<p>How do you find the displacement in a velocity/time graph?</p>
<p>Is it the area under the curve or do I use the following formula:</p>
<p>X= Xo+ Vot + 1/2 at^2</p>
<p>In general, the displacement is equal to the integral of v dt (“area under the curve”), written as ∫v dt. Usually it is a definite integral, so you will have to evaluate at some t = t<em>f and subtract the value at t = t</em>0.</p>
<p>For projectile motion, ∫(v0 + at)dt = (1/2)(at^2) + (v0)t + x0 (this is where the formula comes from). The displacement is just X(t<em>f) - X(t</em>0).</p>
<p>Thank You (: I learned new things today :D</p>
