Q: Answer-As soon as a train starts moving, the head of a person sitting in it transcends backwards. The cause...

According to the law of inertia of stability, if an object is at rest or moves with uniform velocity in a straight line, then its state of rest or uniform motion changes only when an external force is applied to it. When the train starts moving, the person sitting in it is initially at rest and appears to move backwards with respect to the train. This phenomenon is explained by inertia of stability.
