<p>Does anyone know any tricks to converting between vt/dt graphs?</p>
<p>what exactly are you asking?</p>
<p>ACtually looking at a vt graph and drawing the corresponding dt graph.</p>
<p>I don’t take AP Physics, and I’m probably misinterpreting your question, but are you talking about velocity and distance graphs? Isn’t Velocity the derivative of a motion graph?</p>
<p>if you have a VT graph you must remember that distance is the area under the curve.</p>
<p>ohh velocity-time. not all of us are cool and use abbreviations you know.</p>
<p>the distance to time is just the integral of the velocity to time</p>
<p>all right thanks…unleashed fury…and sorry for assuming that everyone was cool</p>
<p>Just find the integral…because all the V(t) graphs are usually linear (if they weren’t then we’d have a variable acceleration…and CB doesn’t like that. </p>
<p>So just integrate it and graph the curve.</p>
<p>Ap. Physics. Is ez as heck</p>
<p>does anyone know what percentage of the pts u need for a 5, 4, and 3?</p>
<p>^ (10 chars)</p>
<p>^ does anyone have info on this?</p>
<p>According to my Princeton Review Physics AP guidebook, you need approximately 75% or higher for a 5, 60-74% for a 4, 45-59%, for a 3, and 35% or higher for a 2. The exact percentages will vary year to year, though, as the test is graded on a curve. Good luck! :)</p>
<p>thanks cheddar</p>
<p>Think Calculus, that’s the best way (integral and derivative)</p>
<p>Using the 1998 and 2004 Physics B exams:</p>
<p>1998</p>
<p>5 106-180 (59%-100%)
4 83-105 (46%-58%)
3 54-82 (30%-45%)
2 40-53 (22%-29%)
1 0-39 (0%-21%)</p>
<p>2004</p>
<p>5 115-180 (64%-100%)
4 91-114 (51%-63%)
3 63-90 (35%-50%)
2 49-62 (27%-34%)
1 0-48 (0%-26%)</p>
<p>So a safe 5 would be about 125 - 130 points?</p>
<p>all right so tge slope of the xt graph is the y-int of the vt graph and the slope of the vt graph is the y-int of the at graph.</p>
<p>got it!</p>
