In theory, you can calculate velocity by integrating the accelerometer values. So for example, along the X axis, the output is dv/dt. Thus new v = old v + current dv/dt * time since last dv/dt. However, the accuracy of the accelerometer is questionable. With some more math you could get rotations, at least.
I suggest you write a little test app and get to know how the accelerometer really works.
