Horizontal Surface Method 1- Set up your experiment as in the following figure 250 y= 0.675x + 142.5 200 150 Hanged Mass MA (8) 100 50 Figure 4: Horizontal Surface Method 20 40 60 80 100 120 Added Load 2- Measure the mass of the glider Mc = 213 g M. (g) 3- Add extra loads M. to the glider based on the table below. Make sure to divide each mass on both sides of the glider for balancing. 4- Gradually, increase the hanging mass until the glider just starts moving. 5- Plot the hanged mass Me (y- axis) vs. the added masses to glider Ma (x-axis). 6- The slope of the fitting line equals the coefficient of static friction. What is the ratio between the graphically determined value of us and the average value?
