<p>Which constants or other numbers (if any) do we need to know for SAT II Physics? Do we also need to know things like 1 cal = 4.19J ?(Conversion factors)</p>
<p>Thanks !</p>
<p>the only constant you should know is the speed of light and sound, 3x10^8 m/s and 343 m/s respectively, the other hard constants they will give it to you if needed. You do need to know simple conversion though, like going from centi to milli and so on.</p>
<p>Thank you so much for the response :)</p>
<p>As far as conversion goes, I meant do I need to know conversion factors such as the one I mentioned?</p>
<p>nop, they’re too specific,remember the test is without a calculator so all the math is simple and the majority of the questions are conceptual.</p>
