 Help: elevator experiment ericschumacher Junior Member Posts: 4 Threads: 2 Joined: Aug 2022 Institution: Uni Koblenz Landau 08-04-2022, 11:23 AM 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 Jens Noriʇzsɔɥ Senior Member Posts: 499 Threads: 22 Joined: Apr 2020 Institution: RWTH Aachen University 08-11-2022, 05:52 PM 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? ericschumacher Junior Member Posts: 4 Threads: 2 Joined: Aug 2022 Institution: Uni Koblenz Landau 08-12-2022, 10:04 AM (This post was last modified: 08-12-2022, 10:09 AM by ericschumacher.)

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.
