Background
The Luge Competition at the Winter Olympics consists of each team having a
sled or "luge" and one rider that operates the luge. The runner begins the
race by sitting in the sled and using bars on the sides of the track to
propel himself or herself onto the track, moving as fast as possible. The
slider then lays back on the sled with his or her toes pointed towards each
other. The slider negotiates the curves by leaning to either one side or the
other.
The speed of the luge run varies from track to track, person to person, and
even day to day. Factors like temperature, wind speed, weight of the slider
and steepness of the track are all contributors. These lessons will explore
some of the forces that act upon a luge and rider, and the science behind it.
- Activity One:
-
This activity concentrates on the basic force of motion, gravity. It
teaches how gravity has an influence on speed and time of the luge run.
- Activity Two:
-
This activity focuses on friction and how it affects the movement of the
luge.
