BRubber ball is faster than iron ball
BRubber ball is faster than iron ball(a) Inertia is the name for the tendency of an object in motion to remain in motion, or an object at rest to remain at rest, unless acted upon by a force. This concept was quantified in Newton's First Law of Motion. For example when a car is abruptly accelerated, drivers and passengers may feel as though their bodies are moving backward. In reality, inertia is making the body want to stay in place as the car moves forward.

But the balls continue to move in the direction of the train. But the balls will not roll with the same speed. Iron ball will move slower than the rubber ball because it is heavier in weight.
