- Measure the duration of a free fall using your smartphone and the acoustic stopwatch in phyphox.
The video on measuring the speed of sound can be found here:

I tried the ruler method today with my Y10s (14-15 year olds). Dropping a ball from a bench our value of g was too low but with the ball dropped from a beam just below the ceiling we got very good results. It helps them to understand that greater distance and greater time makes the reaction/response time error less significant. They also came up with the idea of one phone at the top (measures too long) and one at the bottom (measures too short) and taking the mean of these. Lots of good practical physics learning in this .
You saved my physics labs!❣️
Really a nice apk for we engineering students thanks to the development Team ..... And also thanks for the phyphix without any ads i love it ......
Buenísimo. Gracias, Física se lo agradece
Amazing!
Congratulations.
What may be the reason for the second penny taking longer to hit the ground......
I will try these with my students, hope they love it.

We have this video as the mechanics practical for free fall😂
Gracias mañana vamos a realizar este experimento en clase de Física y química
Is this free-fall or non free-fall?
Free fall. The plumb bob is sufficiently heavy that air resistance is negligible…
how can i measure the error?! please, someone help me!!!
Without considering air drag, the error comes solely from the time measuring, which is in the order of half of milissecond. Also I dis-considered the time for the sound to arrive at the phone, which is near 3 milisseconds per meter of distance....
Amazing :D
It is very useful app. Thanks for sharing.
Could you tell me which software you used to make the graph of time as a function of height?
congratulations for the initiative. the app is amazing.
I am quite sure that this graph was created with gnuplot - mostly because I used that for most things at that time. Mostly switched to Python and matplotlib since then because it is a much more familiar syntax than the gnuplot language.
@@phyphox Thank you.
太棒了!

Laboratorio I anyone?
Cosa hai dovuto fare? Mi sarebbe d'aiuto che forse lo devo fare anche io
@@NekoKyoya esperimento di caduta libera, ricavare g dal tempo misurato in questo esperimento
@@lorenzosimeone354 proprio non puoi ? Ahaha
@@NekoKyoya cosa, non posso
@@lorenzosimeone354 va bene scusa, non pensavo non potessi
Vous aussi c chiant ou c que moi ?
