# accelerometers vs gyroscopes

In terms of semiconductor integrated circuits, is there any difference between an accelerometer or a gyroscope? are they the same part?

Can I get a IC recommendation for something with 3 axis?

They're not the same part.

Accelerometers measures linear forces. That is, forces acting in a straight line:

                ^

<--------------->

v


Gyroscopes measures rotational forces. That is, forces acting spinward:

                 -----.
\
^            |
|            v

Both are available as 3-axis devices.
