A passenger in a moving train tosses a coin which falls behind him why?
A. Because motion of train is accelerated
B. Because the motion of the train is at rest.
C. Because motion of train is deflated
D. None.

Hint: To answer this question, we first need to understand what is inertia. The resistance of any physical object to any change in velocity is known as inertia. Changes in the object's speed or direction of motion are included. The tendency of objects to continue travelling in a straight line at a steady speed when no forces occur on them is one example of this feature.

Complete step-by-step solution:
Inertia of motion - The following is an explanation of motion inertia: Unless an external balancing force acts on it to modify its state of motion, a body in motion will tend to stay in exactly the same state of motion (with the same speed and direction). The following are some common examples of motion inertia that we see in our daily lives:
When riding a motorcycle as a passenger, the driver suddenly applies the brakes, causing the passenger to be pushed forward. This is because the passenger is moving forward, and the inertia of motion always resists a change in motion.
When a bus passenger tries to jump off the moving bus, the inertia of motion leads him or her to fall down or lose his or her equilibrium temporarily. This is due to the fact that when a passenger jumps, the body's inertia of motion tends to fight the change in condition.
We conclude, the person seated in the train goes forward as the train speeds up or accelerates, but the position of the coin remains the same. As a result, the coin falls behind him.
So, the final answer is option (A) i.e. Because the motion of the train is accelerated.

Note: Inertia is caused by some form of local field, perhaps not our A field. When you press down on an object, a gravitational disturbance is created that travels into the past or the future. The disturbance causes distant matter in the cosmos to wriggle in the past or future.
