which of the following has more inertia, explain with reason. 1. a rubber ball and stone of same size? 2. a bicycle and a train? 3. a five rupee coin and a 1 rupee coin?
Answers
Answer:
1.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.
2.Mass of a train is more than the mass of a bicycle. Hence, inertia of the train is greater than that of the bicycle.
3.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.
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.
