A set of dynamic cart trolleys are used for investigation on momentum, velocity and acceleration. Each trolley consists of two rectangular wooden blocks, 300 mm long, moving on three low friction wheels (ball bearings in wheels). The trolley is fitted with spring loaded impulse rod. It has a provision for stacking the trolleys on top of each other with removable pins. It is supplied with two rubber corks and 2 needles, so trolleys may be stuck together for inelastic collisions. A striking pin for releasing the striker and 3 pins or dowels for stacking are provided. One trolley weight approximately 1 kg.
