I am developing an iPhone application that is supposed to calculate acceleration in m/s. To be honest, I know I can calculate the values using the distance coordinates from the GPS, but I’m not sure if they will update as frequently as I’d like them to. With that in mind, I wanted to use the accelerometer.
The values I want to put out are going to be in m/s, i.e. 0.72m/s, etc.
What is the best way to go about this and get started?
Read about Core Motion.
Core Motion reports acceleration in units of Earth gravity, so multiply by 9.81 to get m/s.
