Motion in Cylindrical Coordinates

AI Thread Summary
The discussion focuses on clarifying the second component of acceleration in cylindrical coordinates, specifically the expression for a(theta) at a referenced time in a video. Participants identify a mistake in calculations due to using degree mode instead of radians, which led to an incorrect answer. There is an emphasis on the importance of posting new problems in separate threads for clarity. LaTeX is appreciated for enhancing readability in mathematical discussions. The conversation concludes with acknowledgments for assistance and a commitment to improve future problem postings.

7:03 what is second component of a(theta)? this -> 2 * r' * (theta)'
I understand everything except that.
 
Physics news on Phys.org
See expression for ##a_{\theta}## at time 1:27 in the video.

See equation (4) here.

There is no explanation at 1:27, but link is good.
Thanks !

Can someone find mistake?
Correct answer is 12,66N.I am learning LaTeX !

In the future, a new problem should be posted in a new thread.

I believe the only mistake you made in your solution for the new problem is that your calculator was in degree mode while your angles are expressed in radians.

I posted it on new thread. Someone merged it.

I will try that.

I get correct answer now.
Thanks !

That would be my fault. I didn't click into the link for his 2nd thread start, thinking it was the same as the original one (which I had locked in a different forum).

Thank you for doing that. It makes it so much easier to read and reply to your calculations when they are in LaTeX. Looking forward to seeing your next thread! :wink:
