Which of the following is a term used to describe a body's resistance to a change in motion? A. inertia B. acceleration c. gravity D. Mass

The term used to describe a body's resistance to a change in motion is A. inertia. To arrive at this answer, we can go through each option and eliminate the ones that do not fit the description.

B. Acceleration: This term refers to the rate of change of an object's velocity. It does not describe a body's resistance to a change in motion, so we can eliminate this option.

C. Gravity: This term refers to the force that attracts objects toward each other. While gravity influences motion, it does not specifically describe a body's resistance to change in motion, so we can eliminate this option as well.

D. Mass: This term refers to the amount of matter that an object posses. Although mass is related to motion, it does not explicitly describe a body's resistance to a change in motion, so we can eliminate this option.

Therefore, the correct answer is A. inertia, as it accurately describes a body's resistance to a change in motion.
