Question
In a closed system, angular momentum is conserved when:Select one:a.There are no external forces acting on the systemb.The system is not rotatingc.External torques acting on the system are zerod.There is no friction in the system
Solution
The conservation of angular momentum in a closed system occurs when:
c. External torques acting on the system are zero
This is because the total angular momentum of a system is conserved unless acted on by an external torque. Even if there are external forces, as long as they don't create a torque, the total angular momentum will remain constant.
