Two balls of the same size but of different materials, rubber and iron are kept on the smooth floor of a moving train. The brakes are applied suddenly to stop the train. Will the balls start rolling? If so, in which direction? Will they move with the same speed? Give reasons for your answer.
Can you name the three types of inertia? [5 MARKS]

Yes, both balls will start rolling due to inertia of motion. The train stops due to brakes. But the balls continue to move in the direction of the train.The two balls will not roll in the same speed.Infact, the iron ball being heavier than the rubber ball will be moving at a lower speed.
The three types of inertia are as follows:
1. Inertia of Rest
2. Inertia of Motion
3. Inertia of Direction
