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.
