Question

If the angular momentum is conserved in a system whose moment of

inertia is decreased. Will its rotational kinetic energy be also

conserved​

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.

Answer 2

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.
