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.

A

moment of inertia

B

angular momentum

C

kinetic energy

D

angular velocity

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
Angular momentum remain conserved & moment of inertia increases, from
`L = I omega, omega` will decrease and
`KE_("Rotational") = (L^(2))/(2 I), so, KE_("Rotational")` will increase.
