प्रश्न
Two similar vehicles are moving with the same velocity on the road, such that one of thus is loaded and the other one is empty which of the two vehicles will require larger force to stop?

उत्तर
A large force is required to stop the loaded vehicle. It is because the loaded vehicle has greater momentum than the empty vehicle as the mass of the loaded vehicle is more than that of the empty one. So, it requires more force to stop.
