Plz give me brief note on ballet dancer

Answer 1

$\huge\star\mathfrak\red{{Answer:-}}$

Ballet dancers:

During ice ballet, the

dancers have to undertake rounds of smaller

and larger radii. The dancers come together

while taking the rounds of smaller radius (near

the centre). In this case, the moment of inertia

of their system becomes minimum and the

frequency increases, to make it thrilling. While

outer rounds, the dancers outstretch their legs

and arms. This increases their moment of

inertia that reduces the angular speed and

hence the linear speed. This is essential to

prevent slipping
