Review of literature
I am going to be doing my science fair project this year on a ball’s rebound height. During this project I will be covering many things. For example, I will be covering the components that make a ball’s rebound height equal or less than its original height. I also will be covering what roles gravitation play in this experiment. In addition to that, during my project, I will be figuring out the history of a basketball and a super ball. Something different about the two balls are that, a basketball is larger than a super ball. I am also going to figure out how they were made and what they are made of. I am going to figure out why a super ball could have a greater rebound height than a basketball. Last but not …show more content…
If so, the ball that that goes the highest most likely goes the highest because of its elasticity. “Elasticity is basically the ability of an object to bend without breaking and then to return to its original shape,” which is stated in the article UCSB Science Line Sqtest(Online). How high a ball bounces depends on the elasticity of the material it’s made out of. Also if it’s a ball that needs inflated the elasticity can depend on how fully inflated the ball is. Without elasticity, balls would probably not bounce near as high as they do with elasticity. Also, elasticity is important because without it we would not be able to play many sports. This would happen because, when the ball hits any surface it would not turn back into its original …show more content…
This basketball just happened to be about 81 cm in circumference. Holmes, Gillian states in his article that “The very first ball was made of laced leather and weighed less than 20 oz(567g.).” Next was a ball that didn’t need laces, this basketball was introduced in 1948 this ball was 76 cm. Today, basketballs are about 75-78 cm. The outside cover of a basketball is made of synthetic rubber, rubber, composition(an aggregate material made from two or more substances) or leather. Fromm, James stated that “Synthetic rubber, a polymer of isoprene, was achieved almost simultaneously in 1955 by several major rubber manufacturers using different catalysts, Natural rubber is a polymer found in the sap of the rubber tree, Hevea brasiliensis, originally native to Brazil” so these two rubbers do differentiate. The inside of a basketball contains a bladder, which is a balloon-like structure that holds the air when you inflate the basketball. The inside of a basketball also contains a carcass. The bladder of a basketball is made of butyl rubber( a polymer with unique physical and chemical properties) this is significant enough to fit in a basketball because it is an inner liner, the carcass has thread pieces that are made of nylon or polyester, which is also stated by Holmes, Gillian. This layer of thread insulates the area between the cover of the ball and the bladder. This
