Glossary
A glossary (from grc, γλῶσσα, ''glossa''; language, speech, wording) also known as a vocabulary or clavis, is an alphabetical list of Term (language), terms in a particular domain of knowledge with the definitions for those terms. Traditionally, a glossary appears at the end of a book and includes terms within that book that are either newly introduced, uncommon, or specialized. While glossaries are most commonly associated with non-fiction books, in some cases, fiction novels may come with a glossary for unfamiliar terms. A bilingual glossary is a list of terms in one language defined in a second language or Gloss (annotation), glossed by synonyms (or at least near-synonyms) in another language. In a general sense, a glossary contains explanations of concepts relevant to a certain field of study or action. In this sense, the term is related to the notion of ontology. Automatic methods have been also provided that transform a glossary into an ontology or a computational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lob (tennis)
A lob in tennis involves hitting the ball high and deep into the opponent's court. It can be used as an offensive or defensive weapon. History A lob is usually hit when an opponent is standing near the net, waiting to volley. The ball should pass over the opponent and into the open court behind. A good offensive lob cannot be reached by the opponent, yet it is low enough and has enough pace and spin so that the opponent can not run back and chase it down. It can win the point outright, although with some risks involved. Topspin greatly enhances the effectiveness of an offensive lob but also makes the stroke more difficult. When executing the lob, players usually hit the ball at an angle between 0 degrees (flat) and 45 degrees (diagonal). Some players, such as Andre Agassi, Michael Chang, Andy Murray and Lleyton Hewitt, have developed good offensive lobs. A defensive lob requires the opponent to retreat to the ''baseline'' and prolongs the point. When a player is out of court, ...

USA Pickleball
USA Pickleball, or USAP, is the de facto governing body for the sport of pickleball in the United States. It was the world's first national pickleball organization established when it was formed in 1984 as the United States Amateur Pickleball Association. It reorganized as the USA Pickleball Association (USAPA) in 2005. The organization adopted the name USA Pickleball in 2020. As the USAPA, the organization published the first official pickleball rule book in 1984 and published the ''USA Pickleball Association Official Tournament Rulebook'' in 2008. Since 2005 the organization has operated as a nonprofit 501(c)(3) organization. History The ''United States Amateur Pickleball Association'', originally abbreviated U.S.A.P.A., was founded by Bryon Olson, Sid Williams and a few other Washington state pickleball enthusiasts in 1984 in Tacoma, Washington. A few years later Williams changed the name of the organization to the ''United States of America Pickleball Association''. Their ob ...

Tweener (tennis)
The tweener or between-the-legs shot (also known as a hotdog) is a difficult tennis shot where a player hits the ball between his or her legs. It is typically performed facing away from the opponent, when the player attempts to recover a lob and has no time to turn back around, and hits the ball backward between their legs. Forward-facing tweeners, sometimes called "front tweeners", are also occasionally employed. In competitive matches the tweener is a crowd-pleasing, seldom used last resort, but it is a common trick shot in exhibitions. Players who famously executed the backward shot include the pioneer Guillermo Vilas (whose version was called the "Gran Willy"), Yannick Noah, Ilie Năstase, Gabriela Sabatini (whose version became known as "the Sabatweenie"), Roger Federer, Rafael Nadal, Juan Martín del Potro, Nick Kyrgios, Daria Kasatkina, Agnieszka Radwańska, Simona Halep and Novak Djokovic. History The first tennis player to study and develop this shot was Argentine Guill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English (cue Sports Term)
The following is a glossary of traditional English-language terms used in the three overarching cue sports disciplines: ''carom billiards'' referring to the various games played on a billiard table without ; ''pool'', which denotes a host of games played on a table with six pockets; and ''snooker'', played on a large pocket table, and which has a sport culture unto itself distinct from pool. There are also games such as English billiards that include aspects of multiple disciplines. Definitions and language The term "" is sometimes used to refer to all of the cue sports, to a specific class of them, or to specific ones such as English billiards; this article uses the term in its most generic sense unless otherwise noted. The labels "British" and " UK" as applied to entries in this glossary refer to terms originating in the UK and also used in countries that were fairly recently part of the British Empire and/or are part of the Commonwealth of Nations, as opposed to US (and, oft ...

Topspin
In ball sports, topspin or overspin is a property of a ball that rotates forwards as it is moving. Topspin on a ball propelled through the air imparts a downward force that causes the ball to drop, due to its interaction with the air (see Magnus effect). Topspin is the opposite of backspin. Baseball In baseball, the curveball, a type of pitch which usually has downward movement, is thrown in such a way as to put topspin on the ball. Its close relatives are the slider and the slurve. The "curve" of the ball varies from pitcher to pitcher. Cue sports In snooker, pocket billiards and billiards, players use topspin to keep the cue ball moving, including after it hits other balls. They get top spin by hitting the cue against the top of the ball. Cricket In cricket, a top-spinner is a type of delivery bowled by a cricketer bowling either wrist spin or finger spin. In either case, the bowler imparts the ball with top spin by twisting it with his or her fingers prior to delivery. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backspin
In racquet sports and golf, backspin or underspin refers to the reverse rotation of a ball, in relation to the ball's trajectory, that is imparted on the ball by a slice or chop shot. Backspin generates an upward force that lifts the ball (see Magnus effect). While a normal hit bounces well forward as well as up, backspin shots bounce higher and less forward. Backspin is the opposite of topspin. In racket sports, the higher bounce imparted by backspin may make a receiver who has prepared for a different shot miss or mis-hit the ball when swinging. A backspin shot is also useful for defensive shots because a backspin shot takes longer to travel to the opponent, giving the defender more time to get back into position. Also, because backspin shots tend to bounce less far forward once they reach the opposite court, they may be more difficult to attack. This is especially important in table tennis because one must wait for the ball to bounce before hitting it, whereas in tennis the ...

Magnus Effect
The Magnus effect is an observable phenomenon commonly associated with a spinning object moving through a fluid. The path of the spinning object is deflected in a manner not present when the object is not spinning. The deflection can be explained by the difference in pressure of the fluid on opposite sides of the spinning object. The Magnus effect is dependent on the speed of rotation. The most readily observable case of the Magnus effect is when a spinning sphere (or cylinder) curves away from the arc it would follow if it were not spinning. It is often used by association football and volleyball players, baseball pitchers, and cricket bowlers. Consequently, the phenomenon is important in the study of the physics of many ball sports. It is also an important factor in the study of the effects of spinning on guided missiles—and has some engineering uses, for instance in the design of rotor ships and Flettner aeroplanes. Topspin in ball games is defined as spin about a ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation Around A Fixed Axis
Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession. According to Euler's rotation theorem, simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time, a new axis of rotation will appear. This article assumes that the rotation is also stable, such that no torque is required to keep it going. The kinematics and dynamics of rotation around a fixed axis of a rigid body are mathematically much simpler than those for free rotation of a rigid body; they are entirely analogous to those of linear motion along a single fixed direction, which is not true for ''free rotation of a rigid body''. The expressions for the kinetic energy of the object, and for the forces on the parts of the object, are also simpler for rotation around a fixed axis, than for ...

Smash (tennis)
A smash in tennis is a shot that is hit above the hitter's head with a serve-like motion. It is also referred to as an overhead. A smash can usually be hit with a high amount of force and is often a shot that ends the point. Most smashes are hit fairly near the net or in mid-court before the ball bounces, generally against lobs that have not been hit high enough or deep enough by the opponent. A player can also smash a very high ball from the ''baseline'', generally on the bounce, although this is often a less forceful smash. ''Smash'' commonly refers to the forehand smash; backhand smashes are rarer and more difficult to execute, especially for beginners, since they are basically high backhand volleys generally hit at an exact angle causing the ball to spin. Rod Laver and Jimmy Connors, both left-handers, were known for their very powerful backhand smashes. The forehand smash was first used in Tennis by Helena Rice on championship point in the 1890 Wimbledon Championships final ...

Rally Scoring
In sport, score is a Quantity, quantitative measure of the relative performance of opponents in a sporting discipline. Score is usually measured in the abstract unit of ''points'', and events in the competition can raise or lower the score of the involved parties. Most games with score use it as a quantitative indicator of success in the game, and in competition, a goal is often made of attaining a better score than one's opponents in order to win. In team sport, the most common point Performance metrics, metric is the "Goal (sport), goal" or "score". Goals are accrued by the respective teams, and the match score represents the total score accrued by each team. For example, in association football and hockey goals are achieved by putting the ball in the opposing team's net. Other team sports like Rugby football, rugby, baseball and cricket have more complicated scoring procedures. The winning team is that which has recorded the best score, usually the team with the higher total ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
