A pair of these trolleys are used for investigation on momentum velocity, acceleration etc. Both the trolleys are identical and each consists of a two rectangular wooden blocks 300 mm long moving on three low friction wheels. The trolley is fitted with spring loaded impulse rod. Rod has three positions to provide different impulses which is triggered by a release pin, In the front of each trolley two holes are drilled and fitted with corks. With removable metal pins at each end to enable trolleys to be stacked or to provide anchoring points for accelerating cords.

Description
A
Trolleys with rubber wheels fitted with ball bearing
For the measurement of velocity and acceleration, using timing marks made on a moving paper tape by a vibrating striker. Designed to operate on a 12V A.C. supply and uses the mains frequency as its timing standard. The unit is housed in a moulded case including mounting flanges. The top of the case caries a tape guide which incorporates a carbon paper disc support and an adjustable anvil for the striker point. All moving parts are fully enclosed and a pair of 4mm sockets are provided on the side of the case for connection of the electrical supply. Supplied complete with a roll of self marking 9.5 mm paper tape of lt. 100 metre. And Carbon Paper Discs of 40mm diameter, with 3mm hole, cut from long life plastic film type carbon paper.
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 levelling 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 millimetres 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 215mm)
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
