    I'm trying to calculate the percentage uncertainty for terminal velocity in my experiment, (core practical 4- falling ball practical to determine the viscosity of the fluid) I'm starting with working out the percentage uncertainty of time. However ive taken two different readings - one for how long it took the ball to fall through the first half of the length of glass and the second reading for the second half. If I was to calculate the percentage uncertainty for this, would I take the mean average of the two time results? Or do them both separately and add them?

    You need to combine the uncertainties. How to do that is explained in the thread below:
