quick symbol notation: physics

<p>I saw this on a sparknotes SAT II physics test, </p>

<p>for some reason those “E” (euro symbol) showed up in there, just ignore those.</p>

<p>This symbol means “Pi”, or 3,14, because are dealing with a centripetal force.</p>

<p>*you are dealing</p>

<p>ah, gotcha. thanks</p>
