Hello!
I did an experiment in science class today where we held a piece of paper in our hands and blew on it from the front. Unfortunately, I didn't understand it at all… 🙁
Our teacher showed us the picture below.
Can you help me? It would be soooo important!
Thank you and see you soon!

Loading...Good morning, My question is already in the title. I've already researched this topic and found two formulas. Using t = square root of (2*s) / a, you can calculate the time for a given distance with a given acceleration. You can also calculate the time with a given velocity using t = s/v. But…
It would be very helpful if someone could explain to me which formula I should use for this and why. Thanks in advance.
Energy supply and AI are currently on everyone's lips. The movie "Terminator 2" mentions a power cell that supplies the cyborg with energy for 120 years. What kind of energy could this be? https://www.youtube.com/watch?v=LcDe5xWejas
Could someone please explain 6b to me? I've already done 6a. Thanks in advance.
The total pressure consisting of dynamic and static pressure remains constant. When the fluid flows faster, the static pressure drops. When it flows more slowly, the static pressure rises. The pressure is therefore greater below the sheet and the sheet rises or floats
This is a good attempt to aerodynamics to illustrate the uplift on aircraft wings.
The effective negative pressure on the upper side of a supporting surface contributes most strongly to the lift, whereas the lower dynamic pressure is far lower.
Planes “hang” in the air. Therefore, it is also fatal if trim parts are released on the upper side of the support surface.
There is also one great counter-test:
Wool a sheet of thick paper or cardboard, and place it on the table as a cardboard tunnel. Then blow into the cavity under the leaf and try to release it from the table top. The opposite happens: the sheet “sucks” firmly.
I have a physically not entirely correct explanation for you, but it is very clear and at least not quite wrong.
That’s grossly wrong now, but maybe there’s an idea why it works.
p.s. To all those who know the physically correct words and can count on the equations of Bernoulli, it will be for you if you can not call a trivial statement suitable for the physically unrelated reader, because that does not help the questioner at all.
