* Inertia is the fundamental property of matter that resists changes in its state of motion. This means an object at rest wants to stay at rest, and an object in motion wants to stay in motion at the same speed and direction.

Let's look at why the other options are incorrect:

* Displacement is the change in position of an object.

* Momentum is a measure of an object's mass in motion (mass x velocity).

* Acceleration is the rate of change of velocity.
