Explain the law of conservation of angular momentum in the case of
ballet dancer

Text Solution

Verified by Experts

Ballet dancer : Ballet dancers bring their arms closer to their body in order to increase the angular speed and decrease the moment of inertia. In order to decrease the angular speed, thus `I_1omega_1=I_2omega_2`=L=constant.
