ABSTRACT
In order to start this
project I first researched everything about the average golf ball. I
did this primarily through the Internet. I searched through
www.metacrawler.com, where I was able to find thousands of
sources. Through metacrawler, I was able to connect to other search
engines such as www.altavista.com and www.yahoo.com. From the Internet, I was able to download
tons of pictures on the cores of the golf balls.
Then, to actually get the
materials, I went to a plastics store and bought a three foot long,
three inch in inner diameter acrylic tube. You should make sure that
the tube is acrylic, not just plastic because I later learned that
the plastic becomes deformed as the air is sucked out of the tube. I
also bought a plastic rod and a rubber grommet that fit tightly
around the rod. Along with that, I bought four disks made out of the
same material as the tubing. Out of one of the disks I cut a small
piece of the disk off. I attached this piece to the end of the rod
and put it inside the tube. This is the platform for which the ball
rests before it is dropped.
After all the materials
had been bought, I assembled everything very carefully. Then I
started the experimenting. I first recorded the data for how high the
bounce of the golf ball was without the air sucked out. I repeated
that four times. Then I tested the height of the bounce of the golf
ball with the air sucked out. With the air sucked out, I tested it
four times. I recorded the results for both types of tests.
