LINEAR AIR TRACK APPARATUS

For exploring the concepts of mechanics involving linear motion on a near frictionless surface, such as acceleration, collisions (elastic / inelastic), explosions, conservation of momentum and simple harmonic motion etc. Air track, the principal component of the apparatus, comprises of specially designed, rugged, anodized, aluminium alloy extrusion providing a straight working length of 2m, is mounted on four cast metal feet with leveling screws, two on each side positioned along the length. Two rows of fine holes provided on each side all along the length of the track through which jets of the air emanate to form air cushion on which the vehicles float under virtually frictionless conditions. One end of the track has an air inlet tube connection for compressed air supply. The track also has a 0-200cm scale graduated in millimeters for measuring distances and recording positions. The kit includes various gliders, which float to and fro on the air cushion, together with a large number of attachments to permit a comprehensive range of experiments. The complete apparatus including Air Track and attachments/accessories are packed in kit form. Linear Air Track is supplied complete’with following accessories. 2 large vehicles (mass 400g, length 215mml, 1 small vehicle (mass 200g, length 100mm), 2 magnetic buffers (25mm diameter), 2 Plasticine holders (20mm diameter) with central hole 4 catapults (45mm wide) with slot for elastic band, 3 steel buffers with central hole, 4 elastic cords (220mm long) with plastic rings 1 reel of nylon thread, 2 white plastic rods (4mm diameter 150mm long) for stroboscope photography, 24 needles for use with steel buffer, 20 white plain cards for interrupting light beams 1 reel rubber stand, 1 pack of Plasticine, 20 elastic bands.
