# 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 :

(a) Since, we know Inertia depends on the mass of an object hence, in the case of a rubber ball and a stone of the same size , stone will be having a greater Inertia.

(b) As we know that Inertia is the measure of mass of an object hence, in the case of a bicycle and a train, since, train has a larger mass. Hence, it will have a greater Inertia too.

(c) Since, Inertia is directly proportional to the mass of an object hence, in the case of a five-rupee coin and a one-rupee coin, a five-rupee coin has more inertia (than a one-rupee coin) because it has more mass than a one rupee coin.
