some facts about tennis and basketball

1. Equipment
The right equipment is essential for a good game of tennis, along with
demarcation of the court according to international standards. Here are the
specifications.
The Tennis Court
Tennis is required to be played in a regulation size tennis court. This means that it
has to be 78 feet long (23.77 m) and 27 feet (8.23 m) wide (for singles matches) or
36 feet (10.97 m) wide (for doubles matches). The court must have a 3 feet (0.914
meter) high net (with 3 ½ feet net posts), dividing it down the center. The type of
court floor varies. It may be asphalt, clay, concrete, grass, artificial grass, wood or
made of other synthetic materials. The parallel line at both ends of the court,
which marks its border, is known as a 'baseline', while the line marking the side of
the court is known as 'sideline'.
A line parallel to the baseline, known as 'server line', is marked at a distance of 21
feet from the net, on either side. The center line, which is perpendicular to the
net, is drawn halfway between the sidelines and exactly divides the courts into
two halves on either side. Moreover, the server line and the center line on either
side, divides each side of the court into four quarters. The quarter courts near the
net are known as 'service courts'.
Tennis Rackets
The usual tournament size racket should not be more than 29 inches in length and
12.5 inches in width. The hitting area of the racket cannot be more than 15.5
inches long and 11.5 inches wide.

2. Tennis Balls
These vary in color, but for official tournaments the ball must be yellow or white in
color. Two, three, four or six balls may be used in a match.
Singles Game Basics
The server is chosen by a coin toss. The player who wins the toss can choose to
serve or choose the side he wants. If the toss winner chooses to serve, his
opponent gets to choose the side and vice versa. This applies to both singles and
doubles games. In singles, the server (person playing first) and receiver (one who
receives the serve) change position (left/right), after every point and the ends are
changed after every odd numbered game.
Doubles Game Basics
serving is alternated from team to team and from player to player so that each
player serves every fourth game. Both partners (receivers and servers) can stand
anywhere they want, however it is traditional for partners to stand side by side.
The order of serving needs to be decided before the first game of any set begins.
Scoring
a match can either be 'Best of Three Sets (First player to win 2 sets, wins the
match) ' or 'Best of Five Sets (First player to win 3 sets, wins the match)'. A player
wins a set, when he wins 6 games, provided he is ahead of his opponent by two
games. If the difference between the players is less than 2 games, the game may
continue till either wins the set by a margin of two (known as the Advantage set
scoring method).
The Rules
Basketball is a team sport. Two teams of five players each try to score by shooting
a ball through a hoop elevated 10 feet above the ground. The game is played on a
rectangular floor called the court, and there is a hoop at each end. The court is
divided into two main sections by the mid-court line. If the offensive team puts
the ball into play behind the mid-court line, it has ten seconds to get the ball over
the mid-court line. If it doesn't, then the defense gets the ball. Once the offensive

ball in the area in back of the line. If it does, the defense is awarded the ball.
FOULS
Personal fouls: Personal fouls include any type of illegal physical contact.
Hitting
Pushing
Slapping
Holding
Illegal pick/screen -- when an offensive player is moving. When an offensive
player sticks out a limb and makes physical contact with a defender in an
attempt to block the path of the defender.
Player Positions
Center. Centers are generally your tallest players. They generally are positioned
near the basket.
Offensive -- The center's goal is to get open for a pass and to shoot. They are also
responsible for blocking defenders, known as picking or screening, to open other
players up for driving to the basket for a goal. Centers are expected to get some
offensive rebounds and put-backs.
Defensive -- On defense, the center's main responsibility is to keep opponents
from shooting by blocking shots and passes in the key area. They also are expected
to get a lot of rebounds because they're taller.
Forward. Your next tallest players will most likely be your forwards. While a
forward may be called upon to play under the hoop, they may also be required to
operate in the wings and corner areas.
Offensive -- Forwards are responsible to get free for a pass, take outside shots,
drive for goals, and rebound.

4. Scoring
In basketball, there are about 3 different ways to score: free throws (1 point), field
goals (2 points), and 3 pointers (nuff said). Anything made within the big arch is
considered a field goal (jumper/J). If you are fouled (forceful physical contact
which could inhibit a shot) while shooting a field goal, you get a free throw. You
get two free throws (made from the mark right in front of the goal) if you miss the
shot, and one if you made the shot, making a three point play. If you shoot a 3,
and make it, and get fouled, you could have the chance at making arguably the
most points in one play, 4 (a 3 pointer plus a free throw).
