1) there is force on the object (thus it can be sensed by an accelerometer);


If you're using an accelerometer to sense rotation, you're assuming:
1) The accelerometer is not at the center of axis of rotation.
2) The distance from the center of rotation to the accelerometer is known.
3) A second accelerometer is being used so tilt can be differentiated from spin.
4) All of the above.

But to answer your question, if an object is rotating at a constant angular velocity then there is no force being applied to it. Acceleration is a change in velocity.

You would be correct.



Ummm....Newtons first law disagrees with you.

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Thanks folks for the clarification.


You're going to be be disappointed.

Don't blame me though, I only own one of the things and have seen it with my own eyes.

Then what's keeping the earth from falling into the sun?

Q1: You are going east at 1km/h, and then  you go west at 1km/h. Is there a change in velocity?

Q2: what does that mean in the context of the boat?

Millions of people have seen a flat earth.

If we all believed in our own eyes, we would still be in the dark age.
