E)linear acceleration about the axis.

Question

Quizplus · Accepted Answer

The rotational inertia (also known as moment of inertia) of an object about an axis depends on the mass distribution of the object with respect to that axis. It is a measure of the resistance of an object to rotational motion around that axis. The other choices are not directly related to rotational inertia; angular velocity and acceleration are affected by the moment of inertia, torque is the product of moment of inertia and angular acceleration, and linear acceleration has no effect on rotational inertia.
