Can you bend it like Beckham? With the right training, skill, and knowing more about the soccer ball, the individual will! The soccer ball is a very interesting object. A soccer ball has to have a certain amount of air pressure in order to work properly. The air also affects the soccer ball’s flight. The soccer ball is also made of different kinds of material and has different sizes. In the next couple of paragraphs I will tell you more about a soccer ball and the air pressure.
The first soccer ball was a rubber soccer ball made of pig or ox bladder with leather in the 1800s (The Science of Soccer, 1998). At that time it was difficult to make a regular shaped ball and maintain it while playing. By the 1900s most soccer balls were made of rubber bladder instead of animal bladder. It was found that soccer balls made with animal bladder were harder and wouldn’t lose their shape. Even though it was easier to kick the ball the soccer ball absorbed lots of water if it rained and made the ball very hard which caused head injuries. In the late 1980s the leather casing inside was replaced by artificial casing which was used in most of Europe. In modern day the soccer balls are still made of artificial casing which you can pump air into through a little hole on the top of the casing (FIFA magazine, 1998). An adult soccer ball has a circumference of 25 to 27 inches and weighs 14 ounces. On the other hand a kid’s soccer ball is 24 inches in circumference and weighs a little less than an adult soccer ball (“Soccer”, 2002).

According to Davidhanzy (1998) if a soccer ball is dropped on a hard surface it will bounce back lower than it started. This kind of motion is called the bouncing of the soccer ball. This kind of motion effects how high the soccer ball will bounce. The harder the ball is the higher it will bounce. For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.
The air also affects the flight of a soccer ball. In the air there are little particles known as air molecules. They move around at a certain speed and the amount of air pressure comes when the air molecules are forced against a certain object (NASA, 2004).
Also the amount of air molecules is greater at lower altitudes than at a high altitude. If an air molecule hits another air molecule even more air pressure happens. Air pressure can be felt while riding an express elevator to the top floor of a really...
