Long Jumper
The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point. Along with the triple jump, the two events that measure jumping for distance as a group are referred to as the "horizontal jumps". This event has a history in the ancient Olympic Games and has been a modern Olympic event for men since the first Olympics in 1896 and for women since 1948. Rules At the elite level, competitors run down a runway (usually coated with the same rubberized surface as running tracks, crumb rubber or vulcanized rubber, known generally as an all-weather track) and jump as far as they can from a wooden or synthetic board, 20 centimetres or 8 inches wide, that is built flush with the runway, into a pit filled with soft damp sand. If the competitor starts the leap with any part of the foot past the foul line, the jump is declared a foul and no distance is recorded. A layer of plasticine is ...

2007 Military World Games Long Jump
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube (algebra), cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as Symbolism of the Number 7, highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the Brahmi numerals, beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit m ...

Plasticine
Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids. Though originally a brand name for the British version of the product, it is now applied generically in English as a product category to other formulations. Plasticine is used for children's play and as a modelling medium for more formal or permanent structures. Because of its non-drying property, it is a material commonly chosen for stop-motion animation, including several Oscar-winning films by Nick Park. History Franz Kolb, owner of a pharmacy in Munich, Germany, invented an oil-based modelling clay in 1880. At the time, the city was a centre for the arts, and among Kolb's circle of friends were sculptors. They complained about how with the clay they were using for modelling, their sculptures would dry too fast and that — particularly in winter —, it was too difficult to work with. In order to commercialize his invention, he presented it to the Faber-Castel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velocity
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Constant velocity vs acceleration To have a ''constant velocity'', an object must have a constant speed in a constant direction. Constant direction cons ...

A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Througho ...

Athletics At The Olympics
Athletics has been contested at every Summer Olympics since the birth of the modern Olympic movement at the 1896 Summer Olympics. The athletics program traces its earliest roots to events used in the ancient Greek Olympics. The modern program includes track and field events, road running events, and race walking events. Cross country running was also on the program in earlier editions but it was dropped after the 1924 Summer Olympics. Summary Events The events contested have varied widely. From 1900 to 1920, tug of war was considered to be part of the Olympic athletics programme, although the sports of tug of war and athletics are now considered distinct. Men's events No new events have been added to the men's athletics programme since the 1952 addition of the short racewalk. The roster of events has not changed since then, with the exception of the omission of the long racewalk in 1976 (the IAAF held a 50 km walk World Championships that year instead and as a resu ...

Summer Olympic Games
The Summer Olympic Games (french: link=no, Jeux olympiques d'été), also known as the Games of the Olympiad, and often referred to as the Summer Olympics, is a major international multi-sport event normally held once every four years.

Chionis Of Sparta
Chionis of Sparta or Chionis of Laconia (; ; ) was an ancient Greek athlete who won multiple events at the ancient Olympic Games representing the city of Sparta in Laconia.Christesen 2010 p. 67 Eusebius of Caesarea lists Chionis as victor in both the ''stadion'' and ''diaulos'' races at the 29th, 30th and 31st Olympiads (conventionally dated 664–656 BC).Christesen 2010 p. 28 Pausanias' ''Description of Greece'' credits Chionis with a fourth ''stadion'' victory in the 28th games of 668 BC, which Eusebius assigns to Charmis of Sparta. Pausanias says that Chionis was an oikist at Battus of Thera's foundation (631 BC) of Cyrene, Libya. Paul Christesen suggests that claim may, on the one hand, date from much later heroization of Chionis by Sparta's Agiads seeking an alliance with Cyrene, but, on the other hand, may have some basis in fact. Chionis' record number of Olympic victories was not matched until 480 BC, when Astylos of Croton (representing Syracuse in Sicily) won his thi ...

Halteres (ancient Greece)
Halteres (; el, ἁλτῆρες, from "ἅλλομαι" - ''hallomai'', "leap, spring"; cf. "ἅλμα" - ''halma'', "leaping") were a type of dumbbells used in Ancient Greece. In Ancient Greek sports, halteres were used as lifting weights,Norman Gardiner, ''Athletics in the Ancient World'', Dover, 2002, oGoogle books/ref> and also as weights in their version of the long jump, Halteres were held in both hands to allow an athlete to jump a greater distance; they may have been dropped after the first or second jump. The athlete would swing the weights backwards and forwards just before take-off, thrust them forwards during take-off, and swing them backwards just before releasing them and landing. Halteres were made of stone or metal, and weighed between . They added about to a long jump. History Recognized as the Greek equivalent of modern-day dumbbells, the halteres served multiple uses from training to competition. Ancient Greek records shows the evidence of the halteres da ...

A Competitor In The Long Jump, Black-figured Tyrrhenian Amphora Showing Athletes And A Combat Scene, Greek, But Made For The Etruscan Market, 540 BC, Found Near Rome, Winning At The Ancient Games, British Museum (7675649600)
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Halteres From Ancient Greece
''Halteres'' (; singular ''halter'' or ''haltere'') (from grc, ἁλτῆρες, weights held in the hands to give an impetus in leaping) are a pair of small club-shaped organs on the body of two Order (biology), orders of flying insects that provide information about body rotations during flight. Insects of the large order Diptera (flies) have halteres which evolved from a pair of ancestral hindwings, while males of the much smaller order Strepsiptera (stylops)Merriam-Webster: stylops broadly: an insect of the order Strepsiptera/ref> have halteres which evolved from a pair of ancestral forewings. Halteres oscillate rapidly along with the wings and operate like vibrating structure gyroscopes: any rotation of the plane of oscillation causes a force on the vibrating halteres by the Coriolis effect. The insect detects this force with sensory organs called campaniform sensilla and chordotonal organs located at the base of the halteres and uses this information to interpret and ...
