Encoder Fan Cart
The Encoder Fan Cart is a large fan on a light-weight cart. It offers students the ability to perform kinematics and dynamics experiments with constant acceleration, variable mass, variable thrust, and variable thrust angle. The cart includes a Motion Encoder Transmitter for use with the Motion Encoder System.
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 investigate 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 Encoder on a Dynamics Track.
A Fan Cart without the transmitter is available at a lower cost.
Effect of thrust angle on acceleration. We expect that the component of the force parallel to motion will be proportional to acceleration.
