2. When a passenger jumps out of a Train in a railway platform he starts running with the train first and then slows down What is the reason ? A Because he was under motion when he was in the train. But when his foot touches the ground his body which is under Inertia of Motion Cannot change to Inertia of Rest. B Because he was under rest when he was in the train. But when his foot touches the ground his body which is under Inertia of Rest Cannot change to Inertia of Motion.

3. No. You are wrong. The Body when at train it is under Inertia of Motion with the moving train. But the ground where his foot touches is at Inertia of Rest. So his body was not able to change suddenly its Inertia of Motion to Inertia of Rest. Go Back and Try Again

4. You are correct. Proceed Further

5. When a cloth containing dust waved suddenly the dust in it are thrown out. This is a simple way we commonly use to get rid of dust from our towel or blanket. How this becomes possible? A The dust is forced out because of the force which we are giving while waving it. B The dust is forced out because the dust is in Inertia of Rest. When the cloth is waved suddenly with a force, the dust cannot come to motion as it is unable to do so. This is the reason behind it.

6. You are Wrong. Not only the force that matters. Think about the Inertia. Go Back and Try Again

7. You are correct. Proceed Further
