What teachers want to learn from this workshop

My own learning

data from one fo the groups arbitrarily
https://docs.google.com/spreadsheets/d/1vySXTTOP--QQlJTkpoMy7DvgAi1Kvp-d7pnzvG7xRrw/edit?usp=sharing
mphone*g - 0.2*g = (mphone + 0.2) a where
mphone to be determine
g  = 9.81 m/s^2
a is found from the phyphox data as about 1.1 m/s^2
I assume the data is for 200 gram as a counterweight for the pulley system
therefore mphone =(0.2*a+0.2*g)/(g-a) =0.250 kg
that can be verified from a weighing machine on the bench

handwritten newton's second law applied to the pulley system

data from one fo the groups
https://docs.google.com/spreadsheets/d/1vySXTTOP--QQlJTkpoMy7DvgAi1Kvp-d7pnzvG7xRrw/edit?usp=sharing
using excel and applying $ v = \int a dt $ and
 $ s = \int v dt $

only for Android users, enroll for the beta users program
https://play.google.com/store/apps/details?id=de.rwth_aachen.phyphox&hl=en_SG
and the update should be available after a few minutes

benefits in the beta version can pick data and read off, no need to hotspot your phone and remote data into the laptops

example of little zero error

example of a large zero error can be overcome by rotating the phone from side to side to allow the phone to re-zero

collision handphone for acceleration data
