Ski
jumping
The sport of
ski jumping incorporates reducing the amount of
air resistance on the skier’s body as he jumps
down an inclined slope in an effort in increase
the distance of the jump. Again, the crouch
position accomplishes the reduction needed.
An additional way to maximize the jump distance is
to minimize air resistance and maximize lift
during the time the skier is airborne.
Leaning forward and making a V-shape with the skis
increases the total area, creating drag as he goes
thru the air. This increases the amount of
lift produced by air passing by his body as he
descends; in turn, slowing his descent and
allowing an increase in the distance of his jump.
