Question : Which of the following quantities is a measure of inertia?
Option 1: Velocity
Option 2: Acceleration
Option 3: Mass
Option 4: Weight
Correct Answer: Mass
Solution : The correct option is Mass .
The inertia of an object is measured by its mass. As an object's mass increases, so does its inertia. In other words, heavier things have more inertia and are more resistant to changes in motion. It takes more force to accelerate, decelerate, or change the direction of a heavier object compared to a lighter one.
