ABy its weight, which is the same everywhere
BBy its volume, which changes with location
CBy its mass, which is the same everywhere
DBy its density, which changes with location
Answer & Solution
Correct answer: C. By its mass, which is the same everywhere
1. The inertia of an object is measured by its mass.
2. Mass is a measure of the amount of matter in something.
3. Unlike weight, mass does not vary with location.
4. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.
5. Weight does change with location, so it cannot be the measure of inertia.
