A spinning ballet dancer changes the shape of her body by spreading her arms.

A man spinning in free space changes the shape of his body, eg. By spreading his arms or curling up. By doing this, he can change his.

Can balanced forces change the shape and size of a body?

The reason for the change in shape of a regular body is

A man spinning in free space can change the moment of inrtia of his body (I) by charging its shape. In this process,

A dancer is standing on a stool rotating about the vertical axis passing through its centre. She pulls her arms towards the body reducing her moment of inertia by a factor of n. The new angular speed of turn table is proportional to

A dancer on ice spins faster when she folds her arms due to

A ballet dancer, dancing on a smooth floor is spinning about a vertical axis with her arms folded with angular velocity of 20 rad//s . When the stretches her arms fully, the spinning speed decrease in 10 rad//s . If I is the initial moment of inertia of the dancer, the new moment of inertia is.
