Rebound Ace is a cushioned tennis hardcourt composed of polyurethane rubber, fiberglass, and other materials on top of an asphalt or reinforced concrete base. It is manufactured and sold by California Products Corporation's Sports Surfaces division, a company based in Andover, Massachusetts, United States. Properties The friction of the surface of Rebound Ace can be varied by adjusting the amount of sand in the top layer, thereby customising the ball bounce and general speed of the court. Rebound Ace is sometimes compared with DecoTurf, which is used at the US Open, but Rebound Ace is built with more cushioning. Australian Open From 1988 until May 30 2007, Rebound Ace was the official surface of the Australian Open, when it was replaced by Plexicushion, which was in turn replaced by Greenset during 2019.

Tennis
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

Homebush Bay
Homebush Bay is a bay on the south bank of the Parramatta River, in the west of Sydney, Australia.

Other contaminants in the bay include phthalates, lead, polycyclic aromatic hydrocarbons, DDT, and heavy me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
