AS REPORTEDno primary record reached; this is what the reporting says

Is it true that inertia is an object's resistance to acceleration, whereas momentum is the product of mass and velocity?

Yes. Standard physical definitions confirm that inertia describes an object's resistance to changes in motion or acceleration, while momentum is defined as the product of mass and velocity.
