Technology and Skiing |
- Find times for a Canadian skier at the Lauberhorn race.
Calculate his average speed. Express this speed as a percentage
of the terminal speed for a human falling through air: about
55 m/s for a spread-eagle position.
- Research a new development in ski boots, bindings, clothing,
or helmets, and report on the development to your class in an
oral presentation.
The
Federation Internationale de Ski runs World Cup alpine races
such as the Lauberhorn downhill in Wengen, Switzerland. To find
results, use the search engine in its calendar.

Displacement from Velocity-Time Graphs |
If you are having difficulties solving motion
problems in one dimension, you are not alone. Even physicists
find it challenging. There are still some unsolved problems for
one-dimensional acceleration. Find out, in general, what types
of problems remain unsolved. Try to offer some solutions!
The
Physics Classroom: One Dimensional Kinematics, Tom Henderson,
Glenbrook South High School.Illinois, USA, gives a wide range
of information on this science.

Acceleration Due to Gravity |
NASA has conducted and continues to conduct
many experiments in "free fall". What are some of the purposes
of these experiments? How are they done? What information has
been obtained? What are some other questions left to be answered?
NASA
Microgravity Science Laboratory has very good links to a number
of microgravity experiments.
Free-Fall
and Microgravity, NASA, contains more information on microgravity
and experiments.
Life
and Microgravity, NASA, gives a good overview on what NASA is
doing in this area.
Microgravity
Science, NASA Space Station, contains information on experiments
performed here.

Gravitational Acceleration Near Earth |
The Geodetic Survey Division of the Department
of Natural Resources Canada has measured the acceleration due
to gravity at thousands of locations across the country. Why have
they done this? Who uses this information? How precise are their
measurements?
The
National Gravity Program, Geodetic Survey of Canada is a very
comprehensive site.
