Accelerometer record g-force?

I am wondering if anyone who has experience with accelerometers can tell me in their opinion if an accelerometer could detect the twists and turns associates with sitting on a small rollercoaster? I would like to record those parameters.

If so which would be the best accelerometer to purchase for this?

Cheers.

Yes that is the sort of thing it would do very well. However, as you are likely to be pulling several G look for a sensor that will handle it. Have you seen the seismometer application on the iPhone / iPod touch?
