Hello,
I'm currently working on a lesson for my computer science class with my students to explore all the sensors available in a phone.
I'm trying to understand how the acceleration values from my graph.
My experiment is to drop my phone from 1.5m up and to check the values of the acceleration.
In attachment you cans see I'm having two high positive values that are matching the two falls from different heights (second one is higher).
My question is why is my phoning detecting a positive acceleration of >60m/s² as the phone shouldn't really accelerate more than the gravity (9.81m/s²).
From what I concluded, the high value corresponds to when my phone hits the ground (blanket), but why does the phone captures an acceleration.
Sorry if this is more of a general science question than about the phone, but I'm having trouble understanding the results here.
Thank you for your help!
