Table Tennis
Table Tennis, also known as Ping Pong, is a sport where two players hit a lightweight, hollow ball back and forth with paddles. It originated from England in the Victorian era and was made an Olympic sport in 1988.

Why is a golf ball heavier than a table-tennis ball even though the balls are the same size?
Because the table-tennis ball is hollow on the inside and made of a lighter weight celluloid, while the golf ball is made of a hard outer shell of plastic with rubber compacted on the inside. The golf ball is denser, meaning it has more mass per volume (since they're the same size), so it is heavier.
Ball
The international rules specify that the game is played with a light 2.7 gram, 40 mm (formerly 38 mm) diameter ball. Generally, it is the most-used ball. The ball is required to have a coefficient of restitution (the ball will only bounce a certain percentage of what it did last time, in this case 94%) of 0.94. The 40 mm ball was introduced after the 2000 Olympic Games. However, this created some controversy as the Chinese National Team argued that this was merely to give non-Chinese players a better chance of winning. A 40 mm table tennis ball is slower and spins less than a 38 mm one. The ball is made of a high-bouncing gas-filled celluloid ball, colored white or orange, with a matte finish. 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. A star on the ball indicates the quality of the ball. 3 stars indicates that it is of the highest quality.
TableDiagram of a table tennis table showing the official dimensionsThe table is 2.74 m (9 ft) long, 1.525 m (5 ft) wide, and 76 cm (30 inch) high with a Masonite (a type of hardboard) or similarly manufactured timber, layered with a smooth, low-friction coating. The table or playing surface is divided into two halves by a 15.25 cm (6 inch) high net.[5]
RacketPlayers are equipped with a wooden blade covered with rubber on one or two sides depending on the grip of the player. This is called either a paddle, racket or bat depending on where in the world the game is being played. In the USA the term "paddle" is common, in Europe the term is "bat," and the official ITTF term is "racket." This section will use the ITTF term.Table tennis regulations allow different surfaces on each side of the racket. The different types of surfaces provide various levels of spin or speed, or in some cases, nullify spin. For example, a player may have a rubber that provides much spin on one side of his racket, and no spin on the other side of the racket. By flipping the racket in play, different types of returns are possible. To help a player distinguish between different types of rubber used by his opposing player, international rules specify that one side must be red while the other side must be black. The player has the right to inspect his opponent's racket before a match to see the type of rubber used and what color it is. Despite high speed play and rapid exchanges, a player can see clearly what side of the racket was used to hit the ball.
Recent years have seen an advancement in technology of table tennis blades. Materials of different properties may be combined with the wood in the blade to enhance its playing performance. Many blades today feature one or more carbon layers within them to enhance their 'sweet spot', and to give the player a greater margin of error when playing powerful shots. Materials incorporated into table tennis blades today include titanium, acrylate, aramids, and aluminium.
The rubber coating may be of pimpled rubber, with the pimples outward, or it may be a rubber that is composed of two materials, a sponge layer, covered by a pimpled rubber, with the pimples pointed inwards or outwards. Some rackets are not covered with rubber at all, because a "naked" racket is believed to be more resistant to a spin. However, it is illegal to use these types of racket in competition as they are not approved by the ITTF. Some types of rubbers are also not approved. Approved rubbers have the ITTF emblem on the base of the rubber.
Players have many choices and variations in rubber sheets on their racket. Although a racket may be purchased with rubber by the manufacturer, most serious tournament players will create a customized racket. A player selects a blank blade (i.e. a racket without rubber), based on his playing style. The type of wood and synthetic layers used to make up the blade will provide a slower or faster blade. The player can choose from different types of rubber sheets which will provide a certain level of spin, speed and specific playing characteristics.
Normally, a sheet of rubber is glued to a blade using rubber cement and not removed until the rubber wears out or becomes damaged. In the 1980s, a new technique was developed where the player would use a special glue called speed glue to apply the rubber every time he played. The glue would help provide more spin and speed by providing a "catapult" effect. This technique is known as "regluing" and has become a standard technique for top players.
The surface of a racket will develop a smooth glossy patina with use. The rubber surface needs to be regularly cleaned to ensure it retains a high friction surface to impart spin to the ball. Players use a commercial cleaner, or just water and detergent as cleaning agents.
Racket construction and new rubber technology (skilled elite players typically select and attach the rubber to their own rackets and glue them before every match) contribute significantly to the amount of deviation from the expected ball flight path. The fairly recent development of speed glue speeds up the departure of the ball from the rubber considerably, though at the cost of some ball control on touch shots where little or no spin is put on the ball.Different types of rubber sheets
- Inverted (non-Chinese): This is the most widely used rubber type. The surface is smooth, with the pimpled side facing inwards toward the blade. This enables the player to generate high levels of spin and speed. Spin is generated not by the action of the topsheet alone, but also by the ball sinking into the sponge and allowing greater surface area to contact the ball.
- Inverted (Chinese): Chinese rubbers typically have stickier (or "tackier") topsheets. Spin is generated mainly by the topsheet, as opposed to the sponge, which is more condensed and firm. The result is usually a far better short game and potential offensive capabilities than normal inverted, but also a less consistent defensive and/or counter play.
- Short pimples (or "pips"): Short pimples-out rubbers are usually used by close-to-the-table hitters (for example, Liu Guoliang). They do not generate as much spin as inverted rubbers, but also make the user less susceptible to the opponent's spin. Speed generated from a short pip rubber is generally greater than that of an inverted with the same sponge. Depending on the thickness of the sponge it is also possible to play a chopping game with short pimples by varying the spin of the return. Whilst blocking and attacking a "dead ball" effect is often noticed. Ding Song is an exponent of this style.
- Long pimples (or "pips"): Long pimples-out rubbers carry relatively long and soft pips. They do not have the ability to generate any real spin of their own, but feed off of the opponent's spin instead. This allows the user to confuse the opponent and upset their rhythm. Long pips rely on the opponent's oncoming spin, as they tend to "continue" the opponent's spin, by bending upon impact, rather than reversing or changing the spin, like inverted rubbers. Long pips are usually used by close-to-the-table blockers, or choppers, but, in some cases, they can be used away from the table for long distance chops. They are usually only used on the backhand side, as they offer very limited attacking capabilities. Depending on the grip of the sides of the pimples and the thickness of the sponge it is also possible to play an aggressive game with long pips, although without much spin capability.
- Anti-spin: Anti-spin rubbers may look similar to the inverted ones, but their surfaces are very slick and frictionless. Like long pimples, they cannot generate much spin. Anti-spin is also not very susceptible to the opponents oncoming spin, due to the low coefficient of friction of the rubber's surface, as well as the incredibly soft sponge, which is designed to cushion or absorb the momentum of the ball upon impact. This is also used to confuse the opponent, but is not widely used at the international level.
What are the dimensions of a ping pong paddle?
The Official Laws of Table Tennis state that a table tennis racket (ping pong paddle) can be of any size, shape or weight.
The rules also state that the blade must be flat and rigid with at least 85% of it (by thickness) made of natural wood.
Most rackets are actually all very similar in size - about 15cm (6 inches) across and 25cm (10 inches) long, including the handle.
What falls faster a marble or a ping pong ball?
in a vacume they are the same obviously. this question is relative to wind factors, and the precise timing mechanics of letting them "go" out of robtic controlled arm from a dcs computer, and to verify with sensitive laser continuty sensors. This actually has to be performed in a lab, and on earth, and in a facility which the time of day, temperature in the lab, atmospheric specifications, and world global physics are recorded at the instant the two figures/objects are dropped. I hope this help you. btw you are asking a question that need real time physical experimentation. it is like asking me if i flip this coin(i.e. a penny) will i get heads or tails. You have to come up with the resources, and perform the experiment your self. In otherwords...what I am "saying" go pull an experiment.
Are you allowed lets in table tennis?
Yes... each time the ball hits the net, on serve, and hits the other side, it is a let.
What is the ceiling height for indoor table tennis?
The minimum height should be 3 metres (10 feet), but for top International matches and tournaments it must be a minimum of 5 metres (16 feet 6 inches).
If you're playing just for fun, at home or anywhere else, it can be whatever you have available.
A table tennis table is...
9 feet (2.74m) long,
5 feet (1.525m) wide and
2 feet 6 inches (76cm) high
... and the net is
6 feet (1.83m) long and
6 inches (15.25 cm) high
When serving in tennis can the ball go off the sides of the table?
If you are playing singles in table tennis, the ball can hit any part of your opponent's half of the table after passing over the net.
As long as the ball hits the playing surface, the service will be legal. The white lines are part of the playing surface.
However, if the ball touches the net during service, before touching the playing surface, the service must be replayed.
But if you're playing doubles, the service must only touch the right half court.
The only instance where the ball must go between your opponents corners of the table is if the receiver is a wheelchair user, then the service must exit between the two corners on his side.
Who invented the first table tennis?
The game of table tennis has its roots in lawn tennis.
When lawn tennis became very popular in the 1870s & 1880s, game makers tried to emulate its success by developing indoor versions of the game.
So there were card games, board & dice games, rackets & balloon games and even tiddledy winks tennis games.
But the first use of the name Table Tennis occurred on a board and dice game by J.H.Singer of New York around 1884 and it's also known that a game of Table Tennis was offered in the 1887 game catalogue of George S. Parker, founder of the famed Parker Brothers in America.
But the first action game of tennis on a table was in 1890, so it was David Foster of England who is the founder/inventor of table tennis in 1890.

How many points do you need to win a tennis game?
Until 2001 a table tennis game was played up to 21 points.
But in order to make the game more exciting, have more "crucial" points, and make it more appealing to television viewers, the rules of table tennis were changed.
A game of table tennis is now played up to 11 points.
The winner is the player or pair who first scores 11 points, unless both players or pairs score 10 points (called deuce). Then a game will be won by the first player or pair to gain a two point lead.
A match is the best of an odd number of games - usually 3, 5 or 7 games.
How much does a ping pong table weight?
Not to be obscure, but what kind of table do you mean? A commercial, aluminum folding table is reasonably light, while a homebuilt table with an inch-thick composite wood top and 2x4 legs and braces takes two men and several children to move.

What are the roles and responsibilities of table tennis officials?
The top official is the Tournament Referee.
The role of a tournament referee differs widely from one Association to another and from one tournament to another.
At one extreme he or she is involved in every part of the organisation, from drafting the entry form to arranging the finals.
At the other extreme, the referee appears only on the day of the tournament solely to decide any question of rule interpretation.
For each match there is an umpire, whose primary duty is to decide the result of each rally.
He is also required to exercise judgment in applying some laws and regulations, such as deciding whether a rally should be a let because a player's service or return may have been affected by circumstances outside the player's control, or whether a player's behaviour is acceptable.
An assistant umpire is solely responsible for decisions on edge balls at the side of the table nearest to him, and he has the same power as the umpire to decide the legality of a player's service action, whether a player obstructs the ball and some of the conditions for a let.
How many points do you have to win to win a Table tennis game?
Games in table tennis are now played first to 11 with a two point margin, or more. 10-10 is now duce. Alternate serves one at a time until there is a two point margin. Also, matches are now usually best of 5 or best of 7 in the finals or international competition.

Do you have to throw the ping pong in the air before serving?
Good question...and the answer is "No". In order for your opponent to score, they must make the ball hit your side once. You lose the point if you hit it before it bounces once on your side, having not yet passed the end, or side lines, of the table.
A ping pong ball weighs about one tenth of an ounce how many ping pong balls together weigh 1 pound?
According to a contribution elsewhere on WikiAnswers, the international official mass of a
ball (they're very sensitive about that) is 2.7 grams = 2.7 x 10-3 kg.
The mass of the earth is listed in another source as 5.97 X 1024 kg.
(5.97 x 1024) / (2.7 x 10-3) = 2.211 x 1027 balls. (rounded)
You were probably looking forward to the thrill of seeing the big number, so here it is:
2.211 x 1027 = 2,211,000,000,000,000,000,000,000,000 balls. (rounded)

What rules is the answer for can you lose a game in ping pong if it's the last point?
The official rules of table tennis state that you have two serves, and then your opponent has two serves.
However, if the score reaches 10-10, each player has only one serve each until the game is won by two clear points.
So if you happen to be serving last at game/match point ... all the better!
Why does a table tennis racket has only black and red colors?
Professional players usually glue their own special rubbers on each side of the racket and different rubbers have different effects on the ball. Its regulation to have a black rubber on one side of the racket and red on the other side so that the opponent can tell what kind of rubber the player hit the ball with. (Players usually inspect their opponents rackets before the match begins to determine what kind of rubber is used on each side of their racket)
