Final answer:
The correct statement about inertia is that the greater the mass of an object, the more it will resist motion due to its higher inertia.
Step-by-step explanation:
Inertia is an object’s resistance to changes in its state of motion. The resistance to motion of an object increases with its mass, meaning heavier objects have more inertia and require more force to change their motion than lighter ones. The correct statement from the options provided is: The greater the mass of an object, the greater it will resist motion. This means an object with more mass will exhibit greater inertia and hence will be harder to start moving or stop if it's already in motion. Conversely, an object with less mass has less inertia and is more easily affected by forces. The strength of this resistance is directly proportional to the mass of the object, which is a measure of the amount of matter within it. Therefore, answer A is correct: The greater the mass of an object, the greater it will resist motion.
