3A20.35 - Air Cart Masses and Springs - Air Track & 2 Springs

Code Number:
3A20.35
Demo Title:
Air Cart Masses and Springs - Air Track & 2 Springs
Condition:
Good
Principle:
Velocity in an Oscillating System
Area of Study:
Acoustics
Equipment:
Air track, Spark car for air track, Matched springs (2) (for air track), , Single pulley for air track, Plexiglas Spring Attachment, Masking tape, Masses (3) (50 g, 100 g, 150 g), Timing gates and counters, Large Hoop Springs, Spark generator, Spark tape.
Procedure:

Attach the Plexiglas bar across the air track at the midpoint. When using the spark generator be sure that there is nothing to cause a short circuit.  Attach the sparking pins to the desired car.  Set the car into the track, position a length of tape under the sparking pin and tape to the railing with masking tape.  Practice will be necessary.  Timing gates and counters may be used if desired.
