Which of these would have the LEAST amount of inertia? A. a car B. a building C. a gold brick D. a moving car

Answer: (c) a gold brick would have the least amount of inertia.

The inertia of an object refers to its ability to continue in its present state of rest or uniform motion until any external force act of the body to change its state of motion.

The inertia of a body increases with its mass. For this reason, a body with more mass and high inertia needs larger force to change its state of motion or rest. Among the given objects, the mass of a gold brick is the least. For this reason, it would have the least amount of inertia and least amount of force is required to change its state of motion or rest.
