Links & Practice sets for March 14-19

Periods 3-4, 8-9
Wednesday, March 14:
First, reach consensus on the homework from Tuesday night, using energy.

Here's the initial video for rolling without slipping.  There is a second one with an example of a frictionless hill, so check them out and take notes on each before trying the practice problems.

Try the AP Probs for 1994, 1997; pages 18-19 in pack.

Thursday, March 15:
Reach consensus on the homework set, any volunteers to work parts in question on the board. 
Work on the lab with the rotations contraption.

Overnight, try 'the cat problem' on page 17 (AP from 1996).


Friday, March 16:
Complete the lab and report, share with vondracekm@eths202.org.

Check out a video on non-constant torque and non-constant angular acceleration. Try the AP Problem from 1999 on page 15 for Monday. Note that at the bottom of the page, add in to also find the angular velocity of the contraption when it goes from its starting position to the horizontal position shown in the diagram. Use energy conservation to find speeds.


Monday, March 19:
As a group, go over the 1999 problem from the weekend.

As a collaborative in class, try the 2002 AP Problem on page 14. Turn in a group solution before you leave.
Tonight, try the torque brain teasers on page 9.

Before leaving, check out a video on rolling AND slipping, take notes. We will see where all this stands tomorrow!! Thank you for your hard work while I am gone!!  :-)
