Document Summary
Lab report for m5 experiment: newton"s second law of. Vi(1) in this experiment we verified newton"s second law of motion by studying the one-dimensional motion of a glider on an air track. We calculated the acceleration in cm/s2 five times per mass. I then calculated the average of these accelerations as shown below. I graphed m2 in excel and then using linest i found the slope, s, intercept, b, and the uncertainty in each of these values. M2 (g) a a a a a (cm/s2) (cm/s2) (cm/s2) (cm/s2) (cm/s2) Vs. m2 f(x) = 2. 97x + 1. 55. 0 s = 0. 336402 s = 0. 000762 b = -0. 52219 b = 0. 045188. Using newton"s second law of motion, i was able to calculate the acceleration due to gravity, g. M 1+ m 2 g = s(m1 + m2) g = 0. 336402(294. 8 + 20. 0) = 105. 8993496 cm/s2. Least decimal of answer is same power of 10 as uncertainty.
