Hall's Friction Car

Hall's Car is a one-piece molded plastic car designed for dynamics experiments. It features plastic molded wheels with sleeve bearings that absorb friction and reduce vibration, a central well (2.3 x 2.2 x 0.9 inches) for placing additional masses, and a removable metal thumbscrew for attaching cords. Overall dimensions are 5.5 x 2.3 x 1.4 inches, weighing 2.2oz. The car can be used with an inclined plane, weights, and pulleys (not included) to study the relationship between energy and work. Suitable for classroom physics experiments.
