5. Metrics Examples in Our Everyday World
These metrics can be used for curved lines as well as straight lines. For example, we can measure two points across the earth, and as we all know, the earth is curved.
Our surface is two-dimensional, and two different points need to be measured as such. This is where metrics come into play. Once these two points have been chosen, this coordinate system will be used to determine the distance between these two points.
There is sometimes a difference between a straight-line path and a curved path, such as distances in space or around the earth. This is due to the distance projections that were made prior to measuring distances using metrics.
