Basketball and Shoes The basketball is used in this sport because the ball is supposed to go through a 10 foot high hoop For this sport you have to wear gym shoes or you can slip and fall http://en.wikipedia.org/wiki/Basketball (info) http://www.aitkin.k12.mn.us/sports/RipplesideSports/images/basketball.gif (pic)
4. Basketball A basketball is an inflated ball used in the game of basketball. Nearly all basketballs have an inflatable inner rubber bladder, generally wrapped in layers of fiber and then covered with a tacky surface made either from leather (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small opening to allow the pressure to be increased or decreased. A soccer ball was used before this. http://en.wikipedia.org/wiki/Basketball_(ball) (info & pic)
5. Polymers in Basketballs The polymers improved Basket Balls y giving them a better grip and making them more bouncy then they used to be. http://wellpinitscience.blogspot.com/2008/02/chemistry-of-basketball.html (info) http://ec.europa.eu/health/opinions/en/dental-amalgam/images/polymer.gif (pic)
6. Basketball Shoes The idea of a "sneaker" did not come along until an American inventor, Charles Goodyear, patented the process for the vulcanization of rubber. Before this people wore slippery shoes such as flip-flops. http://en.wikipedia.org/wiki/Athletic_shoe (info) http://www.eurosportsstore.com/img/p/24-66-thickbox.jpg (pic)
7. Polymers In Basketball Shoes The polymers gave shoes more durability, strength and biocompatibility Biocompatibility-the quality of not having toxic or injurious effects on biological systems.biocompatibility http://www.thefreelibrary.com/Material+world:+advances+in+polymers+and+ceramics+have+improved+the...-a0197597847 (info) http://www.instablogsimages.com/images/2009/07/18/bright-walk_2_rJYGR_69.jpg (pic)
8. Football Field From the football made from polyurethane to the football field turf made from polyethylene. Both of these polymers are man-made polymers. Turf helps athletes play better on the field http://blogs.lib.ncsu.edu/chem/entry/polymers_in_sports(info) http://rugs.thefurniture.com/images/JOYC/KDE/1471_FootballFun.jpg (pic)
