Triangular section track made of aluminum with perforations. An inlet cover is given at one of the ends, which is connected to hose of an air blower. The gliders move on an air cushion thus minimizing friction. Used for performing experiments to investigate law of motion, speed, acceleration, and momentum. All the experiments can be conducted in an inclined or horizontal position. It can also be used to determine ‘g’ by free fall when made to stand on ‘A’ shaped base. Adjustable solenoid may be clamped on a holder.
