Abstract
If Galileo had had a smartphone... could he have proved that Earth rotates about its own axis? Perhaps! For that he could have used the accelerometers, which they all contain. Their reliability for carrying out scientific experiments has been tested numerous times [1-7]. Thanks to them we can measure the value of the acceleration due to gravity. It turns out that this value changes according to our latitude, mainly due to the centrifugal effect linked to this rotation. In this chapter we propose an easy method that can be used to detect this effect. It will suffice to measure the value of the acceleration due to gravity, which will be measured at different latitudes with a smartphone during a trip.
