Would it be correct to say that inertia is the reason a moving object continues in motion when no force exists?
I think that is correct. Inertia is the property that allows an object to continue moving in the same direction and at the same velocity unless acted upon by a force. I think your statement follows from that. Inertia ALSO is the property that allows an object at rest to remain at rest unless acted upon by some force.
