How can I find the velocity using accelerometers only?

Question

Using only the phone\'s (Android) built in accelerometer, how would I go about finding its velocity?

I have been tinkering with the maths of this but whatever funct

Answer 1

If the phone is at standstil, you have ZERO acceleration, so your speed is 0. Probably you should find location data from GPS and get the associated time samples and compute velocity distance over time.
