Answer:
Stone has more inertia.
Explanation :-
- You might have come across the concept:- inertia is a measure of mass.
- More the mass of an object,the more inertia it has.
- Stone has more mass and therefore,it has more inertia.
- Inertia is a type of resistance offered by a body to change of its state whether rest or motion.Now,Imagine yourself which will offer more resistance ,a moving stone or a moving rubber ball. Of course,it is the moving stone.Hence,in this way too we can infer that a stone has more inertia.
Additional Concept :-
- In rotational mechanics,we study a similar type of resistance called moment of inertia .The difference lies in the fact that we can calculate moment of inertia by a formula.
Moment of inertia = I = MR²
- M is the mass of the object.
- R is the perpendicular distance of the object from axis of rotation.
