<p>FUN FACT!</p>
<p>angular momentum can also be measured in Joules/Second</p>
<p>modern physics, quatam theory</p>
<p>btw how many do I actually have to get right to get a 5?</p>
<p>$\bump$ Q.E.D.</p>
<p>btw how many do I actually have to get right to get a 5?</p>
<p><em>wonders the same</em></p>
<p>hmm i heard somewhere its around 75%.. thats really high!</p>
<p>omg!!!!! That's HIGH!</p>
<p>i know... =(
it's in the introduction section of the PR book.. in case you want to verify</p>
<p>oh and does anyone know what labs we need to know for physics B?</p>
<p>*** labs? NOOO EROIEHR#%<em>U$#(%</em>$(%<em>$U%(</em>$%435555</p>
<p>i know... we barely did any lab at all.. i was practicing with old AP's today, and i have to resort to my chem background for a calorimetry lab</p>
<p>I've been noticing that on the old AP MCs there are couple of questions regarding famous experiments. Let's try to compile a list of experiments that we should know about. </p>
<ol>
<li>Compton experiment </li>
</ol>
<p>(edit names of experiments as needed)</p>
<p>Also "analyze the motion of a particle of specified charge and mass under the influence of an electrostatic force." </p>
<p>What is that supposed to mean?</p>
<p>"Students should understand the concept of electric field, so they can: Define it in terms of the force on a test charge."</p>
<p>Is that supposed to be E=F/q</p>
<p>But then if I assume that it conflicts with this:
"Caculate the magnitude and direction of the force on a positive or negative charge placed in a specified field."</p>
<p>I think you have it...</p>
<p>I guess that's the subtle differences between...</p>
<p>F = E * q</p>
<p>and</p>
<p>E = F / q</p>
<p>So the force on the charges would always be tangent to the electric field lines?</p>
<p>Shouldn't the force be parallel to the field lines? I'm not really sure..</p>
<p>I'm not sure if it's talking about "force charge placed in electric field," but it's on pg. 197, the diagram.</p>
<p>Ooo so it's kinda like the charge moves in a parabolic motion, lining up with the field line?</p>
<p>Something like that according to the book. BTW, anybody know what the raw score ranges are for the test?</p>
<p>For example
5= 150-115
4= 90-115
3= 75-90
2= 45-75
1= 0-45</p>
<p>Also, 75% is insane for a test that covers so many difficult topics...</p>
<p>these are raw scores, right?</p>
<p>so it's 1/4 for wrong + 1 </p>
<p>-5/4</p>
<p>oops, I meant final score ranges that can be compared to 5,4,3,2,1.</p>
