what happens with non-perfectly friction-free gyros, How is friction make the gyros fall?

my teacher explains that the reason for the falling of gyroscope is the effect of Coriolis force Thanks again for everyone's answers!

I even don't know german :rolleyes: I think paying attention to the rotation of the Earth is an interesting idea. I've not noticed that before. Thank you a lot

I think that when this spin components get smaller, the precession angular speed Ω=wr/Iω become larger, but not related to the falling of wheel (with w: weight of the wheel, r: distance of wheel from the pivot, I: angular momentum, ω: angular speed of the wheel)

seem everyone is off-topic. What about my question :cry::cry::cry:

I'm not sure if adding a link is okay. If not, please remind me. at the end of this video, the wheel is falling, though it continuously spins. I want a formula showing how to friction affect the gyroscope

why when the gyroscope work for a short time, it will fall down slowly. I know that the system loses the energy by work done by friction between the wheel and its axis, but I don't understand how this makes the gyro drops. I think the friction makes the wheel spin slowly, and precession...
