Angular momentum is the product of which two factors?

Angular momentum is indeed defined as the product of rotational inertia (also known as the moment of inertia) and angular velocity. Rotational inertia reflects how mass is distributed with respect to the axis of rotation, indicating how difficult it is to change the rotational state of the object. Angular velocity measures how fast the object is rotating. When these two factors are multiplied together, they give the angular momentum, which is a crucial quantity in rotational dynamics. This relationship highlights how the momentum of a rotating object is influenced both by how mass is organized in relation to the axis of rotation and the speed of that rotation.

In contrast to this, the other choices do not accurately represent the concept of angular momentum. For instance, force and mass relate more to linear momentum rather than rotational quantities. Similarly, speed and distance do not account for the rotational aspects necessary for defining angular momentum. Mass and acceleration also pertain to linear dynamics, specifically Newton's second law, rather than addressing rotational characteristics. Thus, the choice regarding rotational inertia and angular velocity is the only one that accurately defines angular momentum in a rotational context.
