Inertia is the property of an object that resists changes in its state of motion (either rest or uniform velocity in a straight line). Inertia is directly proportional to the mass of an object. The greater the mass, the greater its inertia. Comparing the given options, a cricket ball has significantly more mass than a one-rupee coin, a molecule, or an atom. Therefore, the cricket ball has the maximum inertia among the given options.

– Inertia is the resistance of an object to changes in its state of motion.
– Inertia is a scalar quantity.
– Inertia is directly proportional to mass.

Mass is the quantitative measure of inertia. For example, it is much harder to start moving a heavy object or stop a heavy object already in motion compared to a light object, because the heavy object has more inertia.
