Question 1 (b)
Which of the following has more inertia:
(b) a bicycle and a train?

Answer 1

Inertia is the measure of the mass of the body. The greater is the mass of the body; the greater is its inertia and vice-versa.
(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.
