That's not quite right. The property of inertia actually states that an object at rest will tend to stay at rest, and an object in motion will tend to stay in motion at a constant velocity.

Here's a more detailed explanation:

* Inertia is the tendency of an object to resist changes in its motion. This means that an object at rest wants to stay at rest, and an object in motion wants to keep moving at the same speed and in the same direction.

* To get an object to move, a force is required. This force overcomes the object's inertia.

* To change the velocity of an object (speed or direction) a force is also required. Again, this force is needed to overcome the object's inertia.

Think of it this way:

* A book on a table will stay there unless you push it. The book has inertia.

* A car moving down the road will keep moving at the same speed unless you hit the brakes. The car also has inertia.

So, while inertia does play a role in the initiation of motion, it's not the sole factor. A force is required to overcome the object's inertia and get it moving.
