Using the Smart Fan Accessory with a Dynamics Cart

Assembly

As with the Smart Cart, snap the sides of the Smart Fan 

Accessory over the rails of the Accessory Cart of the 

PASCO Dynamics Cart.

Operation

1. Press the ON/OFF Speed Control Button to start 

the fan. 

The fan starts at low speed. 

2. After starting the Smart Fan Accessory, change 

the fan speed by pressing the ON/OFF Speed 

Control Button as follows: 

One press changes the fan speed from low to 

medium, a second press changes it from medium 

to high, and a third press returns it to low.

3. Press and temporarily HOLD the ON/OFF button 

to stop the fan.

Suggested Experiments

Experiment #1: Measure the acceleration of the cart with the Smart Fan Accessory using the a Motion 

Sensor (or equivalent). Vary the mass of the cart or the fan speed of the propeller and repeat.

Note: To prevent the Smart Fan Accessory from coming off the cart during a collision with a wall or an 

End Stop, secure it to the cart with a rubber band as shown. 

Experiment #2:  Determine the force of the Smart Fan Accessory by connecting the cart to a mass that 

hangs over a pulley. Adjust the hanging mass until the cart doesn’t move. Vary the fan speed and repeat.
