Because the rotational inertia is higher, it is hardest in springboard diving to perform a forward somersault in
A) the straight position (no bending at knees or waist).
B) the pike position (bending at the waist but not the knees).
C) the tuck position (bending at both the waist and knees).

Question

Quizplus · Accepted Answer

The rotational inertia of an object is related to the distribution of its mass relative to the axis of rotation. In the straight position, the diver's mass is distributed farthest from the axis of rotation, increasing the rotational inertia and making it harder to perform a forward somersault compared to the pike or tuck positions, where the mass is closer to the axis of rotation.

Because the Rotational Inertia Is Higher, It Is Hardest in Springboard
