<DIV><FONT face=Arial size=2>Hi All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have been doing some US this year and have used
some US tests from various places and tried writing some based on the US
performance criteria.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Looking at US6397 for level 3 mechanics I have
element 1 asking for <STRONG>three of</STRONG> : angular displacement, initial
angular velocity, final angular velocity, angular acceleration, time.
Calculations and units.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Element 2 asks for rotatioal kinetic energy,
gravitational potential energy, torque, rotational inertia and angular momentum.
Calculations and units.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My question is: For element 2 do I need the
students to satisfy <STRONG>all</STRONG> the conditions or just
<STRONG>one</STRONG> of them?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>By the way, does anyone have loads of US tests that
they are willing to share with me? I am writing things myself but feel that I
must be reinventing the wheel. I'll show you mine if you'll show me
yours.</FONT></DIV>

The kids love it.</FONT></DIV></BODY></HTML>
