Displacement is the vector difference between the ending and starting positions of an object.
- A displacement vector tells you how much the object’s position has changed. The displacement vector includes how far you have travelled and in whic...
- The position vector of points A and B is AB = (x 2 – x 1 , y 2 – y 1 ) = (x 2 – x 1 ) i + (y 2 – y 1 ) j
- A position vector is defined as a vector that indicates either the position or the location of any given point with respect to any arbitrary refere...

Using the information above, we can generalize a formula that will determine a position vector between two points if we knew the position of the points in the xy-plane. For example, consider a point P, which has the coordinates (xk, yk) in the xy-plane, and another point Q, which has the coordinates (xk+1, yk+1). The formula to determine the positi...
In this section, we will discuss some position vector example problems and their step-by-step solutions. This will help to build a deeper understanding of position vectors. Example 1 Given two points A = (-4, 6) and B = (5, 12), determine the position vector AB. Then, compute the magnitude of the vector AB. Solution Given two points in the xy-coord...

Sep 12, 2022 · The position vectors are drawn from the center of Earth, which we take to be the origin of the coordinate system, with the y-axis as north and the x-axis as east. The vector between them is the displacement of the satellite. We take the radius of Earth as 6370 km, so the length of each position vector is 6770 km.
In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector that represents a point P in space. Its length represents the distance in relation to an arbitrary reference origin O, and its direction represents the angular orientation with respect to given reference axes. Usually denoted x, r ...
