HFC33 Conservation of Linear Momentum
The HFC33 apparatus consists of a long precision air track manufactured from sturdy lightweight extrusion. A blower forces air through the extrusion and miniature holes running along its length. This creates a near frictionless ‘cushion’ of air onto which two trolleys can me moved which is crucial in preserving momentum in the Conservation of Momentum theory.
The trolleys can be set onto each other in different modes. The trolleys can accept additional masses onto them to vary the experimental parameters. The trolleys are projected along the air track by means of a catapult device with buffers installed to stop the trolleys if necessary. Light gates on the track monitor the timing of each trolley and a linear scale allows the distance to be recorded and the timing gate positions to be accurately set. The apparatus can also teach kinetic and potential energy, velocity, acceleration and force.
