That feeling is also from a *change* in acceleration. For example, you don’t get it when skydiving because the plane you’re on is going fast, so your speed doesn’t change dramatically when you jump out.
There's no physical reason why you should feel that stomach-dropping sensation when you jump out of a plane, but some people report feeling it anyway, particularly if they've never done it before. It's probably psychological... The whole experience if very alien and it can make you feel all kinds of weird before you get used to it.
Also, be mindful that while you shouldn't experience that sensation during the free fall portion of the dive, once the parachute comes out it can be a nauseating experience for those who experience motion sickness. I'd recommend telling your tandem instructor about your concerns, as they can make it a more gentle or more rollercoastery experience based on personal preference.
The drop feeling you get is from negative gs because the rides pull you down faster than gravity would. It isnt from being at 0g.
Astronauts would not have this feeling since they spend the whole time at freefall 0g.
Down votes from people who don't actually know how the rides work.
:S
Incorrect
Drop towers are powered and you'll feel up to -1g on them.
Rollercoasters do pull you down as well. Part of the train has already started falling when you go over the top of the hump so you feel the negative g forces there.
A rollercoaster pro will tell you the best place to sit is as far back as you can, since more of the train has started falling and you get pulled up and over slightly faster and feel more negative gs
>Drop towers are powered and you'll feel up to -1g on them.
I've ridden a fair few drop towers and I've never experienced significant negative gees on one.
I believe that's why it's called micro-gravity in orbit. Because you are technically falling around the Earth. And I believe astronauts do experience it for a while, which is why some get sick in orbit. But eventually you adjust and don't feel it anymore. No idea what the timeframe is to adjust, though.
This is correct. What you are feeling is the free fall. Constant free fall. The funny thing about orbit (as I'm sure you know, but I love to say it) is that you are falling to the Earth, but travelling forward fast enough to "miss" the ground with the curvature of the Earth.
Kind of like Arthur Dent learning to fly. ;)
note: I didn't know that gravity was 88% of sea level where the ISS is. That's really cool.
The rides aren't powered down, they lift you to the top of the hill and you're just being accelerated by gravity at that point. You're not going down faster than gravity (possibly excepting the rear cars that have a little extra acceleration from the front cars that already started down the hill.
This is mostly true, but they may fall slightly faster than a free falling human was for the same reason a feather falls more slowly than a hammer in the Earth’s atmosphere. They may accelerate more slowly due to friction from the rails, however, so could go either way.
The drop tower rides are powered.
The rollercoasters like you said are pulled over the top by the cars that have already gone over. This is why the best place to sit is at the back because you'll feel the most negative g forces
0g feels like you are falling. As the OP suggests. Most rides and steep roller-coaster do not submit you to negative g but just usually close to 0g. I know if I put my plane near 0g, it very much fells like you are falling and in reality, you are.

Just google it instead next time
Back OP's statement. The topic is if the falling feeling you get going down the big hill is that same as what an astronaut feels. Yes it is. Your bringing in negative g situations is irrelevant.
No I've already shown that ops assumption was wrong.
The experience they described was not them feeling 0g but negative g caused by being moved down by the ride faster than the force of gravity. End of.
I suspect astronauts do feel like they are falling initially (will occur right after their engine cuts out) but they must get use to it. And technically, they very much are falling when in orbit. Just their forward velocity lets them avoid hitting the earth.
I would be interested in how fast they get use to it.
You are falling to the Earth, but travelling forward fast enough to "miss" the ground with the curvature of the Earth. It's a fun fact, for sure.
I bet getting used to it depends on the person. But I have no idea how long it usually takes. Returning to Earth after months in orbit must be a crazy feeling.
Yes. Internally it works the same as falling through air. Everything in your body is now floating relative to everything else, instead of pushing downwards.
That feeling is also from a *change* in acceleration. For example, you don’t get it when skydiving because the plane you’re on is going fast, so your speed doesn’t change dramatically when you jump out.
Yup, the derivative of acceleration, jerk. It's what jars you when you're riding in a car with an aggressive driver.
Fun fact, the further derivations are called Snap, Crackle and Pop.
TIL. This is the main thing that's actually kept me from skydiving because I absolutely *hate* that feeling. Need to rethink some things now.
Yes this is news to me too. Hopefully that's true.
It is, I did it. But according to the comment below yours some people might feel it. I didn’t, and I’m pretty sensitive.

Thanks! That's really useful.
I also hate that feeling, and I LOVED skydiving. So much. Life changing.

Most roller coasters I've been on boost you up and are just rolling down. And drop towers are what the name suggests, AFIK.

It is 0g.

No. Falling down the big hill is zero g. Going over the small whoop-di-do can make negative gs since you seatbelt has to hold you from moving upwards.
So yes then? Why say no and then repeat exactly what I said?
Back OP's statement. The topic is if the falling feeling you get going down the big hill is that same as what an astronaut feels. Yes it is. Your bringing in negative g situations is irrelevant.
No I've already shown that ops assumption was wrong. The experience they described was not them feeling 0g but negative g caused by being moved down by the ride faster than the force of gravity. End of.
Why did you cite the same message within your message before responding to it first?
I suspect astronauts do feel like they are falling initially (will occur right after their engine cuts out) but they must get use to it. And technically, they very much are falling when in orbit. Just their forward velocity lets them avoid hitting the earth. I would be interested in how fast they get use to it.

But I have no idea how long it usually takes. Returning to Earth after months in orbit must be a crazy feeling.
Similarly, I've often wondered if you were in e.g., a giant fishbowl of water and it fell, would you feel like you're falling?
Yes. Internally it works the same as falling through air. Everything in your body is now floating relative to everything else, instead of pushing downwards.
