Description:
Place masses on a wooden block and pull the block with a spring scale (or Force Probe connected to computer to plot Force vs Time). A larger force is needed to get the block moving (static vs. kinetic friction). Add mass to show friction is dependent on the normal force. One block the center is hollowed out to show that friction is independent of contact surface area. Blocks with foam rubber and a rubber sheet are available to vary the coefficient of static friction. Using the computer and Force Probe dramatically shows the difference between Static and Kinetic friction.
