Question
Which of the following quantities is NOT a vector in the context of angular momentum?*1 pointA . Angular momentum (L)B. Angular velocity (ω)C . Moment of inertia (I)D . Torque (τ)
Solution
The quantity that is NOT a vector in the context of angular momentum is C. Moment of Inertia (I).
Here's why:
A. Angular momentum (L) is a vector quantity. It has both magnitude and direction.
B. Angular velocity (ω) is also a vector quantity. It also has both magnitude and direction.
C. Moment of Inertia (I) is a scalar quantity. It only has magnitude and does not have a specific direction.
D. Torque (τ) is a vector quantity. It has both magnitude and direction.
So, the answer is C. Moment of Inertia (I).
