Kinetic Friction Experiment
... Kinetic friction forces are the forces that sliding surfaces exert on each other parallel to their surfaces. Kinetic friction forces are cumulative effects of the forces between all the microscopic contact points of the sliding surfaces. As a result, friction forces vary with the types of surfaces i ...
