Heretic of The Seventh Circle
Unless the sphere suddenly develops seatbelts and airbags, you take falling damage. It's not the fall that hurts, it's the sudden stop at the end.
Btw, it doesn't matter if the inner wall of the sphere can hurt the person inside, either. It is literally just the sudden stop. He would take brain damage as if better punched in the head with an amount of force determined by the velocity at which he was traveling when he stopped. His body would feel like he had hit a wall, even if he doesn't physically hit anything. And this would occur even if he just ran into a reverse gravity field, and it changed his course instantly, rather than gradually.

Unless, like Iron Man's suit, the sphere dampens the inirtial force inside the sphere.
