Which way does the acceleration point?

Desmos FTW!!!

Desmos can do what I hoped it could do.  Here’s a screen cap of the command(?) that I had to throw into it. My data table has the period in the X1 column, and the Fuc in the Y1 column, but I want to plot Fuc v. angular velocity.   

I had to tell Desmos to plot (2*pi/X1,Y1)

So now on my graph I have this….

 

…pretty sick, I know.

Drake Physics Prize Exam Sign Up

Registration for the Drake Physics Prize is open.  Enter Nathan Frese as the name of your proctor, (his email address follows the standard lastname.firstname@iowacityschools.org format) and enter Iowa City West as your school.  

Drake Physics Prize Exam Student Registration Link

The exam at West will take place on Wednesday, February 1st in the West Wing Conference Room (9th grade center office), from 2:00-4:00.  You'll be excused from 6th and 7th period that day.  Please let me know when you have registered, as I have no other way of knowing in advance of the exam, and I need to arrange for sufficient laptops and calculators, etc.

CVPM and CAPM (with a new spin?)

Rotational CVPM
The wheel in this video becomes interesting once the hand loses contact with it.
Create quantitative graphs of Angular position v. time, angular velocity v. time, and angular acceleration v. time.
(if that link doesn't work, try this)


Rotational CAPM
Download this video and create quantitative angular velocity v. time, and angular acceleration v. time
graphs.

(If that link doesn't work, then I just give up)

Mod sum

FG success!
