We will show you how to measure the speed of a free fall thanks to the application for smarthphone Verner Graphical Analysis and the sensors of our phone.
​Launch the application then select a new experience and choose "Capteurs Intégrés" (see image)
​Then, simply position your phone horizontally on your hand so that your acceleration (in yellow) is equal to 10. (see image)
Then you just have to go up (get on a chair) and start recording (see picture)
​Jump and arrive at the bottom of the chair stop the recording and observe the result (see picture)
