Explain. 2 ) How does the coefficient of kinetic friction compare with the coefficient of static friction determined in all parts of the experiment? 3) What are the sources of error in each part of this experiment? What is your estimate of the error in each part of this lab? 4 ) For Parts CI and C2, does your data indicate a dependence of the angle of the incline on the block mass? (Within your estimate of experimental error) 5 ) Can you conclude that your data supports the theory for part CI and C2? 6) Look up the coefficient of friction for wood on wood. Which method do you think gives the most accurate measure of the coefficient of friction
