Angular momentum is conserved when:

A.Torque is constant

B.Angular velocity is constant

C.The object is at rest

D.Net external torque is zero

Explanation

Core Concept

Angular momentum (L = Iω) is conserved when the net external torque acting on a system is zero, analogous to how linear momentum is conserved when net external force is zero.

Correct Answer

DNet external torque is zero
