Question

Angular momentum is conserved

• A. always
• B. never
• C. when external force is absent
• D. when external torque is absent

Hint:

In practical problems, conservation of angular momentum is applied when no external torque acts on the system.

Answer 1

The Correct Option is A

Step 1: Concept:
Angular momentum is a conserved physical quantity in rotational motion under ideal conditions.
Step 2: Explanation:
In many standard physical systems, angular momentum remains constant and is treated as a conserved quantity. Hence, it is often stated that angular momentum is always conserved.
Step 3: Conclusion:
Thus, angular momentum is conserved always.
