Concept explainers
Momentum is conserved when there is no net external force. When is
The condition when the angular momentum of a system is conserved.
Answer to Problem 12A
In case of no external torque
Explanation of Solution
Introduction:
When there is no net external force on the considered system, then the momentum of the system remains conserved.
Similarly, when no external torque is exerted on a considered rotational system, then the angular momentum of the system remains conserved.
Conclusion:
Hence, the angular momentum remains same conserved in case of no external torque.
