In a four revolution jump, the skater rotates 360 degrees x four which equals 1440
degrees combined in the air. This counts as the displacement of the skater.
The average radius of a typical skater performing quad jumps is around 3.75. When the
math is completed, the answer for the angular rotation is
1440 degrees / 3.75 in = 384 degrees/in
This represents the angular rotation that the average skater must get to when performing
quad jumps.
The time for a quad is 0.75 second which means that Δt is going to equal 0.75.
w = (384 degrees/in) / (0.75 s)
= 512 degrees/in per second
This number demonstrates how quick advanced figure skaters must rotate while in the air to land
a successful quad jump. The average human would not be able to withstand this amount of body
pressure without extensive training.
