3. During ice ballet, while in the outer rounds, why do the dancers outstretch their arms

and legs​

Answer 1

During ice ballet, while in the outer rounds, the dancers outstretch their arms and legs to reduce their angular speed.

• When the dancers wish to decrease their angular speed they need to increase their moment of inertia so they outstretch their arms and legs to do so.
• On the other hand if they wish to increase their angular speed then they fold their hands and legs to decrease their moment of inertia.
