Question

Which of the following has more inertia:

(a) a rubber ball or a stone of the same size?

(b) a bicycle or a train?

(c) a five-rupee coin or a one-rupee coin?

Answer 1

(a) A stone of the size of a rubber ball has more mass than the rubber ball. So, the stone of the size of the rubber ball has more inertia than the rubber ball.

(b) A train has more mass than a bicycle. So, the train has more inertia than the bicycle.

(c) A five-rupee coin has more mass than a one-rupee coin. So, the five-rupee coin has more inertia than the one-rupee coin.
