Theoretically, a perfect accelerometer would give you your relative velocity change, and if you knew the initial velocity, you could get your relative position change.
In practice, you don't have a perfect accelerometer-- they have sample rate limits that are pretty coarse for kinetic analysis, and it's easy to exceed the force limits giving you garbage data samples. MEMS are amazing things, and oh so inexpensive, but they're not magic. On Apr 27, 7:20 am, lbendlin <[email protected]> wrote: > TreKing, this just gave me an idea.
