Question

if the angular momentum is conserved in a system whose moment of inertia is decreased will its ke be also conserved. explain ​

Answer 1

Answer:

if angular momentum is conserved in a system whose moment of inertia is decreased ,then rotational kinetic energy will not be conserved. ω=angular momentum. So when moment of inertia decreases, K.E of rotation increases. Thus K.E of rotation is not conserved.
