$\huge \bigstar{ \underline{ \underline \bold \purple{Question:}}}$
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) Mass of a stone is more than the mass of a rubber ball for the same size. Hence, inertia of the stone is greater than that of a rubber ball.

(b) Mass of a train is more than the mass of a bicycle. Hence, inertia of the train is greater than that of the bicycle.

(c) Mass of a five rupee coin is more than that of a one-rupee coin. Hence, inertia of the five rupee coin is greater than that of the one-rupee coin.
