Measurements were taken as a ball falls a distance D in a time T are: D = 1.215+ 0.004 m T = 0.495, 0.498, 0.530, 0.496, 0.501 s ) The mean value of T. The acceleration due to gravity g, using the formula: g=\frac{2 D}{T^{2}} Percentage uncertainty in D. Range in measurements of T ) The absolute uncertainty in the average value of T. The percentage uncertainty in the average value of T. The percentage uncertainty in g. ) The absolute uncertainty in g.
