AP Physics acceleration from gravity - 10 or 9.8

<p>I'm still unclear about which constant we're supposed to use on the Physics B test.</p>

<p>Do we use 9.8 m/s^2 for the acceleration from gravity, or do we use 10 m/s^2?</p>

<p>Also, do we use the same constant for both MC and free response? (I know we're not allowed to use calculators on the MC).</p>

<p>10</p>

<p>Use 10 for MC and 9.81 for FRQ (you might be able to use 10 for frq but why not be more accurate).</p>
