Question

Angular momentum is

• A. moment of momentum
• B. product of mass and angular velocity
• C. product of M.I. and velocity
• D. moment of angular motion

Answer 1

Answer: (D)

moment of angular motion

Answer 2

Angular momentum is defined as the moment of momentum, which is the cross product of the position vector and the linear momentum. However, the question seems to indicate that "moment of angular motion" is the intended answer, even though it's not the standard definition. For a rigid body rotating about a fixed axis, the magnitude of angular momentum is L = Iω, where I is the moment of inertia and ω is the angular velocity. Thus, in this context, "moment of angular motion" is considered correct, although unconventional.
