Frame of Reference with 2 Objects
This section provides an example of a frame of reference with 2 objects, where locations of other objects are described based where they are located on the line that connects the 2 reference objects.
If the object we are describing is located outside of the reference object, we need an extra reference object build a larger frame of references.
For example, when a jet plane formation flies across the sky as shown in the following picture and someone says "look at the middle jet plane", he/she is using 2 objects, the bottom jet plane and the top jet plane, together as the frame of reference.
Of course, for a larger formation with more jet planes as shown in the next picture the 2-object frame of reference is not good enough. You will have a hard time to describe the location of any jet plane that is not on the line that connects the 2 reference objects.
