The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.
The stadion, also known as the stade, was the standard short distance sprint in ancient Greece and ran the length of a stadium. However, stadiums could vary in size and there was apparently no definite standard length for them, e.g., the stadium at Delphi measures 177 m and the one at Pergamon 210 m.
A metric or distance function is a function d which takes pairs of points or objects to real numbers and satisfies the following rules: The distance between an object and itself is always zero. The distance between distinct objects is always positive. Distance is symmetric: the distance from x to y is always the same as the distance from y to x.
The shortest distance across the strait, at approximately 20 miles (32 kilometres), is from the South Foreland, northeast of Dover in the English county of Kent, to Cap Gris Nez, a cape near to Calais in the French département of Pas-de-Calais. Between these points lies the most popular route for cross-channel swimmers. [1]
This event was called "Short distance" from 1988 to 2000. Since 2002 it is called "Middle distance". Men's short/middle distance. Year Gold Silver Bronze
Top short-distance runners exert as much as four times their body weight in pressure on the running surface. For this reason, muscle mass in the legs , relative to total body weight, is a key factor in maximizing footspeed.
ADSL is generally only installed for short distances from the telephone exchange (the last mile), typically less than 4 kilometres (2.5 mi), [2] but has been known to exceed 8 kilometres (5 mi) if the originally laid wire gauge allows for further [clarification needed] distribution.
The European Union defines any passenger flight between city pairs separated by a great circle distance between 1,500 and 3,500 km (800 and 1,900 nmi) to be medium-haul, below as short-haul, and above as long-haul routes.
