being pulled by......? The occupant inside a rotating space habitat
of the future feels that she is being pulled by
artificial gravity against the outer wall of the
habitat (which becomes the floor).
Which statement is false?

1. centrifugal force forces her to move in a circular path
2. at every moment her tendency is to move in a straight line path
3. the floor provides the centrifugal force to keep her moving in a circular path
4. the floor intercepts her path and presses against her feet

I'm pretty sure it's number four, but i wanted an extra eye! thanks!
