Wireball
Wireball is a street game related to baseball, usually formed as a pick-up game, in urban areas of the United States. The equipment consists of a pimple or pensie pinkie ball and a convenient place in a street or driveway where an electric power line or group of power lines bisect horizontally. The rules come from baseball and are modified to fit the situation. It can be played with one or more persons per team. Rules Opponents stand facing each other on opposite sides of the wire. Limits of play are defined by agreement, usually the width of the street and landmark in the street such as a manhole cover as the furthest limit of the field. The object of the game is for the “batter” to throw the ball over or hit the wire to get a hit. The fielder must catch the ball before it bounces to make an out. Hits are scored accordingly- a ball thrown successfully over the wire and uncaught is a single. A ball that touches the wire and continues over it is a double. A ball that hits the ...

Pensie Pinkie
A Spalding Hi-Bounce Ball, often called a Spaldeen or a Pensie Pinkie, is a rubber ball, described as a tennis ball core without the felt. These balls are commonly used in street games developed in the mid-20th century, such as Chinese handball (a variation on American handball), Australian Handball, stoop ball, hit-the-penny (involving trying to make a penny flip on a sidewalk), butts up, handball, punchball, boxball, half-rubber, Wireball and stickball (variations of baseball). Name The term arose from a local pronunciation of " Spalding" in Brooklyn, with Spalding being the sporting goods company that produced the balls. The name has become so common that Spalding now uses it in marketing, and it is now a registered trademark. The ball is also known as a "Pensie Pinkie" or "Pennsy Pinky" referring to Penn Racquet Sports, another sporting goods manufacturer brand. History Spaldeens were popular with children from the 1930s through to the 1970s. The balls sold for 15 cents in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variations Of Baseball
Baseball is a bat-and-ball sport that has many recreational variants (sometimes referred to as diamond sports). The major sport most related to baseball is the Olympic discipline of softball, with the two sports being administered internationally alongside Baseball5 (invented in 2017) by the World Baseball Softball Confederation. Many variations of baseball change the game significantly. For example, many variations are played informally, with less equipment/space requirements and a softer ball, and certain variations do not feature a pitcher, and/or have the batters hit the ball using their hands or feet, with failure to legally hit the ball on the first opportunity resulting in an automatic out. There may be a lack of baserunning, with base hits awarded according to the distance or number of bounces the batted ball takes before being fielded, and imaginary " ghost runners" advancing around the bases in lieu of actual runners. Other variations are even more loosely based on base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Game
A street game or street sport is a sport or game that is played on city streets rather than a prepared field. Street games are usually simply play time activities for children in the most convenient venue. Some street games have risen to the level of organized tournaments, such as stickball. When street games are based on organized sports, the rules are highly modified to fit the situation, i.e. manhole covers for bases with cars or buildings for foul lines in stickball. When balls are used in street games, Spaldeens are often used. Street sports Street sports are sports held in urban environments. Street sports are an expression of the spontaneous, improvisational and creative origins of sport adapted by human ingenuity to the urban environment. In historical terms their origins are traceable to the very earliest evidence of sports in Greek and Roman civilisation.''Urbanization and the Evolution of the City; Reader, J.; Vintage; (2005) Street sports are a hybrid form of sp ...

Single (baseball)
In baseball, a single is the most common type of base hit, accomplished through the act of a batter safely reaching first base by hitting a fair ball (thus becoming a runner) and getting to first base before a fielder puts him out. As an exception, a batter-runner reaching first base safely is not credited with a single when an infielder attempts to put out another runner on the first play; this is one type of a fielder's choice. Also, a batter-runner reaching first base on a play due to a fielder's error trying to put him out at first base or another runner out (as a fielder's choice) is not credited with a single. On a single hit to the outfield, any runners on second base or third base normally score, and sometimes the runner from first base is able to advance to third base. Depending on the location of the hit, a quick recovery by the outfielder can prevent such an advance or create a play on the advancing runner. Hitters who focus on hitting singles rather than doubles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trajectory
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a satellite. For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass. In control theory, a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map). In discrete mathematics, a trajectory is a sequence (f^k(x))_ of values calculated by the iterated application of a mapping f to an element x of its source. Physics of trajectories A familiar example of a trajectory is the path of a projectile, such as a thrown ball or rock. In a significantly simplified model, the object moves only under the influence of a uniform gravitational force field. This can be ...

Vertical Direction
In astronomy, geography, and related sciences and contexts, a '' direction'' or ''plane'' passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system. Historical definition The word ''horizontal'' is derived from the Latin , which derives from the Greek , meaning 'separating' or 'marking a boundary'. The word ''vertical'' is derived from the late Latin ', which is from the same root as ''vertex'', meaning 'highest point' or more literally the 'turning point' such as in a whirlpool. Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book ''Perspective''.

Foul (sports)
In sports, a foul is an inappropriate or unfair act by a player as deemed by a referee, usually violating the rules of the sport or game. A foul may be intentional or accidental, and often results in a penalty. Even though it may not be intentional, fouling can still cause serious harm or injury to opposing players, or even their own players if unaware of their surroundings during particular situations on sports. Fouls are used in many different sports. Often own teammates can clash and foul each other by accident, such as both going for and with eyes on a ball in AFL. Strategical fouls violate the traditional norms of cooperation and agreement to the essential rules and regulations of the game, or are perhaps not part of the games at all. Individual sports may have different types of fouls. For example, in basketball, a personal foul involves illegal personal contact with an opponent. A technical foul refers to unsportsmanlike non-contact behavior, a more serious infraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike (baseball)
In baseball, the strike zone is the volume of space through which a pitch must pass in order to be called a strike even if the batter does not swing. The strike zone is defined as the volume of space above home plate and between the batter's knees and the midpoint of their torso. Whether a pitch passes through the zone is decided by an umpire, who is generally positioned behind the catcher. Strikes are desirable for the pitcher and the fielding team, as three strikes result in a strikeout of that batter. A pitch that misses the strike zone is called a ball if the batter doesn't swing. Balls are desirable for the batter and the batting team, as four balls allow the batter to take a "walk" to first base as a base on balls. Definition The strike zone is a volume of space, a vertical right pentagonal prism. Its sides are vertical planes extending up from the edges of home plate. In Major League Baseball, the top of the strike zone is the midpoint between the top of the batter's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple (baseball)
In baseball, a triple is the act of a batter safely reaching third base after hitting the ball, with neither the benefit of a fielder's misplay (see error) nor another runner being put out on a fielder's choice. A triple is sometimes called a "three-bagger" or "three-base hit". For statistical and scorekeeping purposes it is denoted by 3B. Triples have become somewhat rare in Major League Baseball, less common than both the double and the home run. This is because it requires a ball to be hit solidly to a distant part of the field (ordinarily a line drive or fly ball near the foul line closest to right field), or the ball to take an irregular bounce in the outfield, usually against the wall, away from a fielder. It also requires the batter's team to have a good strategic reason for wanting the batter on third base, as a stand-up double is sufficient to put the batter in scoring position and there will often be little strategic advantage to risk being tagged out whilst tr ...
