Concept in Definition ABC

Distance is a magnitude that measures the relationship of distance or closeness between two bodies, objects or individuals.

For the geometry Euclidean, the distance between two points is the length of the shortest path between them. That is, the measurement the degree of closeness that exists between the two.

Distance measurement, for example, is useful for decide issues as diverse as time and velocity that will require the same to be covered on foot or in a vehicle, the type of communication that can be established between both points, or the difference of scenarios that both points support each other.

For geometry and mathematics distance is a more or less concept abstract that is present in various arithmetic operations. For example, the distance operation from a point to a set, or between two sets.

For the geographyOn the other hand, the measurement of distance responds to the purpose of distinguishing terrain and climatic and natural conditions. In turn, distance also has to do with sociological and cultural differences. A small distance between two geographical points can observe, however, a great separation in moral, social, cultural and religious matters.

That is also the apparent distance or social distance. Beyond its exact calculation, there is the concept of distance as proper to the perception subjective.
For example, two lovers may be at a great physical distance and still feel close to each other.
At the same time, it is often said that although in large cities there is a physical closeness between citizens, the distance emotional it is present in everyday relationships.
Another relevant aspect of distance is the perception that a subject may have at a given moment regarding physical proximity or distance. Depending on the mood of an individual, for example, he may feel that he travels a long distance in a short time, that is, that it is shortened. Or, the other way around.
