riddler 0 #3 June 26, 2009 At least one in every action/suspense/thriller movie these days. I have seen more skydiving in Hollywood movies this year than I've ever seen in any given year. Saw one in Star Trek (never thought I'd see a skydiving scene there) Saw one in Angels and Demons - I'm sure it had something to do with religion, but I still haven't figure out the connection there. Terminator 4 - more of a BASE jump, but pretty much a given Expecting skydiving in Harry Potter next Trapped on the surface of a sphere. XKCD Quote Share this post Link to post Share on other sites

shah269 0 #7 June 26, 2009 No forward velocity mate it would be a slow and steady fall all the way down. The reason the shuttle has a heat shield is to "burn off" all the energy it picked up going into orbit. But if are far enough and your horizontal velocity is zip......well it's all fun!Life through good thoughts, good words, and good deeds is necessary to ensure happiness and to keep chaos at bay.

If you were standing on an object in geosynchronous orbit and jumped off - nothing would happen. You'd just remain in orbit. In order to re-enter, you'd have to kill your forward velocity so you'd fall straight towards the planet. When you got there you'd have about 15,000 mph of speed to dissipate; you'd need a pretty good heat shield. Now, if you postulated a massive tower that stuck up out of the atmosphere (say, to 100,000 feet) then you could make the jump. Indeed, it would be almost identical to Kittinger's.

shah269 0 #9 June 26, 2009 True, i was assuming one would push ones self straight down. So in effect it would be like BASE jumping from a really really tall tower. But I recall doing the math at university and given modern space suits you wouldn't cook. You know what, we need to try this!

That would depend on altitude primarily. The energy you have to dissipate is M * G * H, where M is your mass, G is gravitational acceleration, and H is height above the atmosphere. I'd also point out that most modern spacesuits are not really suited for this; even the altitude protection suits that the shuttle astronauts wear (and theoretically could bail out with) are a bear to use. As you get really high, things get more complex. First, since the earth is spinning, you don't fall straight down any more; you keep some of the speed of the tower as you exit, and thus you'd start moving away from the tower after a few seconds. (This is actually true no matter how tall the tower is, but becomes more noticeable as you get higher.) Secondly, G starts decreasing, so it's not a linear equation any more.

rlucus 0 #12 June 26, 2009 Doesn't G technically increase as you fall? Mind you it doesn't really ever change very much. Now Terminal velocity decreases with altitude, as a function of air resistance. Quote Share this post Link to post Share on other sites

Yep, although there's basically no air above about 100,000 feet, so terminal velocity doesn't mean much up there. Quote Share this post Link to post Share on other sites
