The property of objects that resists change in motion is called inertia.

Here's a breakdown:

* Inertia is the tendency of an object to resist 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.

* The more massive an object is, the greater its inertia, meaning it takes more force to change its motion.
