Table Tennis ball shall be spherical in shape with a diameter of 40mm. The ball shall weigh 2.7 grams. The ball shall be made of celluloid or similar plastics material and shall be white or orange and matt. The international rules specify that the game is played with a sphere having a mass of 2.7 grams (0.095 Oz) and a diameter of 40 mm (1.57 in). The rules say that the ball shall bounce up 24–26 cm (9.4–10.2 in) when dropped from a height of 30.5 cm (12.0 in) onto a standard steel block thereby having a  coefficient of restitution  of 0.89 to 0.92. The choice of ball color is made according to the table color and its surroundings. For example, a white ball is easier to see on a green or blue table than it is on a grey table. Manufacturers often indicate the quality of the ball with a star rating system, usually from one to three, three being the highest grade. As this system is not standard across manufacturers, the only way a ball may be used in official competition is up

Volleyball is one of the most successful and popular competitive and recreational sports in the world. It is fast, it is exciting and the action is explosive. Yet volleyball com­prises several crucial overlapping elements whose complimentary interactions render it unique amongst rally games. The ball shall be spherical, made of a flexible leather or synthetic leather case with a bladder inside made of rubber or a similar material. Its colour may be a uniform light colour, or a combination of colours. Synthetic leather material and colour combinations of balls used in Inter­national Official competitions should comply with FIVB standards. Circumference of ball shall be 65-67 cm and its weight shall be 260-280 g. Inside Pressure shall be 0.30 to 0.325 kg/cm2 (4.26 to 4.61 psi) (294.3 to 318.82 mbar or hPa). All balls used in a match must have the same standards regarding circum­ference, weight, pressure, type, colour, etc. 

Tennis ball shall have a uniform outer surface consisting of a fabric cover and shall be white or yellow in colour. If there are any seams they shall be stitch less. Size of the ball shall be more than 1.975 ounces (56.0 grams) and less than 2.095 ounces (59.4 grams) in weight. Each ball shall have a bound of more than 53 inches (134.62 cm) and less than 58 inches (147.32 cm) when dropped 100 inches (254.00 cm) upon a flat, rigid surface e.g., concrete. Ball Type 1 (fast speed) shall have a forward deformation of more than .195 inches (.495 cm) and less than .235 inches (.597 cm) and return deformation of more than .265 inches (.673 cm) and less than .360 inches (.914 cm) at 18 lb. (8.165 kg) load. Ball Types 2 (medium speed) and 3 (slow speed) shall have a forward deformation of more than .220 inches (.559 cm) and less than .290 inches (.737 cm) and a return deformation of more than .315 inches (.800 cm) and less than .425 inches (1.080 cm) at 18 lb. (8.165 kg) load. T

Tennis Racket is generally made of different types of Materials. Most commonly used materials are Graphite, Aluminum, Boron and Kevlar or the Wood. The vast majority of rackets manufactured today use graphite in one form or another as the base ingredient. Graphite is the technological generation’s equivalent of the trusty laminated wooden racket that was so popular until about the 1970s. Graphite is remarkably strong for its relative light weight. It provides terrific power, as well as good control and feel for the ball. But graphite is best in a composite mixture with any of the various thermoplastic and Fiberglass type resins used today. Boron and Kevlar are the two fibers resemble graphite, but boron and Kevlar are even lighter and stiffer than graphite. These materials are strong, enabling you to hit with a lot of power. But unless they are mixed with other materials, their stiffness can transmit a lot of shock and vibration to your arm and shoulder, especially if you don’t

Hockey stick and possible additions may be made of or contain any material other than metal or metallic components, provided it is fit for the purpose of playing hockey and is not hazardous. The application of tapes and resins is permitted provided that the stick surface remains smooth and that it conforms to the stick specifications. The total weight of the stick must not exceed 737 grams. Hockey stick has a traditional shape and comprises of two identifiable parts, the handle and the head. The entire stick must be smooth and must not have any rough or sharp parts. The handle and head must be of one smooth continuous cross-section. The head must be a ‘J’ or ‘U’ shape the upturned or open end of which is limited by the line. The head must be flat on the left hand side only (the side which is to the player’s left when the stick is held with the open end of the head pointing directly away from the player’s front. The flat playing side of the head of the stick and any continua

A basic table tennis racket (has notions of being called a " paddle " or "bat") is used by  table tennis  players. The table tennis racket is usually made from laminated wood covered with rubber on one or two sides depending on the player's grip. Unlike a conventional " racket ", it does not include strings strung across an open frame. The racket may be of any size, shape or weight but the blade shall be flat and rigid. At least 85% of the blade by thickness shall be of natural wood; an adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller. A side of the blade used for striking the ball shall be covered with either ordinary pimpled rubber, with pimples outwards having a total thickness including adhesive of not more than 2.0mm, or sandwich rubber, with pimples inwards or outwa

Football shall be spherical and made of leather or other suitable material preferably Polyurethane. Circumference of ball shall not be more than 70 cm (28 in) and not less than 68 cm (27 in). Football shall not weigh more than 450 g (16 oz) and not less than 410 g (14 oz) at the start of the match. Pressure in the ball shall be equal to 0.6 – 1.1 atmosphere (600 – 1,100 g/cm2) at sea level (8.5 lbs/sq in – 15.6 lbs/sq in). Always Remember: If the ball bursts or becomes defective during the course of a match, then the match is stopped and shall be restarted by dropping the replacement ball at the place where the original ball became defective, unless play was stopped inside the goal area, in which case the referee drops the replacement ball on the goal area line parallel to the goal line at the point nearest to where the original ball was located when play was stopped. If the ball bursts or becomes defective whilst not in play at a kick-off, goal kick, corner kick, free k

Basketball is a  spherical  inflated  ball  used in  basketball sport . Basketballs typically range in size from very small promotional items only a few inches in diameter to extra-large balls nearly a foot in diameter used in training exercises. Basketball in high school would be about 27 inches in circumference, while an NBA ball would be about 29 inches. The actual standard size of a basketball in the  NBA is 29.5 inches in  circumference Nearly all basketballs have an inflatable inner  rubber  bladder, generally wrapped in layers of fiber and then covered with a surface made either from  leather  (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small opening that allows the pressure to be increased or decreased. The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting  color . An orange surface with  black
