How does an object’s mass affect its inertia?

Question

Increasing an object’s mass will increase its inertia.

Changing an object’s mass has no effect on its inertia.

Decreasing an object’s mass will increase its inertia.

Increasing an object’s mass will decrease its inertia.

Answer 1

The correct statement is: Increasing an object’s mass will increase its inertia.

Inertia is the property of an object that resists changes to its state of motion. It is directly related to mass; therefore, a more massive object has greater inertia, meaning it requires more force to change its velocity (either to accelerate it or to decelerate it) compared to an object with less mass.
