Additionally, it tells the Δx, or the distance the ball traveled horizontally. The uncertainty in height and angles is also given. The uncertainty in angle is simply 1 degree, determined from the scale. Additionally, part 1 of the report shows all of the collected times and ranges for both a short range launch and a long range launches. Short Range: Average time of flight Standard deviation = Uncertainty time = Standard error = Average Range =
Uncertainty of Range = Average Initial velocity = Uncertainty of initial velocity = m/s Initial velocity = 3.192m/s ± .28 m/s
