Why are tennis balls green?
Well, actually, they aren't. The International Tennis Federation (ITF) categorizes the color as "optic yellow.” Incidentally, tennis balls actually used to be black or white. When tennis started to be televised in color in the late 1960s, it was hard for viewers to track the ball on their screens, so the ITF came up with the bright greenish-yellow to make it easier on their eyes. They're rare today, but according to ITF rules, white tennis balls are technically still allowed—a relic of pre-TV times.

What is a tennis ball made of?
The early tennis ball was "a wad of hair, wool, or cork wrapped in string and cloth or leather." It would have been invented by the people who most likely invented tennis: French monks in the 11th or 12th century. The modern version is a hollow ball, with two different kinds of material covering it: rubber and a fabric. Two similar strips of rubber form the spherical ball and it is then covered by canvas. Tennis balls are made of a layer of rubber surrounding a hollow centre (core). A thin layer of adhesive covers the rubber and then a layer of felt-like material made up of wool and artificial fibers called the nap. The lettering on the surface is just black ink. The ball consists of two rubber hemispheres joined together under pressure ( or using a chemical decomposition process to form internal pressure)so that the 'core' formed has a specified resilience and gives the finished ball its required properties. The fabric (felt) is first woven using cotton as a backing (warp)and a wool / nylon for the covering (weft). After felting the fabric is dyed and finished before transportation to a ball making plant. Two 'dogbones' of fabric are cut after application of a latex backing and stuck to the latex covered core - the 'ball' is then cured and the result is a proper tennis ball. Finally logos are applied and the ball packed under pressure to preserve its internal pressure. Tennis balls used in professional tennis must adhere to ITF and/or USTA rules and regulations (refer to the ITF link, below). One of the rules requires that the ball be either yellow or white, with yellow being the preferred color for better viewing on televisions. For amateur purposes in non-ITF/USTA events, any color is allowed, which is why some retailers sell tennis balls in odd colors, such as pink, green, black, and even multi-tones.

How do tennis net sensors work?
A sensing device is attached directly to the net cable or onto the anchoring cables. The device comprises of an accelerometer which triggers an electrical signal, to the speaker system, when the level of acceleration (m/s2) exceeds given levels. An accelerometer is used in place of a movement sensor because a movement sensor would be set off more regularly by the wind.

Asked in Tennis
Is a forehand tennis drive a closed skill?
In its normal sports setting, it is an open skill, because the circumstances around which you need to hit it change regularly. The skill is also carried out in response to a moving and changing stimulus and situation. The ball needs to be played according to the delivery of one's opponent, and it must then be struck according to the whereabouts and movement of one's opponent - so that the way in which the forehand must be executed can vary quite considerably. Strategy plays a major part. On the other hand, an example of a closed skill might be throwing the discus. One goes through virtually the exact same patterns and is faced with the same major circumstances upon each throw. The action is not one responding to a changing environment as such. The major extraneous factors that the performer has to deal with are nature of the ground's surface and perhaps wind factors. Now, of course, having said that, a tennis forehand could become a closed skill, if one is merely practicing it by oneself, as one might do for (say) tennis serves. The tennis serve, in practice, is more naturally, a closed skill in and of itself. So, if one merely bounces a ball within confortable reach and then plays a forehand shot in practice, this would represent a closed skill.
