Physics 173 Internet
Question of the Week
January 26 - January 30, 1998
- Use a major search engine to locate the Exploratorium Web
site. Once you have the Exploratorium web site, use the buttons
from the home page to navigate to the Sports Science section of
the Web site. From the Sports Science page, you will find a link
to an article on the physics of baseball. The article is titled
"How Far Can You Hit One?" and consists of four web pages whose
URLs are titled "../mainstory.html", "../mainstory2.html", etc.
Once you have found the article, do the following:
- Identify the full URL (address) of the first page
of the article.
- Describe the search path which you took to find the page
(see example description).
- Read the full article and respond to the following:
- Describe, discuss and explain in detail the
impact which air density, viscosity, and humidity have upon
the amount of air drag encountered by a baseball during its
flight through the air and the ultimate range of the
- Accompany you discussion by some of the numerical values
provided within the article in order to emphasize your point
about the above relationships.
Do a bang-up job on question #1 since it is worth 2 of the 3
extra credit points.
The article on the physics of baseball makes the
following statement about the motion of a baseball in the absence of
"Say that the ball, struck by
the bat, flies into the air at 165 miles per hour, at an angle of 55
degrees. If the ball were flying through a vacuum, the distance it
would travel would be determined solely by the ability to resist
gravity imparted by its speed and trajectory, and it would travel 799
Use the projectile motion principles, equations and calculations
discussed this week in conjunction with the following conversion
factors to either verify or falsify the above statement. Your
calculations must be completely shown in an organized and clear
fashion to receive full credit.
