Pair of Dynamics Trolley Centrifuge Tube hole for screwing the compassIncludes a pair of Dynamics Trolley (2 pieces). Made from rigid ABS plastic, these trolleys have accurately aligned, very low friction wheels. Coupled with their low profile and accurate mass of 600g, this allows a range of kinematic experiments to yield high quality data. The two position firing pins have a locking catch for safety and the trolleys have Velcro pads for inelastic collision experiments. The trolleys are stackable and can withstand
