Students conducted an experiment to investigate the relationship between friction force and different variables like mass of an object, type of surface, and motion. They set up a pulley system with a reel and timber to allow objects of varying mass to be pulled across different surfaces. The students observed that increasing the mass led to an increase in friction force, and changing the surface also impacted the measured friction. The experiment helped demonstrate Newton's second law.
