3/30/2013 5:47:27 AM Take the difference between your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to be 8m/s2, and you know that the true/known value is 9.8 m/s2, the percent error would be l 8 - 9.8 l / 9.8= 0.1836 or 18.36%
