Question

3 which has more inertia, a kilogram of feathers or a kilogram of iron? a the law of inertia does not apply in this case b the iron because they are heavier c the feathers because they are lighter d they have the same inertia because the masses are equal

Explanation:

Inertia is a property of matter that depends on mass. The greater the mass of an object, the greater its inertia. Here, both the feathers and the iron have a mass of 1 kilogram. Since their masses are equal, their inertias are also equal.

Answer:

D. They have the same inertia because the masses are equal
