Question

Moment of inertia describes Select one: a. How the mass of an extended object is distributed about a rotation axis. b. How a force can rotate an object. c. The average position of the mass in an extended object. d. The tendency of an object to move in a circular path. e. The tendency of an object to move in a straight line.

Answer 1

Answer: a. How the mass of an extended object is distributed about a rotation axis

Explanation: Moment of inertia is defined as the measure of the rotational inertia of a solid object, it is a quantity that defines the torque needed to reach a desired angular acceleration around a given rotation axis, and it depends mainly on the mass distribution of the object, so the correct answer is: "how the mass of an extended object is distributed about a rotation axis"
