Static v. Kinetic Friction

PIRA: 1K20.30

Materials: A brick, A brick with sandpaper, A brick with wood pieces duct taped to it, A long piece of wood to slide the bricks on, Pasco 850 Universal Interface, laptop, Capstone, Force Sensor with hook

This demo is to show that static friction coefficient is much larger than kinetic friction coefficient. This is done by pulling bricks with the force sensor hook slowly until the brick starts moving and keeps slowly pulling. This will show on capstone that the force of static friction is higher because of what the graph is showing. The wood that the brick is being pulled on can not be painted on as this will cause issues with the friction reading. Also be sure the wood is at least 4 feet long so there is space to pull.
