Physics 173 Internet
Question of the Week
May 11 - May 15, 1998
This week's Internet search question of the week pertains to the
topic of roller coasters. Use a major search engine
Dogpile, etc.) to find a site
titled Roller Coaster Physics by Tony Wayne. (If you still cannot
find the page, you will likely find a link from a GBS page - visit
the Project Corner, click Year-End Projects, click on the Physics
of Roller Coasters, click on a page full of WWW links, and
look for the Physics of Roller Coasters link.) This site is
written by a high school physics teacher for high school physics
students; it details the physics of roller coaster rides.
Once you have found the site, do the
following (1.5 pt.):
- Identify the URL (address) of the page.
- Describe the search path which you took to find the page
(see example description).
- Navigate to the page titled "Phhysiological Effects of
Acceleration" answer the following questions:
- Describe the effect of centripetal acceleration
upon blodd flow in a person.
- In your own words, summarize the effects of acceleration
upon the average healthy person.
An 80-kg physics student is moving at 12 m/s
at the top of a loop and 20 m/s at the bottom of a loop. The
radius at the top of the loop is 6 meters and the radius at the
bottom of the loop is 14 meters. Draw free-body diagrams for the
student at the top and the bottom of the loop and determine the
acceleration, net force, and normal force for each of these
locations. (1.5 pt.)
