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.
