Question

Which of the following has more inertia?
(a) A rubber ball and a stone of the same size.
(b) A bicycle and a train.
(c) A five-rupee coin and a one-rupee coin.
​

Answer 1

A stone has more inertia than a rubber ball of the same size because it has more than a rubber ball of the same size. A train has more inertia than a bicycle because it has more mass than a bicycle. A 5 rupee coin has more inertia than a 1 rupee coin because it has more mass than one rupee coin.
