The company was founded in 2007 by Chris Ruder and is based in Chicago, Illinois — with employees all over the country. Spikeball Roundnet Association tournaments began airing on ESPN2 in May 2018. History The company was incorporated in 2007 and in 2008 began selling equipment for roundnet, a net sport that had been invented in the 1980s by Jeff Knurek, an American toymaker who did not patent it. Roundnet, as the game is now known, is played with a small trampoline-like net placed on the ground between two teams with two players each who bounce a ball back and forth on the net, in a gameplay that has been compared to volleyball. Ruder had purchased a set when it was originally marketed, briefl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crossnet
Crossnet (also known as CROSSNET) is an American sports equipment company that produces a four-way volleyball game of the same name. Crossnet is a combination of volleyball and four square, in a competitive game. History In 2017, the game was devised in the farm town of Woodstock, Connecticut by brothers Chris and Greg Meade and their childhood friend Mike Delpapa, with inspiration from KanJam and four square. Chris said in interview that, to some degree, the motivation he and his brother had to create the company came from the experience of losing their father in 2012.

Deuce (tennis)
This page is a glossary of tennis terminology. A * Ace: Serve where the tennis ball lands inside the '' service box'' and is not touched by the receiver; thus, a shot that is both a serve and a winner is an ace. Aces are usually powerful and generally land on or near one of the corners at the back of the service box. Initially, the term was used to indicate the scoring of a point. * Action: Synonym of ''spin''. * Ad court: Left side of the court of each player, so called because the ''ad'' (''advantage'') point immediately following a deuce is always served to this side of the court. * Ad in: '' Advantage'' to the ''server''. * Ad out: '' Advantage'' to the '' receiver''. * Ad: Used by the chair umpire to announce the score when a player has the '' advantage'', meaning they won the point immediately after a '' deuce''. See scoring in tennis. * Advantage set: Set won by a player or team having won at least six games with a two-game advantage over the opponent (as opposed to ...

Tennis
Tennis is a List of racket sports, racket sport that is played either individually against a single opponent (singles (tennis), singles) or between two teams of two players each (doubles (tennis), doubles). Each player uses a tennis racket strung with a cord to strike a hollow rubber tennis ball, ball covered with felt over or around a net and into the opponent's tennis court, court. The object is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. If a player is unable to return the ball successfully, the opponent scores a Point (tennis), point. Playable at all levels of society and at all ages, tennis can be played by anyone who can hold a racket, including Wheelchair tennis, wheelchair users. The original forms of tennis developed in France during the late Middle Ages. The modern form of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections to various field (lawn) games such as croqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Table Tennis
Table tennis (also known as ping-pong) is a racket sport derived from tennis but distinguished by its playing surface being atop a stationary table, rather than the Tennis court, court on which players stand. Either individually or in teams of two, players take alternating turns returning a light, hollow ball over the table's net onto the opposing half of the court using small table tennis racket, rackets until they fail to do so, which results in a point for the opponent. Play is fast, requiring quick reaction and constant attention, and is characterized by an emphasis on spin, which can affect the ball's trajectory more than in other ball sports. Owed to its small minimum playing area, its ability to be played indoors in all climates, and relative accessibility of equipment, table tennis is enjoyed worldwide not just as a competitive sport, but as a common recreational pastime among players of all levels and ages. Table tennis has been an Table tennis at the Summer Olympics, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net And Wall Games
Net and wall games are court games where either a net separates the opponents or a wall serves to reflect the ball to the opponent. The object of these games is to hit or throw the ball or bird over the net or against the wall back to the opponent. Play typically begins with one side ''serving'' the ball/bird by initially tossing or releasing it and then hitting/throwing it over the net or to the wall. This then starts a ''rally'', in which the sides alternate hitting/throwing the ball/bird. Players then score points whenever the opponent fails to return the ball/bird back. The criteria on what is considered a valid return varies between each sport (such as the number of times the ball may be touched or bounced on a player's side before it must go back). Sports like Real tennis, Padel and Wallyball use both net and walls. Some sports like Four square, Ballon au poing, Tamburello and Roundnet has the same logic of wall games using the floor or trampoline in the rebounding funct ...

Bouncing Ball
The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high school or undergraduate level physics courses. However, the exact modelling of the behaviour is complex and of interest in sports engineering. The motion of a ball is generally described by projectile motion (which can be affected by gravity, drag, the Magnus effect, and buoyancy), while its impact is usually characterized through the coefficient of restitution (which can be affected by the nature of the ball, the nature of the impacting surface, the impact velocity, rotation, and local conditions such as temperature and pressure). To ensure fair play, many sports governing bodies set limits on the bounciness of their ball and forbid tampering with the ball's aerodynamic properties. The bounciness of balls h ...
