Comparison Of Association Football And Rugby Union
Comparison of association football (football/soccer) and rugby union (rugby/rugby football/rugger) is possible because of the games' similarities and shared origins. Rugby union has a number of set pieces, such as line-outs, scrums and rucks that do not have direct equivalents in association football. Association football aims at a more open kind of play, and there is not the same differentiation between forwards and backs. Another major difference is that rugby union, unlike association football, has no goal keeper. History of early football The earliest forms of football comprise the common ancestry of both association football and of rugby union. Two of the earliest recorded football type games from Europe include Episkyros from Ancient Greece and the Roman version Harpastum, which similar to pre-codified "Mob Football" involved more handling the ball than kicking it. Other competitive games revolving around the kicking of a ball have been played in a few countries thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Football
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 Football player, players who almost exclusively use their feet to propel a Ball (association football), ball around a rectangular field called a Football pitch, pitch. The objective of the game is to Scoring in association football, score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed Goal (sport), goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world's most popular sport. Association football is played in accordance with the Laws of the Game (association football), Laws of the Game, a set of rules that has been in effect since 1863 and maintained by the International Football Association Board, IFAB since 1886. The game is pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Rugby Board
World Rugby is the governing body for the sport of rugby union. World Rugby organises the Rugby World Cup every four years, the sport's most recognised and most profitable competition. It also organises a number of other international competitions, such as the World Rugby Sevens Series, the Rugby World Cup Sevens, the World Rugby Under 20 Championship, World Under 20 Championship, and the Pacific Nations Cup. World Rugby's headquarters are in Dublin, Ireland. Its membership now comprises 133 national unions. Each member country must also be a member of one of the six regional unions into which the world is divided: Africa, North America, Asia, Europe, South America, and Oceania. World Rugby was founded as the International Rugby Football Board (IRFB) in 1886 by , and , with joining in 1890. , and became full members in 1949. became a member in 1978 and a further 80 members joined from 1987 to 1999.

Pentagon
In geometry, a pentagon () is any five-sided polygon or 5-gon. The sum of the internal angles in a simple polygon, simple pentagon is 540°. A pentagon may be simple or list of self-intersecting polygons, self-intersecting. A self-intersecting ''regular pentagon'' (or ''star polygon, star pentagon'') is called a pentagram. Regular pentagons A ''regular polygon, regular pentagon'' has Schläfli symbol and interior angles of 108°. A ''regular polygon, regular pentagon'' has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°). The diagonals of a convex polygon, convex regular pentagon are in the golden ratio to its sides. Given its side length t, its height H (distance from one side to the opposite vertex), width W (distance between two farthest separated points, which equals the diagonal length D) and circumradius R are given by: :\begin H &= \frac~t \approx 1.539~t, \\ W= D &= \frac~t\approx 1.618~t, ...

Futsal
Futsal is a variant of association football played between two teams of five players each on a court smaller than a football pitch. Its rules are based on the Laws of the Game (association football), Laws of the Game of association football, and it also shares similarities with five-a-side football and indoor soccer. Futsal is played between two teams of five players each, one of whom is the goalkeeper. The players mainly use their feet to propel a ball around the court with the objective of Scoring in association football, scoring goals against the opposing team by moving the ball beyond the goal line into the opposing team's Goal (sports), goal. A futsal match consists of two periods of 20 minutes, and the team that scores more goals wins; an equal number of goals scored results in a Tie (draw)#Association football, draw. Futsal is played with a smaller and heavier ball than association football, and usually indoors on a hardcourt surface marked by lines. The playing surface, ba ...

Team Handball
Handball (also known as team handball, European handball, Olympic handball or indoor handball) is a team sport in which two teams of seven players each (six outcourt players and a Handball goalkeeper, goalkeeper) pass a ball using their hands with the aim of throwing it into the goal of the opposing team. A standard match consists of two periods of 30 minutes, and the team that scores more goals wins. Modern handball is played on a court of , with a goal in the middle of each end. The goals are surrounded by a zone where only the defending goalkeeper is allowed; goals must be scored by throwing the ball from outside the zone or while "diving" into it. The sport is usually played indoors, but outdoor variants exist in the forms of field handball, Czech handball (which were more common in the past) and beach handball. The game is fast and high-scoring: professional teams now typically score between 20 and 35 goals each, though lower scores were not uncommon until a few decades ...

Pressure
Pressure (symbol: ''p'' or ''P'') is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled ''gage'' pressure)The preferred spelling varies by country and even by industry. Further, both spellings are often used ''within'' a particular industry or country. Industries in British English-speaking countries typically use the "gauge" spelling. is the pressure relative to the ambient pressure. Various #Units, units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the International System of Units, SI unit of pressure, the Pascal (unit), pascal (Pa), for example, is one newton (unit), newton per square metre (N/m2); similarly, the Pound (force), pound-force per square inch (Pound per square inch, psi, symbol lbf/in2) is the traditional unit of pressure in the imperial units, imperial and United States customary units, US customary systems.

Mass
Mass is an Intrinsic and extrinsic properties, intrinsic property of a physical body, body. It was traditionally believed to be related to the physical quantity, quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particle, elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple Mass in special relativity, definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure (mathematics), measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the Force, strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is Mass versus weight, not the same as weight, even though mass is often determined by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumference
In geometry, the circumference () is the perimeter of a circle or ellipse. The circumference is the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the Locus (geometry), locus corresponding to the Edge (geometry), edge of a Disk (geometry), disk. The is the circumference, or length, of any one of its great circles. Circle The circumference of a circle is the distance around it, but if, as in many elementary treatments, distance is defined in terms of straight lines, this cannot be used as a definition. Under these circumstances, the circumference of a circle may be defined as the Limit (mathematics), limit of the perimeters of inscribed regular polygons as the number of sides increases without bound. The term circumference is used when measuring physical objects, as well as when considering abstrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphere
A sphere (from Ancient Greek, Greek , ) is a surface (mathematics), surface analogous to the circle, a curve. In solid geometry, a sphere is the Locus (mathematics), set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the center (geometry), ''center'' of the sphere, and the distance is the sphere's ''radius''. The earliest known mentions of spheres appear in the work of the Greek mathematics, ancient Greek mathematicians. The sphere is a fundamental surface in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubble (physics), Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is spherical Earth, often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres rolling, roll smoothly in ...

Rugby Football
Rugby football is the collective name for the team sports of rugby union or rugby league. Rugby football started at Rugby School in Rugby, Warwickshire, England, where the rules were first codified in 1845. Forms of football in which the ball was carried and tossed date to the Middle Ages (see medieval football). Rugby football spread to other Public school (United Kingdom), English public schools in the 19th century and across the British Empire as former pupils continued to play it. Rugby football split into two codes in 1895, when twenty-one clubs from the North of England left the Rugby Football Union to form the Rugby Football League, Northern Rugby Football Union (renamed the Rugby Football League in 1922) at the George Hotel, Huddersfield, George Hotel, Huddersfield, over payments to players who took time off work to play ("broken-time payments"), thus making rugby league the first Football, code to turn professional sport, professional and pay players.
