Question

Explain why when a corridor train suddenly starts, the sliding door of some compartment may open?

Answer 1

Answer:

This is due to inertia of rest

Explanation:

According to Newton's first law of motion, a body at rest tends to be at rest unless an external force is applied on it to change the state of rest.As the frame of the door is in contact with the floor of the train the frame moves along with the train but the sliding door tends to be at rest due to inertia of rest.Thus the frame moves ahead with the train and the door slides in the direction opposite to the motion of the train.
