Conservation of Angular Momentum

In physics, angular momentum ($L$) is conserved when an athlete is in the air. The formula is $L = I \times \omega$, where $I$ is the Moment of Inertia (how spread out your mass is) and $\omega$ is your rotational speed.

  • Layout (Straight): Your mass is spread far from your center. Your moment of inertia ($I$) is high, so your spin rate ($\omega$) is slow.
  • Pike (Bent at hips): Your mass is closer to the center. Inertia drops, so your spin rate increases automatically!
  • Tuck (Knees to chest): You are curled into a tiny ball. Your inertia is extremely low, causing you to spin incredibly fast to conserve momentum.
