A) its color.
B) how fast it is spinning.
C) how its mass is distributed about the spin axis.
D) the amount of torque applied to it.
E) none of these.

Question

Quizplus · Accepted Answer

The rotational inertia of an object depends on how its mass is distributed about the spin axis. Factors that affect this distribution include the shape, size, and density of the object. The speed at which it is spinning and the amount of torque applied to it do not directly affect its rotational inertia, although they can affect its angular acceleration. The object's color is irrelevant to its rotational inertia.
