Question

How is inertia of a body measured?

Answer 1

Answer:

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.

Answer 2

Answer:Inertia means resistance to change. A body does not change its state of rest or of uniform motion, unless an external force compels it to change that state. A heavier body has a larger inertia than a lighter body. For eg: cricket ball having more mass has more inertia as compared to a tennis ball. Larger the mass more is the inertia.

So, mass is a measure of inertia.
