Answer
Inertia is the property of an object that resists changes in its state of motion. This means that if an object is at rest, it will stay at rest unless acted upon by a force; similarly, if an object is in motion, it will keep moving at a constant velocity unless a force causes it to change.
Step 2
B. It is a measure of how difficult it is to electrically charge an object.
