Purpose: To demonstrate how to find the coefficient of static friction of different materials.

Pasco track with incline accessory, string, weights, and friction boxs with different surfaces.

Set up apparatus as shown in photo, and then place weights on pulley system until the block begins to slide. Measure the components of the gravitational force with the help of the protractor. Then, calculate the coefficient of friction. Repeat procedure with another friction box with different surface materials.
