Nia is hanging upside down from a horizontal bar at the playground, and her long hair is not tied up. If she lets go of the bar, what happens to her hair during the fall and after she lands on her feet?

Provide a very brief response.
When Nia is hanging upside down, her hair hangs down towards the ground due to gravity. Now, when she lets go of the bar, Nia begins to fall feet-first towards the ground. While she is falling, her hair will momentarily be above her head, still under the initial influence of gravity and inertia, pointing upwards from the perspective of an onlooker. As she accelerates downward due to gravity, her hair will slowly fall back toward her head. Immediately after Nia's feet make contact with the ground, her hair would continue to move downward due to momentum, briefly becoming disordered before settling down due to gravity. Once Nia is standing, her hair will hang normally downwards towards her shoulders and back, aligned with the pull of gravity.
