Do all bodies have the same inertia? Explain it with an example.

All bodies do not resist a change in their state of motion to the same extent. Some resist more than others. For example, if we give a hard kick to a football, it flies off. But if we kick a stone of same size with an equal force, it may not move at all, rather we injure ourselves. This is because, the inertia of the stone is more than that of the football. Hence more massive an object, greater will be its inertia.
