The lab was set up so that a glider was set on an air track, and a constant force would push the glider along the track. The first experiment involved an air track raised at different heights only on one side. The higher the track was raised, the greater the acceleration of the glider. The other experiments, differentiated only by differing glider masses, both used the air track at a level position, and used a hanging mass to pull the glider along the track. The acceleration was found experimentally. For the first experiment, the obtained data was used to find an experimental value for g, and then the % error was found for the difference between the experimental and actual values of g. The same was done for the other experiments except with respect to m1 instead of g. Experiment Table 1 Data Table Exercise 1 D (cm) =100 H (cm) sin(theta ) a (m/s^2) 1.29 0.0129 0.132 2.59 0.0259 0.263 3.89 0.0389 0.384 5.18 0.0518 0.516 Calculated G 9.8148 Percent Error 0.05% Table 1 deals with the data used to find the experimental value for gravity, or g. In this exercise, the air track was raised up a certain height, and then the acceleration was recorded at each height. Also, the angle of the incline was found by take arcsin of the Height (H) divided by the Distance (D). The g value was found by making a graph and making a line whos slope is: a/sin(theta). The experimental g value was found to be 9.8148m/s^2, while the actual value is 9.81m/s^2. The percent error between the two values is a negligible .05%.
