Solution
Since mass is proportional to inertia, the greater the mass, the greater will be the inertia.
- A stone has more mass than a rubber ball of equal size. Since mass is a measure of inertia, a stone has more inertia than a rubber ball.
- A train has more inertia than a bicycle since it is much heavier.
- A five-rupee coin is heavier than a one-rupee coin. Therefore, the inertia of a five-rupees coin is more than the inertia of a one-rupee coin.
