The Crossover |

Crossovers
are used by figure skaters and speed skaters alike.
A crossover, as shown in the picture to the left, is
when a skater's foot crosses over the other. This
may seem insignificant and underwhelming, but it is
actually a very effective way to pick up speed and
maintain it while changing directions. (Hache). |

The
equation to the right illustrates the relationship
between acceleration, velocity and the radius of
turn. The tighter the turn, the more speed is
maintained. If you have ever taken a tight turn,
(in a car, bike, skate etc.) you've probably
noticed that there is a force pulling you towards
the outside of the turn, and the faster you take
the turn, the more force is acting on your body.
Thisis how centripetal forces work. On the ice
rink, skaters mmust counteract this force by
adjusting their center of graity by leaning into
the turn and decreasing the angle between the
blade of the skate and the surface of the ice. If
done correctly, the combination of the centripetal
and forward forces will result in a higher skaing
speed.
