Racing Dynamics R50 Sport
In sport, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves :wikt:traverse, traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, Race stage, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a Individual time trial, time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot racing, chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Old Norse, Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western po ...

Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distance
Distance is a numerical or occasionally qualitative 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"). Since spatial cognition is a rich source of conceptual metaphors in human thought, the term is also frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between strings of text) or a degree of separation (as exemplified by distance between people in a social network). Most such notions of distance, both physical and metaphorical, are formalized in mathematics using the notion of a metric space. In the social sciences, distance can refer to a qualitative measurement of separation, such as social distance or psychological distance. Distances in physics and geometry The distance between physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointe Du Raz
The Pointe du Raz is a promontory that extends into the Atlantic from western Brittany, in France. The local Breton name is ''Beg ar Raz''. It is the western point of the ''commune'' of Plogoff, Finistère. It is named after the ''Raz de Sein'', the dangerous stretch of water between it and the island of Sein (''Enez Sun'' in Breton). It is a dramatic place of crashing waves and strong winds. The word ''raz'' was borrowed from Norman by the Bretons and shares the same etymology as the English word race, "strong current of water"; both are from Old Norse ''rás''. It also marks the western end of the 3,200 km E5 European long distance path to Venice in Italy. The " La Vieille" lighthouse can be clearly seen from the headland. Although it is not quite the westernmost extent of France—that would be Pointe de Corsen, just to the north—its rocky isolation makes it a popular tourist destination, comparable in some ways to Land's End Land's End ( kw, Penn an Wlas or ...
