Sports.

is an activity that is governed by a set of rules or customs and often engaged in competitively. Sports commonly refer to activities where the physical capabilities of the competitor are the sole or primary determinant of the outcome (winning or losing), but the term is also used to include activities such as mind sports (a common name for some card games and board games with little to no element of chance) and motor sports where mental acuity or equipment quality are major factors. Sport is commonly defined as an organized, competitive and skillful physical activity requiring commitment and fair play. Some view sports as differing from games based on the fact that there are usually higher levels of organization and profit (not always monetary) involved in sports. Accurate records are kept and updated for most sports at the highest levels, while failures and accomplishments are widely announced in sport news.

Tennis:
Tennis is played on a rectangular, flat surface, usually grass, clay, a hard court of concrete and/or asphalt and occasionally carpet (indoor). The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 ft (10.97 m) for doubles matches. Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (91.4 cm) high in the center. The modern tennis court owes its design to Major Walter Clapton Winfield who, in 1873, patented a court much the same as the current one for his stick tennis (sphairistike). This template was modified in 1875 to the court design that exists today, with markings similar to Winfield’s version, but with the hourglass shape of his court changed to a rectangle.


Basketball
is a team sport in which two teams of five active players each try to score points against one another by placing a ball through a 10 foot (3.048 m) high hoop (the goal) under organized rules. Basketball is one of the most popular and widely viewed sports in the world Points are scored by throwing (shooting) the ball through the basket from above; the team with more points at the end of the game wins. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (foul) is penalized and there are restrictions on how the ball can be handled (violations).


Soccer:
Football or soccer is a team sport played between two teams of eleven players using a spherical ball. Association football is the most popular football variant worldwide, and is widely considered to be the most popular sport in the world. The game is played on a rectangular grass or artificial turf field, with a goal in the centre of each of the short ends. The object of the game is to score by driving the ball into the opposing goal. In general play, the goalkeepers are the only players allowed to use their hands or arms to propel the ball; the rest of the team usually use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in midair. The team that scores the most goals by the end of the match wins.
