Question

Quizplus · Accepted Answer

Mass is a measure of an object's resistance to acceleration, which means that the more mass an object has, the more force is required to change its motion. A and C are incorrect because mass is not related to the amount of space an object occupies or how heavy it feels. D is redundant, as the word "massive" is already an adjective describing something with a large mass.
