Two-handed Throwing
Throwing sports, or throwing games, are physical, human competitions where the outcome is measured by a player's ability to throw an object. The two primary forms are throwing for distance and throwing at a given target or range. The four most prominent throwing for distance sports are in track and field: shot put, discus, javelin, and the hammer throw. Target-based sports have two main genres: bowling and darts, each of which have a great number of variations. History Throwing sports have a long history. Modern track and field comes from a lineage of activities that dates to the Ancient Olympic Games. Artwork from Ancient Greece, in the form of friezes, pottery and statues, attests to the prominence of such sports in the society's physical culture. Bowling games have similarly ancient roots. Games based on throwing stone balls in Ancient Egypt date to 5000 BCE, and a form of bocce is documented in Ancient Rome. The game of catch (throwing and catching an object between play ...

Catch (game)
Catch, or playing catch, is one of the most basic children's games, often played between children or between a parent and child, wherein the participants throw a ball, beanbag, flying disc or similar object back and forth to each other. At early stages in a child's life, having a catch is a good way to evaluate and improve the child's physical coordination.Berry Brazelton, Margaret A. Kenna, ''The Children's Hospital Guide to Your Child's Health and Development'' (2001), p. 224. . Notably, " a child cannot catch a ball that he or she is bouncing, it is unlikely the child will be able to play catch". Most children begin to be able to play catch around the age of four. Many four-year-olds instinctively close their eyes when a ball is heading towards them, and it can take some time to overcome this. Playing catch can help develop dexterity, coordination and confidence. Because playing catch requires at least two participants, and because participants can be substituted at any point d ...

Weight Throw
Two sports have events that fall under the name of weight throw one being the track and field event and the other being the Scottish highland games events. The track and field event is most popular in the United States as an indoor equivalent to the hammer throw event, which can only be held outdoors. The 35 lb weight throw (men) and 20 lb weight throw (women) are not recognised by the International Association of Athletics Federations. The Scottish Highland Games contain two weight throwing events. In the one event the weight, 28 lb or 56 lb, is thrown in a similar manner to a discus. In the other event, the 56 lb weight gets thrown over a bar for height. Weight throw for distance The 56-pound weight throw was conducted twice at the Olympic Games, in 1904 and in 1920.

Overhand Throwing Motion
The overhand (or overhead) throw is a single-handed throw of a projectile where the object is thrown above the shoulder. The overhand throw is a complex motor skill that involves the entire body in a series of linked movements starting from the legs, progressing up through the pelvis and trunk, and culminating in a ballistic motion in the arm that propels a projectile forward. It is used almost exclusively in athletic events. The throwing motion can be broken down into three basic steps: cocking, accelerating, and releasing. Desired qualities in the action produce a fast, accurate throw. These qualities are affected by the physical attributes of the thrower like height, strength, and flexibility. However it is mainly the throwing motion mechanics and the thrower's ability to coordinate them that determines the quality of the throw. Determining the desired qualities of the throwing motion is difficult to assess due to the extremely short amount of time that it takes professionals t ...

Field Of Play
A pitch or a sports ground is an outdoor playing area for various sports. The term ''pitch'' is most commonly used in British English, while the comparable term in American and Canadian English is playing field or sports field. For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likely to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the "foul territory" in baseball. The surface of a pitch is most commonly composed of sod (grass), but may also be artificial turf, sand, clay, gravel, concrete, or other materials. A playing field on ice may be referred to as a ''rink'', for example an ice hockey rink, although ''rink'' may also refer to the entire building or, in the sport of curling, to either the building or a part ...

Pastime
A hobby is considered to be a regular activity that is done for enjoyment, typically during one's leisure time. Hobbies include collecting themed items and objects, engaging in creative and artistic pursuits, playing sports, or pursuing other amusements. Participation in hobbies encourages acquiring substantial skills and knowledge in that area. A list of hobbies changes with renewed interests and developing fashions, making it diverse and lengthy. Hobbies tend to follow trends in society, for example stamp collecting was popular during the nineteenth and twentieth centuries as postal systems were the main means of communication, while video games are more popular nowadays following technological advances. The advancing production and technology of the nineteenth century provided workers with more leisure time to engage in hobbies. Because of this, the efforts of people investing in hobbies has increased with time. Hobbyists may be identified under three sub-categories: ''c ...

Horseshoes (game)
Horseshoes is a lawn game played between two people (or two teams of two people) using four horseshoes and two throwing targets (stakes) set in a lawn or sandbox area. The game is played by the players alternating turns tossing horseshoes at stakes in the ground, which are traditionally placed apart. Modern games use a more stylized U-shaped bar, about twice the size of an actual horseshoe. Game play NHPA Official Rules of the Game of Horseshoes The National Horseshoe Pitchers Association (NHPA), the sport of horseshoes' governing body, maintains a set of rules and their specifications of the game on their website. They outline the style of play, the two most common scoring methods (cancellation and count-all), acceptable equipment, and exact court specifications as well as additional methods of organizing tournament and league competitions. Style of play The game begins with a horseshoe flip to decide who goes first. The winner of the flip throws both horseshoe ...

Pitching Pennies
Pigeon Toss, or in Britain ''Pap'', ''Penny Up'', ''Keeley (Scotland)'', "Nippy (Wales)", Chucks, ''Quarters'', “Tinks” or "Jingies" is a game played with coins. Players take turns to throw a coin at a wall, from some distance away, and the coin which lands closest to the wall is the winner. The history of the game is ancient, and it is known to have been played by Ancient Greek children using bronze coins. In modern Israel the game is also played with Apricot kernel An apricot kernel is the apricot seed located within the fruit endocarp, which forms a hard shell around the seed called the pyrena (stone or pit). The kernel contains amygdalin, a poisonous compound, in concentrations that vary between cult ...s, and is called "Gogoim".

Annulus (mathematics)
In mathematics, an annulus (plural annuli or annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer. The word "annulus" is borrowed from the Latin word ''anulus'' or ''annulus'' meaning 'little ring'. The adjectival form is annular (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder and the punctured plane. Area The area of an annulus is the difference in the areas of the larger circle of radius and the smaller one of radius : :A = \pi R^2 - \pi r^2 = \pi\left(R^2 - r^2\right). The area of an annulus is determined by the length of the longest line segment within the annulus, which is the chord tangent to the inner circle, in the accompanying diagram. That can be shown using the Pythagorean theorem since this line is tangent to the smaller circle and perpendicular to its radius at that point, so and are sides of a right-angled triangle with hypotenuse , and the ar ...

Disk (mathematics)
In geometry, a disk (also spelled disc). is the region in a plane bounded by a circle. A disk is said to be ''closed'' if it contains the circle that constitutes its boundary, and ''open'' if it does not. For a radius, r, an open disk is usually denoted as D_r and a closed disk is \overline. However in the field of topology the closed disk is usually denoted as D^2 while the open disk is \operatorname D^2. Formulas In Cartesian coordinates, the ''open disk'' of center (a, b) and radius ''R'' is given by the formula :D=\ while the ''closed disk'' of the same center and radius is given by :\overline=\. The area of a closed or open disk of radius ''R'' is π''R''2 (see area of a disk). Properties The disk has circular symmetry. The open disk and the closed disk are not topologically equivalent (that is, they are not homeomorphic), as they have different topological properties from each other. For instance, every closed disk is compact whereas every open disk is not compact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dart (missile)
Darts are airborne ranged weapons. They are designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from javelins by the presence of fletching (feathers on the tail) and a shaft that is shorter and/or more flexible. Darts can be propelled by hand or with the aid of a hand-held implement such as a blowgun. They can be distinguished from arrows because they are not used with a bow. Darts have been used since pre-history. The plumbatae were lead-weighted darts thrown by infantrymen in Antiquity and the Middle Ages. Darts can be propelled by a number of means. The atlatl uses leverage to increase the velocity of the dart, the kestros increases the range of propelled darts using a sling, and the exhalation of a person's breath through a blowgun propels small stone points or poisoned needles with pneumatic force. In the modern era, darts have been used for recreation; in lawn darts and the game of darts. History Pre-history Some of th ...

Ball
A ball is a round object (usually spherical, but can sometimes be ovoid) with several uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles. Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see the bouncing rubber balls (although solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials. As balls are one o ...
