What is the principle of conservation of angular momentum?.
- A.The total angular momentum of a closed system remains constant if no external torques act on it.
- B.Angular momentum can be created or destroyed in a closed system.
- C.Angular momentum is always equal to the product of mass and velocity.
- D.The angular momentum of an object is always zero.
Model answer
What a good answer should say
- The total angular momentum of a closed system remains constant if no external torques act on it.
Explanation
Why this works
This statement accurately describes the conservation of angular momentum, which states that in the absence of external torques, the total angular momentum of a system remains unchanged.
