Distance

  • Distance is a measurement of how far a position or object is from another on a given path
  • Example: The distance from Dallas to Little Rock is 319 miles on Interstate 30
  • The distance between two points x2 and x1 on a number line is equal to the absolute value of the difference between the two points or |x2 – x1| = √(x2 – x1
  • The distance between two points that form a line segment that is NOT parallel to the x or y axis on a coordinate plane can be found with the distance formula
Distance (Wikipedia)

Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). In most cases, "distance from A to B" is interchangeable with "distance from B to A". In mathematics, a distance function or metric is a generalization of the concept of physical distance, a way of describing what it means for elements of some space to be "close to" or "far away from" each other. In psychology or social sciences distance is a non numerical measurement; Psychological distance is defined as "the different ways in which an object might be removed from" the self along dimensions such as "time, space, social distance, and hypotheticality.
