Science Question on Newton’s First Law Of Motion
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-rupees coin and a one-rupee coin?
Answer
Inertia of an object is the measurement of its mass.
(a) A stone of same size as that of rubber ball will have a greater mass because the stone will have more inertia.
(b) A train has much greater mass than that of a bicycle, so the train will have more inertia.
(c) A five-rupee coin has more mass than a one-rupee coin, so five-rupee coin will have greater inertia.
