Skydiving: No Sinking Stomach Feeling?

    Stomach
AI Thread Summary
Skydiving typically does not induce the sinking stomach feeling associated with roller coasters, as the experience involves a steady downward acceleration rather than rapid changes in direction. Once reaching terminal velocity, the body feels stable, minimizing any sensation of weightlessness. The discussion suggests that the gut sensation on roller coasters is due to organs accelerating differently than the body during sudden drops. Additionally, it is noted that the horizontal velocity from the airplane does not contribute to this sensation. In contrast, jumping from a mountain could potentially create that sinking feeling due to the different dynamics involved.

Hey all,

I went skydiving 2 days ago expecting to get that sinking stomach feeling that people typically experience during a roller coaster. Well, that didn't happen. It just felt like wind blowing on you. Can someone please explain?

Well I've never experienced skydiving and barely remember roller coaster rides but my guess is that on a roller coaster, you're being thrown up and down and side to side whereas when you're skydiving, you're only accelerating in one direction. I also THINK that once you hit terminal velocity, your organs won't be accelerating in any direction so it'll be relatively stable.
 
yea, i thought that organs are accelerating faster than the rest of your strapped body during a roller coaster drop. So the organs push up causing that sinking feeling. I was talking to another friend and he was saying how the horizontal velocity component (the airplane) does not cause the "gut sensation." So if you were to skydive off a mountain, you WOULD experience the sensation.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
