Define a location of a non-point object

  1. Dec 29, 2014 #1
    Lets suppose we have a object which its a not a point.Lets call it a segment which is 1 meter.If we want to locate this object in space we need to use coordinates but coordinate is a point.So I think point cannot describe a segment than how I can show it.
    Thanks

    You need more numbers to describe the position of an extended object. (5, not 3)

    You need at least 2 points to think of a segment.

    It depends on your purpose of assigning coordinates.

    For some applications, perhaps calculating orbits, the coordinate of the center of gravity is most important. In others applications, such as collision avoidance, the coordinates of extremities is most important.

    Think of an airplane flying in the sky versus an airplane navigating on the ground at a crowded airport.
