प्रश्न
Explain why, it is dangerous to jump out of a moving bus.
उत्तर
It is dangerous to jump out of a moving bus because the person who jumps is moving with the same speed as that of the bus and would tend to remain in motion (due to inertia) even after falling to the ground; thus, he may get hurt due to the resistance of the stationary ground.
