Help: elevator experiment

[ericschumacher]

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 https://phyphox.org/lidar/, 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

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
