A football and a stone has same mass:I. Both have same inertia II. Both have same momentum III. Both have different inertia IV. Both have different momentum
As known, the Inertia of an object is directly proportional to the mass of the object.
$I\propto m$
Where $I\rightarrow$Inertia of the object
$m\rightarrow$ mass of the object
Because the football and the stone have the same mass, therefore the inertia of the football and the stone both have the same inertia.
Therefore, the option I is correct.
