# racers airtime?

Air time means that your travel vector is away from the mountain therefore away from your destination, that being down the hill.  In light of that, yes.

Yes, if by "airtime" you mean time spent with the skis out of contact with the snow.

If, by "airtime," you mean something like exposure on TV networks, they don't avoid it ... it just works out that way.

Snow is faster than air...

Also messes your line if you fly too long... Your not in control in the air.

Forces on the skier in the air:

1)  Gravity (pointing down)

2)  Air resistance (pointing backwards/opposite to skier's motion)

Net force = down and backwards

Forces on the skier on the ground:

1)  Gravity (pointing down)

2)  Air resistance (pointing backwards/opposite to skier's motion)

3)  The ground (pointing perpendicular to the surface of the ground - typically up and forward)

4)  Resistance between the skis and the snow (pointing backwards/opposite to skier's motion)

Net force = down and more forward than the skier in the air, especially since #3 is much smaller than #4.

I'd draw a little force vector diagram, but I don't feel like it...  :)

Basically, the idea is that in the case of the skier on the ground, there is more forward force/acceleration.  The contact with the slanted surface of the snow converts some of the downward gravitational force into forward force.  Forward force = forward acceleration = getting to the finish line sooner.
