Detailed explanation-1: -Inertia is the property of an object by which it opposes any change in its state. It depends upon the mass of body. More the mass of body, more is the inertia. Hence quantitative measure of inertia is mass of the body.

Detailed explanation-2: -There are two numerical measures of the inertia of a body: its mass, which governs its resistance to the action of a force, and its moment of inertia about a specified axis, which measures its resistance to the action of a torque about the same axis. See Newton’s laws of motion.

Detailed explanation-3: -Mass is the quantity or measure of inertia in an object. The more mass found in an object, the more inertia it contains and therefore the greater its tendency to resist change.

Detailed explanation-4: -Perhaps Galileo’s greatest contribution to physics was his formulation of the concept of inertia: an object in a state of motion possesses an “inertia” that causes it to remain in that state of motion unless an external force acts on it. Most objects in a state of motion do NOT remain in that state of motion.

Detailed explanation-5: -mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force.
