There is a scene in the movie where we can see the lead actor running/jogging in the space shuttle bound to Jupiter and there is a scene in the beginning where an air hostess uses velcro kind of shoes and then spins 360 degrees and then walks into another room. Why does she needs a magnetic/velcro shoes and the person jogging doesnt? Is it related to speed?

The Discovery One (the space ship bound to Jupiter) has a centrifuge that provides artificial gravity through rotation in a small section of the ship.

"Is it related to speed?" On a side note. If the Hostess had been able to run fast enough around the inner ring, she would have created her own centripetal effect. If the Jogger goes in the direction the 'big tube' is spinning, he'd feel heavier, opposite, lighter.. – Andrew Thompson Dec 26 '13 at 14:18
@Andrew: If you run fast enough, you can make your own centrifuge. – Keith Thompson Dec 26 '13 at 16:27
