Question

Explain why when a train suddenly moves forward, the passenger standing in the compartment tends to fall backwards.

ICSE Class 9 Physics Chapter Newton's Law of Motion

Answer 1

The passengers fall backwards because of law of inertia. ( first law of motion)

Law of inertia states that an object remains in a state of rest or of uniform motion in a straight path unless forced to change that state by an applied force.

so, the passengers are in rest when train moves suddenly then the state of rest break by applied force.

I hope it helps :)
