Given a scientific passage and an answer, generate a question for the given answer.

Passage: The angular momentum of a spinning object can be found in two equivalent ways. Just like linear momentum, one way, shown in the first equation, is to multiply the moment of inertia, the rotational analog of mass, with the angular velocity. The other way is simply multiplying the linear momentum by the radius, as shown in the second equation. Answer: angular momentum
Multiplying the linear momentum of a spinning object by the radius calculates what?
