Why does a passenger jumping out of a rapidly moving bus fall forward with his face downwards -Science

Description : Why does a passenger jumping out of a rapidly moving bus fall forward with his face downwards -Science

Last Answer : When the passenger jumps out of a fast-moving bus/train, his feet will come to rest on touching the ground, whereas the upper part of his body continues to move forward, due to the inertia of motion. As a result, if he does not run forward he will fall with his face in downwards direction.
