This The Mu of the Shoe activity also includes:
What is mu? Emerging scientists explore the coefficient of sliding friction, or mu, and apply its concepts as they complete activities in the interesting lesson. They measure the sliding friction between soles of their own athletic shoes and different materials on floor surfaces. They conclude by calculating the effects of frictional forces on multiple objects that you determine before the activity begins.
