Question

A person getting out of a moving bus falls in the forward direction. Why?

Answer 1

If someone tries to get out of a moving bus then the momentum makes the person move forward. A person might fall in the forward direction due to moment of inertia when the speed is fast. This can be explained by the Newtons's law of inertia. The direction and speed of the person is the same as that of bus. As the person gets out of the moving bus the momentum is reduced to zero.
