What is a position vector?
- Position vectors describe the position of a point in relation to the origin
- They are different to direction vectors which describe the direction and distance between any two points
Distance between two points
- The distance between two points is the magnitude of the vector between them (see Magnitude Direction)
- For position vectors we can find the distance between two points by using the respective co-ordinates
Remember if asked for a position vector, you must find the vector all the way from the origin. Diagrams can help, if there isn’t one, draw one.
