Which of the following has more interia:...

Which of the following has more interia: (a) a rubber ball and a stone of the same size? (b) a bicycle and a train (c) a five-repees coin and a one-rupee coin?

Text Solution

Verified by Experts

(a) A stone of the same size as rubber ball has more mass. As mass is a measure of inertia, therefore, stone has more inertia than a rubber ball. (b) A trin has greater inertia than a bicycle, because trin is much heavier than a bicycle. (c ) A five-rupees coin is heavier than a one-rupee coin. Therefore, inertia, of five-ruppees coin is more than the inertia of one-rupee coin.
