Inertia is directly proportional to which quantity(s)?

Question

Quizplus · Accepted Answer

Inertia is directly proportional to mass. This can be seen in Newton's first law of motion, which states that an object at rest will remain at rest or an object in motion will remain in motion at a constant velocity unless acted upon by an external force. Objects with larger mass have more inertia and require more force to get them moving or to stop them. Force and acceleration are not directly proportional to inertia.
