The fan has three speeds for studying the effect of variable thrust. Two mass bars let you change the total mass of the cart to observe how mass affects acceleration. The fan turns on a protractor base, allowing the thrust to be directed at a known angle from the direction of travel. In this way students can understand vector component applications.
A sail is included to perform the fan-on-a-sailboat experiment. The sail can be mounted in two positions to study the subtle effects of diverted airflow.
Although the cart can be used for qualitative experiments alone, most often it is used with a Motion Detector on a Dynamics Track.
