What weightlessness feels like on Zero-G planes

    The zero g plane, also known as a parabolic flight, or the vomit comet, flies in parabolic trajectories to give a brief experience of weightlessness. This flight, operated by Novespace in Bordeaux, France, offered 14 weightless parabolas, 2 parabolas with a simulation of moon gravity, and one with Mars gravity. I brought some demos to try out on the vomit comet, with little to no success. But who can ever prepare for these weightless things? Watch to find out whether I threw up!

    If the rate of acceleration does not decrease with increase in speed then a high gravitational force should increase it beyond the speed of light. where does the acceleration fade or stop.

    That is so neat. I wonder if the tumblers on a traditional lock would be easier to manipulate in zero g or would the springs still press down with the same force and it be no different..... 🤔

    4:00 I am so disappointed. *YOU* should know better. A parabola is a curved line an object would follow if it was ballistic. The shape of this curve depends only on the horizontal velocity of the object. Basically, it is an orbit.
    At the speed that plane goes that orbit intersects the ground, but if the Earth were tiny, but still hat the same mass, you would just go in a big circle.

    That 1.8 g pull up/pull out period is about a third of the g force you experience on the world's tallest rollercoaster (which at the time of this comment, is Kingda Ka at Six Flags Great Adventure). The hydraulic launch system accelerates trains at 16.3 (m/s)/s (1.7 forward g's) the maximum vertical g force is somewhere around 6 g's depending on the launch speed ( some launches are faster than others, but 128 MPH on average).

    I have a really hard time believing anything an Apple user says. They probably think Volkswagon is the most reliable car maker in the world, too.

    • Tim
      Tim Month ago

      @Dan The-Man I can only talk from my experience but I work at a company that wants us to have a work phone and a laptop so we all get iPhone's and Macbooks by default. I was sceptical at first but they are great products when you get to know them. Most of us also have the option to lease a car, the Volkswagen Golf and Polo are popular choices and I don't see anyone having trouble with it. They are great cars to drive.

    • Dan The-Man

      @Tim Every Volkswagon owner I've ever known is constantly fixing everything, and Apple is great at engineering serious defects and making the consumers pay through the nose to fix it.

    that weightlessness doesn't seem as smooth as you see on the international space station. it looks like there is always some sideway movement that isn't suppose to be there.

    I had to look up what they injected you with for the flight because it sounded like it gave you the same side effects as the medicine I take for my IBS! Turns out I was right! They are both anticholinergics and antispasmodics!

    When I was a pilot, I flew a couple zero-G parabolas. You can get maybe 10 seconds of zero-G in a small plane. My sister was with me and she had a pencil in her hand that I used as a G meter.
    Obviously, it was nothing like these kind of flights, but it was pretty cool anyway!

    I’m revisiting to pretend again I’m in this flight for a couple of parabolic pull-ups and pull-outs. Ergo, felt weightless for a couple of seconds...
    The third time’s the charm !
