प्रश्न
Why does a ball thrown vertically upwards in a moving train , come back to the thrower's hand ?
उत्तर
The reason is that when the ball is thrown, the ball is in motion along with the person and train. Due to the inertia of motion, during the time the ball remains in air, the person and ball move ahead by the same distance. This makes the ball fall back into the thrower's hand.
