प्रश्न
Give two examples to show that greater the mass, greater is the inertia of the body.
उत्तर
Examples to show that greater the mass, greater is the inertia of the body are as shown below:
(i) If you want to start a car by pushing it, you find that it takes a very large force to overcome its inertia. On the other hand, only a small force is needed to start a child's express wagon. The difference between the car and express wagon is the difference in mass. The car has a large mass, whereas the wagon has a small one.
(ii) A cricket ball is more massive than a tennis ball. The cricket ball acquires a much smaller velocity than a tennis ball when the two balls are pushed with equal force for the same time.
