Summary Introduction
To review:
The rationale behind the fact that when a moving person suddenly stops, there is the sensation that the person is still moving.
Introduction:
In this case, the girl came down to the first floor from the 25th floor in an express elevator. Thus, her body crossed a large distance in a downward direction very rapidly and then stopped suddenly. Even when the elevator stopped, she had a feeling that she was still in downward motion. This is a normal physiological occurrence caused by equilibrium receptors of the inner ear or vestibular apparatus.
