Polymers In Tennis

  1. 1. Polymers in Tennis By: Glizyl Luna
  2. 2. What different types of equipment are used in your sport? ● Need a tennis ball ● A tennis racquet ● Tennis shoes ● Tennis court http://www.google.com/webhp?hl=en
  3. 3. A tennis ball and a tennis Racquet ● They use a tennis racquet to hit the ball to other side of the court, going back and forth. ● The tennis ball is used to bounce the ball back and forth until a player misses. http://images.google.com/images? hl=en&rlz=1T4SUNA_enUS277US298&um=1&sa=1&q=someone+playing+tennis&aq=f&oq=&aqi= &start=0
  4. 4. The evolution/history of the tennis racquets ● The first tennis racquets were actually the players hands and gloves to hit the ball. They then evolved into wooden paddles. In the 14th century they had a racquet with strings with a wooden frame. One hundred years later new improvements in technology they had laminating the technology on the racquets. http://tennis.about.com/od/racquetsballsstringing/a/evolmodracquet.htm
  5. 5. Polymers have improved ● The natural “gut” string is the important characteristics of strength, resiliency and surface roughness. The improved string is in the form of a filament of polymer material which is nylon. The result is a racquet string of improved stretch resilience, or resilience under tension. http://www.patentstorm.us/patents/4043555/description.html
  6. 6. The evolution/history of tennis balls ● The tennis balls were made of leather, stuffed with hair or wool. ● Now they are made from rubber and felt that increases the ball's wind resistance and control. http://ezinearticles.com/?Tennis-Balls&id=3168375
  7. 7. Polymers improved in tennis balls  Leather was the first material used.  Now the polymer, polyisoprene are used in the tennis ball cores. http://images.google.com/images? hl=en&rlz=1R2SUNA_enUS346&um=1&sa=1&q=core+of+a+tennis+ball+&aq=f&oq=&aqi=&start=0
  8. 8. Research the football field/outdoor track and how polymers were important. ● On the football field there are polymers which are polyethylene and polyurethane are included in the construction of similar football/track fields around the world.
