how to calculate coefficient of static friction on an incline
1. understand that a coefficient of friction could be determined via an inclined plane; 2. collect experimental data and calculate the corresponding results of coefficient; 3. compare the values of coefficient generated from different pairs of surfaces.. Gradually increase the slope of the plane until the penny first begins to slide down, and record the angle of the inclined plane on the data table below. 3. Repeat Step 1 and Step 2 twice, and apply a formula ms = tanq to calculate the coefficient of friction for those three trials.
