thank you for the answers

how do "zero g" planes work? As the title says, I'm curious about how Zero G planes work. They can't get into orbit , because there's no way they're engines could provide thrust for such speed, and they don't really leave the atmosphere. I've read that they way it's done is by simulating sort...

Thank you guys, it all makes sense to me now. It's always good to have someone confirm your thoughts :D

Question that was always bugging me. Why doesn't a helicopter which could theoretically hover on the spot for hours doesn't end up in another part of the world. Since it's off from the ground doesn't it lose the velocity of Earth's rotation? What keeps it in the same place/at same velocity...

My third question is.. if orbiting is just a continuous free fall without any resistance , wouldn't you feel the same weightlessness when skydiving out of the plane? if yes, the how are you able to distinguish up and down while skydiving and not in space where every way you turn you feel the same?

so it can orbit?

noo, i said imagine there's no atmosphere, like on the moon.

My 2nd question is.. Does orbit depend on distance from the planet? Say, if i would have had superman powers and could throw a rock from just 6 feet above the Earth with enough speed so that the rock can "fall" into orbit, considering there's no atmosphere to create drag, could the rock orbit...

Hello, I'm new here and am very glad I found these forums, I've been seeking answers for some questions that have been bothering me for some time. Ok, first of all I want to ask about orbits. I know what an orbit is ( a very fast object virtually falling endlessly , never touching the ground...
