Question

write about the Ballet dancers in physics ​

Answer 1

$\huge\bf{\underline{\underline{Answer : -}}}$

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.

Answer 2

Explanation:

Physics can help a dancer understand, he would explain, why bringing the legs together will let her complete a grand jeté en tournant.
