Conclusion: In this lab, we determined the speed of a glider as it slid down a frictionless incline. By observing the initial speed, the final speed, and the time taken to complete this path we can determine the acceleration of the cart, which should be the force of gravity. In our calculations, we used two methods to calculate the average acceleration of the cart. First, we graphed our v2 values versus T values including error bars and took the slope of the line. The slope of the best fit line gave us the average acceleration. Then, we graphed the same graph without the best fit line. On this graph, we drew two lines, one with the maximum possible slope and minimum possible slope. Then, we took the slopes of these two lines and averaged them together to get an average slope of the two lines. This gave us an average acceleration of the glider. The first graph was a lot more precise because you are taking the best fit line through all the points. The second graph lacks precision because the data points used to take the slope are just average points and you could make
