3. Should the results of your experimental Coefficient of Static Friction for the Wooden Block with sandpaper (Data Table 3) and the wooden block with sandpaper and added mass (Data Table 4) be similar? Explain why or why not. Determine whether the results of the experiment are within a reasonable experimental error (<10%) by calculating the % difference. The results are within reasonable experimental error at 9.4% and are consistent even though it is close to 10. |0.851 – 0.935| % Difference = x 100 = 9.4% 0.851 0.935 2
