Help: elevator experiment
Good morning
I would like to change the elevator experiment a bit: The acceleration should not be determined via the acceleration sensor, but as a differential calculation of the speed. The speed was determined as a differential calculation from the height, it should stay that way.
Would it be possible if someone could adapt this experiment to do so? Unfortunately I couldn't do it with the editor.

Thank you very much and have a nice day.
Best wishes, Eric
Technically, it is rather straightforward and, in such cases, it is typically easier to resort to a simple text editor, cut-and-paste a bit.

Practically, the results would be quite likely … unpleasant. We have done that on some other occasions and with raw data the double numerical derivation leads to an (almost) meaningless acceleration graph. We solved it with a locally weighted scatterplot smoothing, see, for instance, however, the rate of the barometer might by too low…

Where would you like to utilise the adapted experiment?

Hi Jens, thanks for your answer.

i'm a student to become a teacher. I am currently writing my master's thesis on the possible applications of Phyphox in mathematics lessons, at extracurricular learning lecations. Therefor, it would not be a problem for the master's thesis if the double numerical differentation values are not perfect. I an also say that in the thesis Smile

ich would like to use the experiement during a 20 meter free fall, similar to bungee jump.

LG Eric

edit: unfortunately I can't get the experiement programmed or changed by coping & pasting
Best drop me an e-mail: you can (also) reach me by the address given on the phyphox homepage…
