Our uncertainty on the measurement of theta is derived by summing the percentage errors in our length measurements. We next added mass to the glider in increments of 100 grams and again made several measurements of acceleration for each of our two heights. The analysis of these trials follows exactly as described above for the unweighted glider. We discuss the significance of these results in the next section. This section discusses the significance of your results.
Styles can differ here.
Others would, with the same experiment, trumpet the magnificence with which the conventional theory predicted the experimental results. The style you choose depends on what you expected to see and your own personal taste. Your analysis should also describe difficulties and shortcomings that you encountered during your experiment. You must suggest experimental redesigns to eliminate and overcome these troubles. Now note that there is a subtle point here.
