the resistance of an object to change its motion.
Inertia is the resistance of an object to change its motion.
The correct answer is: the resistance of an object to change its motion.
To understand why, let's break down the options:
1. "Responses an object's motion." This statement doesn't provide a clear definition of inertia, so it can be eliminated.
2. "A force that acts on a resting object." Inertia is not a force itself, but rather a property that describes an object's resistance to changes in motion. So this option is incorrect.
3. "The resistance of an object to change its motion." This statement correctly defines inertia. It refers to the tendency of an object to keep moving in a straight line at a constant speed or to stay at rest, unless acted upon by an external force. This option is the correct answer.
4. "A force that acts on a resting object." This statement is the same as the second option. As mentioned earlier, inertia is not a force, so this option is incorrect.
5. "A moving object's speed and direction." While inertia does affect a moving object's ability to change its speed and direction, it does not describe those characteristics themselves. Therefore, this option is not the correct definition of inertia.
In summary, inertia is the resistance of an object to change its motion.
