A passenger in a moving train tosses a coin which falls behind him. This shows that the motion of the train is:
A. Along a circular track
B. Accelerated
C. Retarded
D. Uniform
Answer: Option B
Solution (By JKSSB Mock Tests)
When the coin is tossed, it moves forward with the initial velocity of the train due to inertia of motion. If the train accelerates during the time the coin is in the air, the train moves faster and travels a greater distance horizontally than the coin. Thus, the coin falls behind the passenger.
Explanation:
Newton's First Law states that a body at rest stays at rest, and a body in motion stays in uniform motion unless acted upon by an external unbalanced force. This inherent property of matter to resist any change in its state of rest or motion is called inertia, hence it is known as the Law of Inertia.
