Thus if you are calculating a number y = g t2, where t = 2.36 .04 sec, then the uncertainty in t2 is 3.39%. It only takes a minute to sign up. (largest - smallest value) We have been using the Monte Carlo method to propagate errors thus far, which is one of the most powerful and versatile methods out there. For example, if we limit ourselves to 0.1 percent accuracy we know the length of a meter stick to 1 mm, of a bridge 1000 meters long to 1 meter, and the distance to the sun (93 million miles) to no better than 93,000 miles. ). 1) An electron in a molecule travels at a speed of 40m/s.
