In this practical you will determine the static and kinetic friction coefficients of different materials on wood. To do this, you place objects on an inclined plane and take measurements. You then use formulas you learned in class to determine the friction coefficients from the measurements. This practical consists of two parts. Supplies Wooden plank Tape measure or ruler 3 objects Stopwatch Part 1: Static Friction Coefficient In the first experiment you will determine the static coefficient of friction of different objects on a wooden plank.s 1. Draw the free-body diagram of an object (block) on an inclined plane at an angle. Place your VLS in this box. 2. Show that for the largest slope at which the object does not slide down s = tan (6) Place your distraction in this box.
