only objects at rest

only objects in motion

only objects whose motion is being changed

Detailed explanation-1: -All objects resist changes in their state of motion. All objects have this tendency-they have inertia.
Detailed explanation-2: -All objects have inertia, whether they are stationary or moving. Inertia explains Newton’s first law of motion, which states that an object at rest will remain at rest and an object in motion will stay in motion unless it is acted on by an unbalanced force.
Detailed explanation-3: -The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
